  • Recent review up at The Register

    A thorough six-page review, with interspersed interview-bits, is here:
    theregister.co.uk/2008/06/20/mackay_on_carbon_free_uk

    A topflight science brainbox at Cambridge University has weighed into the ever-louder and more unruly climate/energy debate with several things that so far have been mostly lacking: hard numbers, willingness to upset all sides, and an attempt to see whether the various agendas put forward would actually stack up.

    Professor David J C MacKay of the Cambridge University Department of Physics holds a PhD in computation from Cal Tech and a starred first in Physics, so we can take it that he knows his numbers. And, as he points out, numbers are typically lacking in current discussion around carbon emissions and energy use.

    MacKay tells The Reg that he was first drawn into this field by the constant suggestion -- from the Beeb, parts of the government etc -- that we can seriously impact our personal energy consumption by doing such things as turning our TVs off standby or unplugging our mobile-phone chargers.

    Anyone with even a slight grasp of energy units should know that this is madness.

  • Diffuse fuels never scale

    If Nevada Solar One is averaging ~10 MW/sqm, it would need to be scaled up to ~50,000 square-miles to cover the present average electrical market of the United States. As the United States electricity market expanded to 10 times its present size, the solar power plant would need to scale up to ~500,000 square-miles (but that little, only if all of those square-miles were as optimal as the first square-mile), exceeding all of the "Warm Desert" land area in North America.On Solar thermal can save us, but it needs public clamor posted 1 year, 5 months ago 35 Responses

  • Do people believe that solar has to do with oil?

    The Tom Friedman article says that all oil use in the United States can be economically replaced "tommorrow" with "wind and solar power [...] on your roof."

    Now we have the new Bush energy plan: "Get more addicted to oil."

    People forget, wind and solar power are here, they work, they can go on your roof tomorrow. What they need now is a big U.S. market where lots of manufacturers have an incentive to install solar panels and wind turbines -- because the more they do, the more these technologies would move down the learning curve, become cheaper and be able to compete directly with coal, oil and nuclear, without subsidies.

  • Ultra supercritical means 50% efficiency

    Ted Nace wrote in the OP: World Bank policy is to invest in "abatement of climate change impacts" through "investment focus on ... supercritical coal technology, ultra supercritical [...]"

    Do not be deceived by fancy-sounding terms like "supercritical." We're still talking about burning coal, just at higher temperatures and pressures that notch the efficiency of the process upward from about 36 percent to maybe 43 percent.

    The potential efficiencies are higher than that:
    worldcoal.org/pages/content/index.asp?PageID=421

    Supercritical (SC) and ultra-supercritical (USC) power plants operate at temperatures and pressures above the critical point. This results in higher efficiencies - up to 46% for supercritical and 50% for ultra-supercritical

    CSP's on the other hand are more efficient, and therefore would only require 100 square miles to produce the same amount of energy.

    If we take that implied PV/CSP ratio to be at least 20 (2,000sqm/100sqm), and if we assume that PV has an efficiency of at least 10%, your statement seems to imply that CSP has an efficiency of at least 200%.

  • Industrial society and its reliance on creativity

    Wolverine wrote: solar power, by far the least environmentally destructive source of unnatural electricity

    Another observer wrote:

    When you attack these vital organs of the system, it is essential not to attack them in terms of the system's own values but in terms of values inconsistent with those of the system. For example, if you attack the electric-power industry on the basis that it pollutes the environment, the system can defuse protest by developing cleaner methods of generating electricity. If worse came to worse, the system could even switch entirely to wind and solar power. This might do a great deal to reduce environmental damage, but it would not put an end to the techno-industrial system. Nor would it represent a defeat for the system's fundamental values. To accomplish anything against the system you have to attack all electric-power generation as a matter of principle, on the ground that dependence on electricity makes people dependent on the system. This is a ground incompatible with the system's values.

    As Julian Simon pointed out, there is nothing that can be done to fundamentally block systematic expansion of human industry other than to fundamentally block human creativity. Demanding low-impact electricity is not fundamentally blocking industrial expansion. Demanding zero (unnatural) electricity is also not fundamentally blocking industrial expansion, since it could simply be interpreted as a differently-worded demand for low-impact electricity.

    Perhaps the optical-transistor, years from now, will, in fact, prove to have the potential to replace electricity. In that case, "the system" would have the additional option of simply obliging demands for zero-electricity by switching to optical powering of human-industry.

    Forcing industry to be low-impact does not block industrial expansion. Forcing human-population reduction (unless it is to zero, and in that case before a replacement can be created) does not block industrial expansion. Fundamentally blocking human-creativity (again, as long as a substitute has not been created) does block industrial expansion.

  • Stacked-streets vs. ignoring NYC gridlock

    Hapa wrote: street stacking is much more expensive to build

    Post-tensioned multi-story garages flowing nothing but PRT's would be expensive to build and maintain? Post-tensioned concrete construction is light, fast to build, and cheap. The 2009 NYC budget is NYC $59.1 Billion. Perhaps a billion every year could add substantial multi-level PRT capacity, without denting the budget too much. In the beginning, it might simply be restricted to the skyscraper districts, so that people could get from one skyscraper to another -- something that they cannot do now, because of NYC's permanent gridlock.


    Hapa wrote: street stacking is much more expensive to [...] maintain

    Why would garages flowing rubber-tire PRT's need maintenance? If titanium dioxide were added to the concrete mix, it would not even get dirty.


    Hapa wrote: NYC isn't starving to drive more.

    Are you kidding? "Gridlock has few defenders."

    Manhattan continuously improves density by adding building-levels. This is good, because it enables efficiency. The problem (bottleneck) is that the density improvement only takes place on the building-footprints. The street-footprint density never improves. This is because the streets always stay at a single level. The result is periodic elevator-gridlock and permanent street-gridlock. Street-stacking solves both.

    Imagine someone wanting to go from the 70th floor of one building, to the 80th floor of another building.

    By your subway system, he would:

    1. Descend 70+ floors to the subway level.
    2. Transit.
    3. Transfer.
    4. Transit again.
    5. Ascend 80+ floors.

    By your multi-level PRT-guideway system, he would:

    1. Transit.
    2. Transfer.
    3. Transit again.
    4. Ascend only 10 floors.

    By my multi-level PRT-flowing street system, he would:

    1. Transit.
    2. Ascend only 10 floors.

    The functional difference between my elevated PRT system, and yours, is that mine allows the PRT's to flexibly travel (randomly turn) just like taxi-cabs, whereas your system forces the PRT's to rigidly follow guideways. Perhaps a middle ground could be reached where your system would be enhanced to allow random-turns at intersections, or where my system would be paired-down to hug the buildings but still allow random-turns at intersections.


    Here is another enhancement idea: center-of-intersection elevators for the PRT's, which would then also use those center-of-intersection blockages as traffic-roundabouts.

  • PRT running on stacked-streets

    Gar Lipow wrote: automated ultra lights (PRT, JAD, and Cybertran).

    PRT and Cybertran are better than light-rail in that they are smaller/lighter (like cars), more flexible, less-capital-intensive and automated. PRT is more flexible than Cybertran, but even PRT is not as flexible as traditional automobile taxi service (nor "autotaxi", though it is similar in some ways to the latter). I think PRT would work well in Manhattan in combination with street-stacking. Street-stacking adds multiple street levels above a base level. Ordinary multi-level parking-garage construction-techniques (featuring efficient, garage-smooth "street" surfaces) can be used. At least some of the levels could be designated PRT-exclusive.

    With the street-stacks extending up into the sky, office-workers, hotel-guests, apartment dwellers, etc. could simply exit their building at their given floor-levels and catch a PRT, rather than take elevators (or, at least, elevators in their own buildings) to ground level. This way, there need not be a five-o'clock-rush to get to the ground lobby.

    What do you think?

    BTW, I could not find information on JAD. Could you please tell me what that is?

  • The Turks stopped walking when they hit turquois

    Wolverine wrote: I've always said "traditional" native people.

    Like the Turks that you reference? Turks (also known as Tibetans, Ainu, Chukchi, Eskimo, Navajo, and Dine) certainly have tradition, but they are not native to Southwest United States. (And "Not all Native Americans are Turkish.")

    One of their more-famous traditions was nomadicism. Another was worship of the copper-aluminium-phosphate mineral turquois (note the relationship: Turkish, turquois).

    In both Turkish and Navajo legends the first man is stated to have been made of turquoise.

    Turquois is an interesting mineral in that it is found in essentially only two places on Earth:

    1. Persia.
    2. Southwest United States/North Mexico.
    In most European languages the bright blue or blue-green stone is called "Turkish" because at the time of its introduction to Europe it appeared to have originated from the country of Turkey.



    Wolverine wrote: The traditional Dine have ALWAYS been opposed to ANY form of mining

    If that were accepted as true, it might be hard to explain this big pre-Spanish hole (from the above Persia-link):

    Turquoise [...] was called chalchihuitl or xiuitl ['xiu'=blue] [thus the word 'Mexican' might mean 'men of torquois' -NB], which are Nahua [as in Navajo? -NB] words. Nahuatl is the language of the Aztecs
    [...]
    The Nauhua colonial name for the Turquoise Hill on the north side of the Cerrillos was Cerro Chalchiquite. In the Argentine Andes the valley of turquoises is recorded as Valle de Chalchaquies.

    One of the smallest, but at the same time most important, of the Cerrillos Hills is Mount Chalchihuitl [...] the site of numerous prehistoric turquoise mines. The early Spanish visitors to New Mexico did not value the mineral -- there is no "Cerro Turquesa" -- but their central-Mexico allies and fellow-travelers, primarily Nahuatl-speaking Tlascalans, esteemed turquoise above all other stones. Hence, we have inherited through the Spanish records the Tlascalan name for this 'turquoise hill'.
    [...]
    Mount Chalchihuitl is the site of the most extensive prehistoric mining operations known on the American continent. The extent of the workings is "truly marvelous"; the whole north side of the hill has been quarried out, while less extensive excavations are found in other parts of the so-called mountain...

    William P. Blake, the first geologist to visit Mount Chalchihuitl, described it in Journal XII, the entry of August 29, 1857.
    [...]

    "A great chasm or excavation, basin shaped, with projecting crags and precipices. 200 feet deep - 300 wide - an enormous excavation into the solid rock and a pile of debris equally enormous. Trees growing in the bottom and at the sides, 20 feet high pines & very old. The rocks have caved in. A cave or shelter cut into the crags where Indians even now lodge.

    "Leaving the arroyo we ascended the slope of the hill following a foot trail among the cedars & gradually ascending until we reached the brink of a precipice which stopped our progress. Here we dismounted and clambering down among the crags looked off into an enormous basin shaped excavation below in the bottom and along the sides of which pine trees were growing. This excavation is nearly circular and is bounded on three sides by vertical precipices of rock, rugged and supporting trees here and there in the crevices.

    "I was so much struck with the extent of this singular excavation that it was some minutes before I could believe that it was the work of men alone and for an ornamental stone whatever it might prove to be. I looked in vain for traces of a mineral vein or bed of ore which might have attracted miners but there were none. In extent this opening is not not less than 300 feet in length and breadth and 200 feet deep and it must have been made the greater part of it centuries ago. The immense heaps or debris of the rock which has been removed is strewn out on one side and forms quite a hill which is over covered with pines - sufficient evidence of the antiquity of the opening. This is not the only pile of rocks which have been removed they are found on all sides and in most places are covered with lichens, gray with age. All the rock appears to have been broken up into fragments not larger than the fist or of eggs and then carried out and turned over the bank of refuses precisely as is done by the miners with their [] at the present day.


    In the words of Silliman,

    "The observer is deeply impressed with the enormous amount of labor which in ancient times has been expended here. The waste or debris excavated in the former workings covers an area which the local surveyor assured me extends by his measurement over at least 20 acres. On the slopes and sides of the great piles of rubbish are growing large cedars and pines, the age of which... must be reckoned by centuries." (Benjamin Silliman, Jr., 1881)

    According to measurements made by Sterrett in 1911, the main pit is about 130 feet deep on the high side, 35 feet deep on the low side, and 200 feet across, and the debris therefrom covers about 2½ acres. Many stone hammers and other primitive implements have been found in the debris of the ancient workings.

    Ancient excavations have also been found at the other points modernly worked and at several places in Turquoise Hill they exceed in extent the recent excavations.

    The immense excavations at Cerrillos are of great antiquity, and it seems beyond reasonable question that the greater portion was executed before the advent of the Spaniards. Indeed, this deposit must have supplied much of the turquois which was so widely used in pre-Spanish times

  • Cars more-efficient than trains - for people

    Hapa,

    Minivans hold people. Trains are only efficient when transporting dense cargo.

    A major reason why a railroad train is usually a lot more efficient for hauling freight than passengers is due to weight and space requirements. Hauling live people takes up a lot of interior space so that people can move about and have space to read, walk, etc. But freight just requires the space to store the freight. For bulk commodities like coal, there is little air space between the coal lumps.

    The weight of the passengers in a train is often only a few percent of the total weight of the train so the heavy rail cars and locomotives exact a high toll in energy consumption. In contrast to this, for high density freight, the weight of the freight may constitute roughly half the weight of the train. So the heavy rail cars don't accrue the high weight penalty that they do for passenger rail.

    • Passenger train cars have almost double the specific rolling resistance of freight cars due to the low weight of the "cargo" (passengers).

    • Passenger trains travels at higher speeds than freight and a doubling of speed will quadruple the aerodynamic drag.

    • Passenger train cars are heated or cooled (air conditioned) and lighted while freight cars are usually not.

  • Price it in - adsorb it from the oceans

    Archigeek wrote: Nucbuddy [...] I welcome your suggestions on how we can clean up the uranium mining and nuclear power industries.

    Why, thank you. I would suggest pricing in all externalities, and then letting the market decide. If terrestrial mining thus becomes too expensive, uranium (and thorium) can always be cheaply mined from the oceans.

    The consistent 3.3 ppb U in seawater is in chemical equilibrium. If it were being depleted, we would expect that additional U would be leached and put in solution from ocean bottoms, hydrothermal vents and cold seeps, and terrestrial sources (primarily through tidal pumping on the continental shelves, with some from rivers and other discharges). If we extracted a billion tons over hundreds of years, it is more likely that the oceans will contain nearly 4.5 billion tons than be reduced to 3.5+ billion tons.

    Is this a "renewable" energy source?

  • Pricy cars say, 'Use me, or you lost your money.'

    Biodiversivist wrote: Don't buy the theory that high mileage cars encourage more driving. A family swapping their 24 mpg Outback for a Prius would have to double the miles driven to get back to ground zero.

    Good point, for a given family, except:

    1. I think, that a Yaris or Corolla would be a more-likely Prius-competitor.

    2. There is no such thing as a 24-mpg Outback, since cars do not consume fuel. One owner uses 10 gallons in a year of Outback ownership. Another owner uses 10,000 gallons in a year of Outback ownership -- half the time idling it (zero miles travelled per fuel consumed). The quantity of miles-travelled, by itself, does not -- cannot -- matter. So far, no car has been marketed that pumps up its own tires, and certainly none that decides when/where/how it is used. An EPA-rating is just one among myriad factors, and in any one given case of any trend, N=1.

    3. An important point was the effect the fixed/marginal cost ratio has on average VMT and hours-used. When one pays a lot for an item, he feel compelled to get some return on his investment, and does socially-inefficient things like drive/sit-in/idle/use/wash/tinker-with his new car 1,000 hours in a single year. Automobiles are more expensive than they would be if they were made more like beige-box PC-clone computers. Features jack up the prices. Custom engineering (instead of universal component-modularity) jacks up the prices. CAFE and smog standards jack up the fleet-average prices, and the automakers also subsidize their fuel-sippers with extra-high prices on their guzzlers. Result: the guzzlers get driven/idled/used more, to make up for their high prices.

    If the Tato Nano were available in America for $2,500, Americans would have more financial opportunity to let their cars sit and rot, instead of feeling financially-compelled to use them constantly to ring out every last bit of value. Moving insurance-costs from fixed to marginal (per mile and/or per minute), would also help. Before you say something about status, perhaps part of the car-status issue is that Americans are resigned ahead-of-time to spending so much time in their cars, thus making the status of the car important. If one observes shoppers at nice-suburb supermarkets, one can observe lots of well-to-do people buying cheap food. They can get away with it, because no one sees their family eating it.

    No one sees the $1,000 brand-new gas-guzzing zero-safety-feature all-universal-modular-parts Model-T of the 21st-century rotting in the garage between being used 10 hours per year.

  • David: cars do not consume fuel

    I believe this article is essentially a repeat of another one that you ran a year ago. Yes, it is important to know. It is also important to know that not all cars are going to be driven the same distance, nor in the same manner, nor with the same maintenance regimen, nor in the same conditions. The average Prius owner only drives some 6-7 thousand miles per year (famous dust-to-dust study on Prius vs. Hummer), making his ownership of a Prius even more irrelevant than it would be if he drove a normal amount. Also, jacking up the fixed-costs of a car to cover features like fuel-efficiency and safety, merely makes the relative marginal-costs of driving drop -- encouraging more driving (and hence typically more fuel use), not less.


    Bottom line:

    Cars don't consume fuel. People consume fuel.

    Hull 2 Capacity Factor 23.3%.

    Interestingly, Hull 1 replaced a 1985 windmill that was destroyed in a storm in 1997. The capacity factor of that 1985 windmill, since 1997, has been 0%.

    Perhaps the four-turbine cluster of Hull 3 will indeed achieve a capacity factor of 33% -- in its first year. Then, salt, bugs, dirt, bird-parts, etc. might build up on the blades, reducing capacity-factor.

    Build-up of dead bugs has been shown to halve the maximum power generated by a wind turbine, reducing the average power generated by 25% and more. Build-up of salt on off-shore turbine blades similarly has been shown to reduce the power generated by 20%-30%.

    The machinery wears, especially in a salty environment, further reducing capacity-factor (Edmunds.com notes this, and thus reduces fuel-economy estimates over the five years of their total-cost-of-ownership estimates). The turbines might be taken offline for maintenance or repair.

    A `runaway event' at a 600 kW Nordtank wind turbine at Halling in eastern Jutland caused its blades to spin out of control and collide with the tower, causing the turbine to collapse. In an unrelated event at Vig in Odsherred, a 600 kW Vestas Wind Systems wind turbine lost a blade.
    [...]
    Failure to meet the requirements of a service certificate should result in a wind turbine being taken out of service.

    `It's very important that we act quickly, so Danes' confidence in wind turbines is not harmed,' said Bjarne Lundager Jensen, the association's managing director.


    Then, the turbines might be destroyed by a storm, before their planned decommissioning, just like the 1985 turbine that Hull 1 replaced, and just like myriad other might-still-be turbines worldwide that have suffered similar fates. It would be OK, though. The village of Hull could simply continue to draw on the natural-gas, coal, and nuclear power that it would normally be relying on anyway, even if/when all of its turbines were operational.

  • 40-trillion-tonne uranium supply - still cheap

    GRLCowan wrote: [Uranium] is of course clean, safe, and effective -- the very opposite of green. Per tonne, it now costs US$153,000 -- and replaces about $6 million in natural gas.

    The uranium spot price has been steadily dropping, and is now 18% lower:

    US$57.00/lb = US$125,400/tonne.

    The entire 40-trillion-tonnes Earth-crust supply -- 100 billion years' worth, at current nuclear-electric production rates -- of uranium can now be purchased for only US$5.016e18 (US$5 quintillion). If, in the future, prices were to rise to US$1 billion/tonne, and if we were to include thorium, the total Earth's crust supply of fission fuel would be worth US$.5 octillion.

    In 1987 the EPA classified DDT as a class B2 probable human carcinogen [...] Regarding the human carcinogenicity data, they stated "The existing epidemiological data are inadequate. Autopsy studies relating tissue levels of DDT to cancer incidence have yielded conflicting results."

    A study of malaria workers who handled DDT occupationally found an elevated risk of cancers of the liver and biliary tract. Another study has found a correlation between DDE and liver cancer in white men, but not for women or black men. An association between DDT exposure and pancreatic cancer has been demonstrated in a few studies, but other studies have found no association. Several studies have looked for associations between DDT and multiple myeloma, and testicular, prostate, endometrial, and colorectal cancers, but none conclusively demonstrated any association.

Triage would require that humans assign some quantification of priority to the preservation of a given ecosytem, so that it could be ranked against other quantified priorities. No one-given ecosystem is necessarily safe from triage, just as no one-given hospital-patient or R&D-effort is necessarily safe from triage.

    Humanity, through its continuous creation of new resources, might find itself wealthy-enough and ecosystem-valuing-enough to limit its enterprise to only small portions of the planet.


    Biodiversivist wrote: Hows that for intelligent?

    You didn't define intelligent, but doing things -- like preserving ecosystems -- for arbitrary reasons is the opposite of creative. Creativity is the resonation of order from disharmonious chaos. A bear acting choatically will tend not to achieve the harmonious order of a full belly, unlike a creative bear chewing through a backpacker's food-suspension line.

    google.com/search?q=cars+horses+manure+disease

    While the nineteenth century American city faced many forms of environmental pollution, none was as all encompassing as that produced by the horse. The most severe problem was that caused by horses defecating and urinating in the streets, but dead animals and noise pollution also produced serious annoyances and even health problems. The normal city horse produced between fifteen and thirty-five pounds of manure a day and about a quart of urine, usually distributed along the course of its route or deposited in the stable. While cities made sporadic attempts to keep the streets clean, the manure was everywhere, along the roadway, heaped in piles or next to stables, or ground up by the traffic and blown about by the wind. In 1818, in an attempt to control the manure nuisance, the New York City Council required that those who gathered and hauled manure, so-called "dirt carting," to be licensed, also restricting aliens to this type of carting activity. Thousands of loads of manure were gathered on special "manure-yards" to undergo a process of "rotting," and "gangs" of men were employed to overturn the manure and to expose it to weathering. In 1866, the Citizen's Association Report on the Sanitary Condition of the City observed that, "The stench arising from these accumulations of filth is intolerable."

    Nineteenth century urbanites considered the stench or miasmas produced by the manure piles a serious health hazard, but cleaning was sporadic at best. Manure piles also produced huge numbers of flies, in reality a much more serious vector for infectious diseases such as typhoid fever than odors. By the turn of the century public health officials had largely accepted the bacterial theory of disease and had identified the "queen of the dung-heap" or fly, as a major source. Inventors and city officials devised improved methods of street cleaning and street sweeping became a major urban expense. Increasingly, however, it became obvious that the most effective way to eliminate the "typhoid fly" (so named by L.O. Howard, chief of the Bureau of Entomology of the Department of Agriculture and a leader in the campaign against flies), was to eliminate the horse.

    Yes. More and more of those furnaces run on electricity.

    Electric arc furnaces (EAFs) produce more than a third of all raw steel output in the U.S. -- and that number is growing. Across the country, more and more ...

    The reason is that business runs on dollars. It does not care about thermal efficiency. It cares about economic efficiency.


    This is the opposite of the view expressed by Sean Casten, here:

    "That scheme is only efficient in terms of thermal-potential of the fuel."

    Is there another potential that matters? [...] We would be fools to use electric power to make heat
    [...]
    throwing heat away in cooling towers (regardless of the input fuel) is [...] flat out foolish. [...] we ought not throw away energy only so that someone else can burn more fuel
    [...]


    "Fuel is cheap. Human resources are expensive. Schemes to save fuel at the expense of human-resources are economically nonsensical."

    Not sure your point [...] When markets deploy capital [...] they universally chase energy efficiency.

    No, Sean.

A  tax on one's competition is also a latent subsidy for oneself. There is no intrinsic need to subsidize the low-carbon plants twice, Sean, by adding discrete subsidy to their existing latent subsidy. Either the latent-subsidy they receive is high-enough to allow them to compete, or the carbon-tax needs to be higher.

  • Nuclear power reduces total radioactivity

    Wolverine wrote: creating electricity from uranium causes more radioactivity to be emitted

    Actually, the opposite is true.
    phyast.pitt.edu/~blc/book/chapter12.html

    When uranium is mined out of the ground to make nuclear fuel, it is no longer there as a source of radon emission. This is a point which has not been recognized until recently because the radon that percolates out of the ground originates largely within 1 meter of the surface; anything coming from much farther down will decay away before reaching the surface. Since the great majority of uranium mined comes from depths well below 1 meter, the radon emanating from it was always viewed as harmless. The fallacy of this reasoning is that it ignores erosion. As the ground erodes away at a rate of 1 meter every 22,000 years, any uranium in it will eventually approach the surface, spending its 22,000 years in the top meter, where it will presumably do great damage. The magnitude of this damage is calculated in the Chapter 12 Appendix, where it is shown that mining uranium to fuel one large nuclear power plant for one year will eventually save 420 lives! This completely overshadows all other health impacts of the nuclear industry, making it one of the greatest lifesaving enterprises of all time if one adopts a very long-term viewpoint.

    If one wants less radiation in the world, then one might want nuclear power.

    That works out to a capacity-factor over 100%. Assuming 8,760 hours in a year, a capacity-factor of 95% would imply a 16.1 MW plant. A capacity-factor of 90% would imply a 17.0 MW plant. The cost quoted (that does not include the needed transmission lines) is $260 million. If we assume the plant is equivalent to a 17 MW baseload plant, that works out to $15,294/kWh.


    By the way, from the above link:

    [Walt Kuver, representing the Southern Nye County Conservation District, said,] "Renewable energy sounds like a good deal. Part of the renewable concerns, project concerns, is water consumption. Some solar power projects are sloppy and use a lot of water. We have to discourage that."

    Kuver explained water is used to cool the fluid going through the turbines powered by solar power to make electricity.

    Kuver talked about the difference between "dry cooling," which may use only 15 to 20 acre feet of water per year for a 100-megawatt plant, to "wet cooling," which could consume 1,200 to 1,500 acre feet. An acre foot of water is about 320,000 gallons, or enough water to supply two families for a year.

    Nevada Solar One near Boulder City uses 400 acre feet of water for 64 megawatts of power.

    Kuver said he expects protests to be filed by federal agencies on water applications for renewable energy projects in Amargosa Valley.

    The big renewable energy projects are in the middle of the Valley Electric Association service area, which Kuver said is "not a high-powered utility company."

There are transmission corridor issues," he said. "There are a whole host of things that have to be dealt with."

    Brian Brown, a member of the Amargosa Conservancy, mentioned massive solar and wind power projects are proposed in the Desert Southwest, with applications to use over 1 million acres of public land all the way to the Mexican border.

    "Now if you take 1 million acres of anything, and you remove all the plants, and you level it, and you cover it for tens of square miles, obviously that's going to have a significant impact on the environment and the whole ecosystem in that region," Brown told attendees at the workshop.
    [...]
    Some solar power facilities have significant water needs, while he said some green energy projects with massive wind turbines could mar the landscape.

    "Those have all sorts of implications, especially when you're talking about gigantic acreages. [...] Whenever you do a facility like this, you've got to get electricity into the grid so you've got to have transmission lines. You've got to have roads to maintain all this stuff. There are significant impacts of renewable energy."

    The cement industry is currently engaged in an aggressive $6 billion capacity expansion. More than 4 million metric tons of new clinker capacity is expected to come on-line this year. An additional 10 million metric tons of new clinker capacity is expected to come on-line during 2009. The capacity expansion coincides with the onset of an economic recession. Imbalances are expected to characterize the market during the next three years, resulting in elevated inventories, import reductions

    The potential supplies of all the important minerals are sufficient for many many lifetimes, on the basis of almost any assumption about these minerals' abundance on earth. This material-technical assessment is entirely consistent with the historical economic evidence of falling prices relative to wages for all raw materials, showing a trend of increasing availability and declining scarcity, as discussed in Chapters 1, 5, 8, 10, and 11.

    Since journalism's main currency is public trust, a reporter's failure to honestly acknowledge their sources undercuts a newspaper or television news show's integrity and undermines its credibility. Journalists accused of plagiarism are often suspended from their reporting tasks while the charges are being looked into by the news organization.

    The ease with which electronic text can be reproduced from online sources has lured a number of reporters into acts of plagiarism: Journalists have been caught "copying-and-pasting" articles and text from a number of websites.

"We think that in forty years time there will be no more ice at all on the North Pole after the summer. But, if we apply new calculations, it may well be from 2015 onwards.

  • A meltdown once a week is still safer than coal

    Bill McKibben wrote in the OP: Coal-fired power plants operating the way they're supposed to are, in global warming terms, as dangerous as nuclear plants melting down.

    How would a nuclear "plant" [perhaps you meant "reactor unit"] "melting down" be "dangerous"?
    phyast.pitt.edu/~blc/book/chapter6.html

    THE FEARSOME REACTOR MELTDOWN ACCIDENT
    [...]
    In 1978, a movie called "The China Syndrome" [...] gained widespread popularity. When the Three Mile Island accident followed in 1979, it became the news media story of the decade, complete with days of suspense during which the public was led to believe that a horrible disaster could occur at any moment. This combination of events led to very serious problems for the nuclear power industry.

    As a result of these developments, the word meltdown has become a household word. We will use it here, although it is no longer used by risk analysis scientists. In the mind of the public, it refers to an accident in which all of the fuel becomes so hot that it forms a molten mass which melts its way through the reactor vessel. Let's use the word in that sense. The media frequently referred to it as "the ultimate disaster," evoking images of stacks of dead bodies amid a devastated landscape, much like the aftermath of a nuclear bomb attack.

    On the other hand, the authors of the two principal reports on the Three Mile Island accident agree that even if there had been a complete meltdown in that reactor, there very probably would have been essentially no harm to human health and no environmental damage. I know of no technical reports that have claimed otherwise. Moreover, all scientific studies agree that in the great majority of meltdown accidents there would be no detectable effects on human health, immediately or in later years. According to the government estimate, a meltdown would have to occur every week or so somewhere in the United States before nuclear power would be as dangerous as coal burning.

    Even the Chernobyl accident, which was worse in many ways than any meltdown that can be envisioned for an American reactor, caused no injuries outside the plant. That is not to say that it is impossible to have fatalities caused by a meltdown, but it is estimated that in no more than 1 in a 100 meltdowns could any be obviously related to the accident.

We can insist that plants be subject to international inspection as a condition of sale or lease.

  • More on capacity factors - US-EPR over 94%

    The principal reason that Constellation assumes a high capacity-factor is that it has specified the US-EPR -- a reactor designed to achieve high capacity-factors:
    inspi.ufl.edu/icapp07/program/abstracts/7578.pdf

    The U.S. EPR is an evolutionary 1600 MW PWR design that represents the U.S. element of AREVA NP's global EPR fleet. Based on intensive R&D and the operating experience of nearly 100 nuclear power plants worldwide, the U.S. EPR embodies economical, state-of-the-art technology. One key focus of the U.S. EPR design is improved economic performance. Design features such as an enhanced online maintenance capability and simplified component design produce an average plant capacity factor in excess of 94% and scheduled refueling outages of less than 16 days.


    A 15-day refueling outage every 1.5 years would equal a 10-day refueling outage every year, which in turn would imply a capacity-factor of 355 / 365 = 97.3%. If that refueling outage were once per year, the capacity factor would be 350 / 365 = 95.9%. Adding a day (to make it a 16-day outage) makes that 349 / 365 = 95.6%.

    Constellation claimed it can expect an average capacity-factor of 95.3% (Slide 19), which is not only in the ballpark, but is on the conservative side. Doug Koplow seems to be wrong in regards to his statement (Slides 18 and 19) that Constellation's capacity-factor assumption "is aggressive".


    b

    GreyFlcn, the MIT, Keystone, and "Harding" studies are not directly relevant unless they are specifically, and only, examining the US-EPR -- a new, and explicitly high-capacity-factor, design.

    I think it would cost in the ballpark of one-tenth of a penny per kWh. It depends upon a number of factors, though, as Richard Garwin has pointed out. According to Garwin, the longer repository-space is delayed, the cheaper it is, since the thermal-power of the spent-fuel drops over time ("100 years [...] gives a further factor 10 decay"), and since capital is worth less in the future. With a century of delay, I would expect a repository to cost only one-hundredth of a penny per kWh.

    How could that be a subsidy, when the money would ultimately be coming solely from the nuclear-industry itself? Did you read the article you linked-to, GreyFlcn? It says, "If the repository opens in 2020, the damages would come to about $11 billion [...] and for each year beyond that, about $500 million more."

    About $30 billion is currently in the industry-paid-for spent-fuel-dispensation fund. 30 minus 11 leaves $19 billion left over. How could that be a subsidy? As for the $500 million per year (which is a high estimate) ongoing cost, the nuclear-industry currently pays $800 million per year into the fund. 800 minus 500 leaves $300 million. How could that be a subsidy?

    When money is being taken away from -- rather than given to -- an industry, GreyFlcn, that is not a subsidy. It is a tax.

  • Cuba: "post-oil" child-sex-slave utopia

    Jon Rynn wrote: Cuba is an interesting example of a society that has become post-oil, out of necessity, because they used to get all of their oil from the USSR -- no USSR, no oil.  So they instituted a program of urban gardens, cut down on car use, etc., and they are now doing quite well.

    There is more to the story of Cuba, Jon.
    cia.gov/library/publications/the-world-factbook/geos/cu.html

    [Cuba] is now slowly recovering from a severe economic downturn in 1990, following the withdrawal of former Soviet subsidies, worth $4 billion to $6 billion annually. [...] Illicit migration to the US - using homemade rafts, alien smugglers, air flights, or via the southwest border - is a continuing problem. The US Coast Guard intercepted 2,864 individuals attempting to cross the Straits of Florida in fiscal year 2006.

    If Cuba is "doing quite well", why are Cuban citizens trying to leave? Perhaps they know something about Cuba -- from actually having lived there -- that you do not.


    Economy - overview:
    [...]
    Since late 2000, Venezuela has been providing oil on preferential terms, and it currently supplies about 100,000 barrels per day of petroleum products. Cuba has been paying for the oil, in part, with the services of Cuban personnel in Venezuela, including some 20,000 medical professionals.

    If Cuba is post-oil, why is it lending out enslaved doctors in exchange for oil?


    GDP - composition by sector:  
    agriculture: 4.6%

    That would not be too bad, except that...

    Labor force - by occupation:  
    agriculture: 20%

    ...in light of the former figure indicates production inefficiency. Additionally, Cuba has $17 billion in debt, not including the $15-20 billion it owes Russia. Let's see how else Cuba feeds itself, and otherwise props up its economy:


    Transnational Issues
    Trafficking in persons:

    Cuba is a source country for women and children trafficked for the purposes of sexual exploitation and forced child labor; Cuba is a major destination for sex tourism, which largely caters to European, Canadian, and Latin American tourists and involves large numbers of minors; there are reports that Cuban women have been trafficked to Mexico for sexual exploitation; forced labor victims also include children coerced into working in commercial agriculture

    So, not only is one-fifth of the labor-force working in agriculture -- as opposed to less than one percent in the United States -- but in order to maintain output, Cuba uses agricultural slaves. Cuba does not seem to be interested in rectifying the slavery situation, either:

    tier rating: Tier 3 - Cuba does not fully comply with the minimum standards for the elimination of trafficking and is not making significant efforts to do so



    Now, did you not actually know these revealing things about Cuba, Jon, or were these the very types of things that you had in mind when stating that Cuba was "doing quite well"?

    en.wikipedia.org/wiki/Feed_conversion_rate

    In animal husbandry, feed conversion ratio (FCR), feed conversion rate, or feed conversion efficiency (FCE), is a measure of an animal's efficiency in converting feed mass into increased body mass.

    Specifically FCR is the mass of the food eaten divided by the body mass gain, all over a specified period of time. FCR is dimensionless, i.e. there are no measurement units associated with FCR.

    Animals that have a low FCR are considered efficient users of feed. Poultry usually can convert 2-3 kg of feed into 1 kg of live weight, while sheep and cattle need more than 8 kg of feed to put on 1 kg of live weight. The U.S. pork industry claims to have an FCR of 3.4-3.6.

    Uranium is a relatively common metal, found in rocks and seawater. Economic concentrations of it are not uncommon.
    [...]
    Since uranium is part of the energy sector, another way to look at exploration costs is on the basis of energy value. This allows comparisons with the energy investment cost for other energy fuels, especially fossil fuels which will have analogous costs related to the discovery of the resources. From numerous published sources, the finding costs of crude oil have averaged around US$ 6/bbl over at least the past three decades. When finding costs of the two fuels are expressed in terms of their contained energy value, oil, at US$ 1050/MJ of energy, is about 300 times more expensive to find than uranium, at US$ 3.4/MJ. Similarly, the proportion of current market prices that finding costs comprise are lower for uranium. Its finding costs make up only 2% of the recent spot price of US$ 30/lb ($78/kgU), while the oil finding costs are 12% of a recent spot price of US$ 50/bbl.

    By these measures, uranium is a very inexpensive energy source to replenish, as society has accepted far higher energy replacement costs to sustain oil resources.

    That is not true:

    For nuclear power plants any cost figures normally include spent fuel management, plant decommissioning and final waste disposal. These costs, while usually external for other technologies, are internal for nuclear power.

    Decommissioning costs are about 9-15% of the initial capital cost of a nuclear power plant. But when discounted, they contribute only a few percent to the investment cost and even less to the generation cost. In the USA they account for 0.1-0.2 cent/kWh, which is no more than 5% of the cost of the electricity produced.

    External radiation exposure and mortality in a cohort of French nuclear workers.

    [...]
    METHODS: A cohort of 29 204 workers employed between 1950 and 1994 at the French Atomic Energy Commission (Commissariat à l'Energie Atomique (CEA)) or at the General Company of Nuclear Fuel (COmpagnie GEnérale des MAtières nucléaires (Cogema, now Areva NC)) was followed up for an average of 17.8 years.
    [...]
    RESULTS: The mean exposure to X and gamma radiation was 8.3 mSv (16.9 mSv for exposed worker population). A total of 1842 deaths occurred between 1968 and 1994. A healthy worker effect was observed, the number of deaths in the cohort being 59% of the number expected from national mortality statistics. Among the 21 main cancer sites studied, a statistically significant excess was observed only for skin melanoma, and an excess of borderline statistical significance was observed for multiple myeloma. A dose-effect relationship was observed for leukaemia after exclusion of chronic lymphoid leukaemia (CLL). The relative risk observed for non-CLL leukaemia, n = 20, was 4.1 per 100 mSv (90% CI 1.4 to 12.2), linear model and 2.2 per 100 mSv (90% CI 1.2 to 3.3), log-linear model. Significant dose-effect relationship were also observed for causes of deaths associated with alcohol consumption: mouth and pharynx cancer, cirrhosis and alcoholic psychosis and external causes of death.
    [...]
    CONCLUSION: The risk of leukaemia increases with increasing exposure to external radiation; this is consistent with published results on other nuclear workers cohorts.

As soon as industry finds what it needs for the immediate future, it stops exploring. However, we know that finding more "reasonably assured reserves" at any time would easy, since uranium exploration is inexpensive in relation to oil exploration.

    Manacker wrote: it will take new technology to recover uranium from [the world's estimated total uranium available from all sources] at an economically viable price. Have I got this right?

    No.

    Please try reading the links again. Uranium mining is economically viable down to 1ppm -- which would provide an energy-return factor of 1.6, scaling current operations at the Rossing mine in Nambia -- using current technology. Therefore, current technology alone gives us an economically-viable uranium resource of 40 trillion tons. At an energy value that would put oil at $100, one kilogram of uranium is worth $1 million, and an average square meter of the earth's continental crust is worth $1 billion -- equal to a layer of pure solid gold, 6 feet thick -- just for the uranium and thorium it contains. Yet, mined uranium is sold today for only $20-$200/kg.

    The price of mined-uranium could rise by more than a thousand-fold, and mined-uranium would still be economically viable.


    Manacker wrote: there is potential new nuclear fusion technology.  What do you think of this as a long term alternate?

    Technologies are easier to develop, the greater the power-consumption of society. If fission-energy is continuously ramped-up at a rate of 10-trillion-fold-per-millennium (3.04% per year), fusion should be fairly easy to develop 4 or 5 centuries from now. There would be no need for fusion until then, and it probably would not be competitive until then. Any present directing-of-resources to fusion research is therefore irresponsible.

    If the energy-consumption-growth of Earth-based civilisation levels off several centuries from now, then there will be no need for fusion energy for several thousands or millions of years.


    Manacker wrote: The report say that the development of these new technologies would "provide enough fuel for many centuries of energy production".  You mentioned a "trillion years"; maybe it's only a "billion", but who cares?  It's a long, long time.You mentioned a "trillion years"; maybe it's only a "billion", but who cares?  It's a long, long time.

    The total amount of the resource matters, even if it seems to be very large, when considering an exponentially-evolving energy scenario. I calculated that the 200 trillion tons of currently-economically-viable uranium and thorium in the earth's crust would fuel our current nuclear-electric power level for half a trillion years (or a full trillion years, if we use Bill Hannihan's figures). If civilization ramps up its power-consumption at a rate of 20-fold-per-century (3.04% per year), then that same 200-trillion-ton resource will last only half a millennium.


    Manacker wrote: fast breeder reactors

    These have no relevance for the present century, and little relevance several centuries into an exponentially-evolving energy-consumption scenario. If and when they are needed, it will be apparent enough. They will also be easy to develop at that time, since (as will be the case with fusion) resources needed for such development will be far more available. As is the case with regards to fusion, direction of resources toward the development of breeder reactors any time in the present century is, and would be, irresponsible.


    Manacker wrote: It shows that there is a lot of R+D work going on today worldwide to develop more efficient reactors

    Such R+D work is irrelevant. What needs to be currently researched is how to get rid of the Nuclear Regulatory Commission (NRC). If not for the NRC, nuclear reactors would be as ubiquitous, and evolve as fast, as automobiles.

    Largely reliant does not mean absolutely reliant, so your statement might be taken to imply that plants are not absolutely reliant upon rainfall, and fair weather. Even if plants were the basis of food production, if plants were also indeed not absolutely reliant upon rainfall, and fair weather, how could there be a connection between hunger and global warming?


    GreyFlcn wrote: SeaFood makes up a gigantic portion of the protein provided to the world's populace.

    Wikipedia says:

    Fish [...] with other seafoods [...] provides [...] 14-16% of the animal protein consumed world-wide; over 1 billion people rely on fish as their primary source of animal protein.

    Those proportions do not seem overwhelming to me, so I would take that Wikipedia statement to mean that seafood could be entirely deleted from the worldwide human diet with little even-immediate overall effect on hunger. However, even if seafood accounted for 100% of human dietary protein, and if global-warming were capable of -- and likely to -- wipe out seafood stocks, that would still not provide a basis for a connection between hunger and global-warming. The reason for that is that humans (unlike other creatures) create their own resources, and -- in sufficiently-liberal economies -- humans sufficiently renew, or create-substitutes-for, resources undergoing depletion. If seafood is not yet being substituted-for, it would theoretically be at least because of either economic illiberalism or because seafood is not yet expensive-enough.

    Which would it be? Is the economy too illiberal?

  • The excellent efficiencies of modern powerplants

    Sean Casten wrote: Electric power generation [...] is 1/2 as efficient as it was in 1910.

    That is true, neither in terms of thermal efficiency, nor in terms of economic efficiency.

    Edison's New York City plant [...] converted about 2.5% of the energy from fossil fuel into electricity. That number rose to 4% in 1900 and 10% in 1913 in Insull's advanced power plants. The trend continued into the 1960s, when the industry's best power unit converted about 40% of the raw energy into electricity; the average plant demonstrated an efficiency of a few percent less--33%.

    From the same link:

    Consumption of power grew at a 12% annual rate from 1900 to 1920; from 1920 to 1965, it leaped ahead at about 7% per year. Such rapid rates of electricity consumption exceeded the growth rate for all energy sources together by a factor of 4 to 5.5 times. As consumption increased, the price of power declined: in 1965 cents, power used by residential customers dropped from about 90 cents per kWh in 1892 to a little more than 2 cents in 1965.

    In current dollars, that would be $6.02/kWh in 1892, and "a little more than" $0.13/kWh in 1965. Looking at the graph, it seems to have been a nominal $0.10/kWh in 1910, which would be $2.24/kWh in current dollars.

    The value of thermal energy continuously declined throughout the 20th century, as this quote indicates:

    The major reason for the rapid escalation of consumption was simply that electricity proved to be a highly versatile source of energy that was highly valued in American society. [...] In general, electricity became viewed by most people to be a commodity that made life more pleasant and more productive. "Live better electrically"--an advertising slogan employed by the utility industry in the late 1950s-- should not be viewed cynically as an advertising pitch from selfish hucksters. Rather, it reflected a generally accepted truth about the value of electricity. In this light, one can understand why most utility managers took special pleasure in their work. Not only did they help their companies produce more power at lower rates; they also helped improve the lives of their customers.

    Therefore, also in this light, we can see that alternate efficiency-comparisons based upon mere employment (rather than employment specifically to generate electricity) of thermal-power-generated are highly irrelevant -- and increasingly-so.On Nukes don't replace oil posted 1 year, 10 months ago 39 Responses

    Today there are hundreds of potential terrorist targets in the form of dams located in densely populated areas. Attacks and even suicide-attacks from the dam itself or from a watercraft would eliminate the need for aircraft. All that would be required would be a relatively small amount of explosives dropped on the back of a dam in a water tight container. Major dams, especially iconic ones like the Hoover dam have security measures and are monitored, but many smaller structures are entirely unguarded and have only the most minimal security.

    Helicopter goes down in central NY, 4 suffer minor injuries
    Associated Press - January 15, 2008 6:35 PM ET

    FENNER, N.Y. (AP) - Four people suffered minor injuries when their company helicopter crashed near a windmill in central New York.

    A state trooper says all four aboard the helicopter were able to walk away from the aircraft after it made what appears to have been a hard landing near a windmill farm in Fenner in Madison County.

    The private helicopter was owned by Adkins Aviation of Cornelius (North Carolina), although company officials could not immediately confirm it was 1 of their aircraft. Initially, state police believed the helicopter was owned by Canastota Windpower, which owns the 20-turbine wind farm located 30 miles east of Syracuse.

    The helicopter crew was doing routine maintenance when the pilot became disoriented in the heavy fog. It's not known what caused the accident.


    The principal reason that windpower involves such an extremely high number of per-kWh accidents, injuries and fatalities is that it taps a relatively diffuse power source. The safest power sources, such as coal and especially nuclear, have high energy density -- again, particularly nuclear has the highest energy density. The most-dangerous power sources, such as windpower, hydro and solar, have low energy density.On Draft EIS for Nantucket Sound wind project is positive posted 1 year, 10 months ago 35 Responses

  • A look at what other blogs say about C. Castro

    http://antigreen.blogspot.com/2008/01/climate-change-blam ...

    your citation of Prof. Andrew Dessler's articles at Grist is amusing. Dessler has monumentally embarrassed himself by recently claiming there were only two dozen scientists skeptical of man-made climate fears. Dessler is now trying desperately to salvage his unsupportable assertions over at Grist with increasingly shrill and comical posts.

    It is made clear you have not read the Senate report when you parrot Dessler's claims that Dr. Christopher Castro "unabashedly and explicitly endorses the IPCC consensus." If you took the time to read Castro's entry in the Senate report you would find that even though he accepts the idea that mankind is responsible for most of the recent warming, he has serious doubts about future dire predictions of warming. Excerpt from report:

    Castro, who studied under skeptical climatologist Dr. Roger Pielke, Sr. "agrees that `other possible forcings to the climate system besides CO2 (like land-use change, aerosols, etc.) are not accounted for well, if at all' and "models are highly sensitive to parameterized processes, like clouds, convection, and radiation, and these processes can have significant impacts on their results.'"

    Remember, many skeptical scientists believe the Earth has already seen most of the warming impact of rising CO2, so agreeing that a 20th century CO2 rise has caused some warming is not the same as believing future catastrophic climate projections.

    The Alliance leader said his consulting work for Clipper Windpower, which assembles 2.5 megawatt turbines at its Iowa plant, was in no way ironic.

    "I am very much committed to all of these technologies being used in the right ways," he said. "We would work even with Jim Gordon to find sites outside of Nantucket Sound."

  • Yes, it is indeed BYD (plug-in hybrid F6 sedan)

    http://online.wsj.com/article/SB120005753514983735.html?m ...

    [Paul Lin, auto export manager of BYD Auto] [...] said his company wants to launch in the U.S., among other vehicles, a new breed of a gasoline-electric hybrid that can be plugged into a home wall outlet and run 100 kilometers (about 61 miles) on electricity when fully charged.

    Mr. Lin said the plug-in hybrid, based on its gasoline-fueled BYD F6 sedan, will likely hit U.S. dealer showrooms until the end of 2009 or the beginning of 2010. BYD Auto is expected to display the plug-in hybrid at the North American International Auto Show that opens to the public on Jan. 19.
    [...]
    He said the launch of the plug-in hybrid would be quickly followed by other models including other plug-in hybrids, all-electric cars, as well as conventional gasoline-fueled vehicles. Mr. Lin didn't elaborate on what kind of time frame BYD Auto had in mind.

    Mr. Lin said the plug-in hybrid is almost ready for sale in China, but BYD Auto will need at least two more years to make sure it meets America's tough safety and other regulations.

    In China, Mr. Lin said BYD Auto plans to launch the plug-in hybrid this summer -- "during the Beijing Olympics" -- and is likely to sell it for 200,000 yuan [$27,542.50 USD].
    [...]
    The car would likely to sell for a similar retail price tag in the U.S., he said.

    The BYD plug-in hybrid, to be called the BYD F6 DM, is similar in design to General Motors Corp.'s Chevy Volt concept car which GM is aiming to launch by 2010. Both cars are propelled by electric motors using electricity stored on batteries and generated by a small gasoline engine on the car when the car run out of electricity when it isn't plugged in.

    BYD Auto, which began producing and selling cars in 2003, is displaying the plug-in hybrid car and four gasoline-fueled vehicles at the Detroit auto show.

    Meanwhile, a single nuclear powerplant could supply all of the electricity in the U.S. in less than a single square mile. One difference between the solar plant and the nuke would be that the nuke would not be restricted to the Mohave Desert.

    Original Post wrote: "This is a serious attempt to reduce bunker [fuel] costs and polluting emissions,"

    No, this is:

    With nuclear ships, fuel expenditures are minor, both in terms of weight and cost. At current nuclear fuel prices an SHP hour produced by fissioning slightly enriched uranium fuel costs less than one sixth as much as an SHP hour produced by burning residual oil. The advantage is even more dramatic when compared to distillate fuels. There is virtually no change in weight on a nuclear powered ship because of fuel consumption.

    There are obvious advantages to increased speed if fuel consumption is less constraining. More cargo can be moved with the same number of ships. Cargo will spend less time at sea and more time where it is needed. Shippers will pay higher rates for certain types of cargo since they will save on financial carrying costs. Since a faster ship requires the same crew size as a slow one, productivity can increase be improved without painful layoffs.

  • The sales numbers tell what people value

    Odograph,

    The pundit-chosen "equivalent" cars are equivalent in terms of what people generally value. Why are you telling others that what they should value should be based upon your personal hobbies?

    Let's let the numbers speak for themselves:
    http://12.155.133.84/autos/reviews/review.aspx?ID=814

    The Chevrolet Tahoe competes in the Large Utility segment, which consists of eight models. Buyers in this segment look for comfort, performance, and exterior styling, according to the J.D. Power and Associates 2006 Avoider Study and the Escaped Shopper Study.

    The top sellers in the segment during calendar year 2006, according to the J.D. Power and Associates Sales Report, were the Chevrolet Tahoe (161,491 units sold), Ford Expedition (78,953), and Chevrolet Suburban (77,211). The Chevrolet Tahoe's 161,491 sales in 2006 represent an increase of 6.0 percent compared to the previous year. Other models offered in the Large Utility segment include the GMC Yukon and Yukon XL, Toyota Sequoia, and Nissan Armada. Joining the segment in 2007 is the Ford Expedition EL.

    There it is in black and white, Odograph: "comfort, performance, and exterior styling". Fuel-economy is notably absent. Why are you telling others that what they value should be based upon what you personally value? Over about 10 or 20 mpg, why would anyone, except for an odd bigot here or there, care about fuel-economy?

  • Windmills continuously draw power from the grid

    Sam Wells wrote: power is required to turn wind turbine blades when the wind is slow

    Yes, it is.
    aweo.org/windbackup.html

    the turbines use a great deal of electricity themselves. Most of them cannot even run without input from the grid. Although they produce electricity intermittently, they consume it continuously. In every report I've seen, input from the grid is not accounted for in the figures of net output. Specifications from turbine manufacturers do not include the amount of electricity they require.

    It may be that large wind turbines use as much electricity as they produce. Whether the wind is blowing in the desired range or not, they need power to keep the generator magnetized, to keep the blade and generator assembly (92 tons on a 1.5-MW GE) facing the wind, to periodically spin that assembly to unwind the cables in the tower, to heat the blades in icy conditions, to start the blades turning when the wind is just getting fast enough to keep them going, to keep the blades pitched to spin at a regular rate, and to run the lights and internal control and communication systems.

    Discrete energy-efficiency and diffuse-power types such as wind and solar tend to decrease the new-value/work ratio -- by doing so, they tend to increase human slavery.

    Averaging according to a harmonic mean method (which basically means averaging the reciprocals) accomodates for the potential averaging-problem you pointed-out in your comment.


    GreenEngineer wrote: If you have one car that gets 20 MPG and one that get 60 MPG, your CAFE is 40 MPG.

    No, the CAFE harmonic-mean method would say that you have a CAFE of 30 mpg. The CAFE harmonic-mean method would not add 20 mpg to 60 mpg and then divide by two. It would divide 1 by 20, add that to (1 divided by 60), and divide 2 by that sum. The result would be an average 30 mpg, which would equal a summed gasoline usage for both vehicles of 667 gallons over 10,000 miles -- exactly as you calculated it should be.

    In comparison, two 40 mpg vehicle would indeed be calculated at an average of 40 mpg and together would use only 500 gallons of gasoline over 10,000 miles.

    Therefore, the CAFE methodology -- because it calculates according to a harmonic-mean -- does indeed recognize the superior fuel-economy of two 40 mpg vehicles vs. one 20 mpg vehicle summed with one 60 mpg vehicle.

    Developer cites cost in nixing offshore wind farm in South Texas
    [...]
    Plans to build what would have been the nation's largest offshore wind farm in South Texas have been called off because the multibillion-dollar project didn't make economic sense, the developer said Monday.

    John Calaway, chief development officer for Babcock & Brown Ltd., the Australian investment bank, said the company notified the state a month ago it was giving up its 30-year lease on nearly 40,000 acres in the Gulf of Mexico off the coast of Padre Island.
    [...]
    ``We just don't see the economics working offshore in Texas,'' Calaway said, noting the project cost would have been ``in the billions.''

    He said offshore wind farms on the East Coast, such as a proposed project off the coast of Massachusetts, are more logical and potentially viable because of land constraints and higher energy prices in the region.

    The now-defunct Texas project called for construction of about 170 turbines, each 400 feet tall, with the capacity to generate 500 megawatts of energy -- enough to power about 125,000 homes.

    Babcock is moving on with an onshore wind farm in South Texas' Kenedy County, a $700 million-plus venture that calls for 157 turbines on thousands of acres, Calaway said. He noted the expense of building an offshore farm can be more than double the cost of one on land.

    ISCOR Mining, South Africa - 1982 to 2001

    ISCOR is presently the largest user of trolley assist in the world. These photos are primarily of the "early" ISCOR trolley system, with the exception of those showing the Euclid R280 AC truck. ISCOR has perfected a "lightweight" overhead line system, which is fed by many small substations. It is hoped to add photos of the current system in the near future.

    As of February 2001, the Sishen mine was operating a trolley haulage fleet consisting of 32 Komatsu 730Es and 9 Unit Rig M36s. The Grootegeluk mine was operating a trolley haulage fleet consisting of 14 Komatsu 730Es, 11 Marathon-LeTourneau 2200s, and 1 Euclid R280 AC.

    Barrick Goldstrike - 1994 to 2001

    Barrick conducted numerous trolley feasibility studies and in 1993 gave the go-ahead to proceed with the installation of a system at their Goldstrike mine in Nevada. The system was patterned after Palabora's, except that the equipment was upsized to accommodate Goldstrike's larger trucks (190 ton vs. 170 ton).

    Overhead lines and substations were supplied by Siemens, and were of a full-catenary heavy-duty design. Pantographs, from TransTech of South Carolina, were used for current collection. Their "half-scissor" design differed from the "full-scissor" design used at Palabora.

    By October 1994 five trolley lines, which totaled 2.9 miles in length, were in service - along with 50 Komatsu 685E haul trucks that had been converted for trolley operation. Barrick continued to expand the trolley system, with a total of 74 trucks and 4.5 miles of trolley lines in service.

  • Instant power-modulation means batteries and shunt

    Sean Casten,

    Before, you said it was aggregation that gave the grid its advantage. I pointed out that you neglected to mention the lead-acid batteries and the resistive shunts that make the grid function smoothly so that when you flip a lightswitch on, you have instant power, and when you flip a lightswitch off, nothing blows up or catches on fire. If you want that level of modulation-ability, aggregation won't cut it.

    You are still neglecting to mention the lead-acid batteries and the resistive shunts that make the grid function so smoothly.

    ...And it isn't energy we can modulate instantly from the grid, it is power.


    Sean Casten wrote: we shouldn't lose sight of how much better this is than life before the grid, when getting more power meant going out and firing up another generator

    Before the grid, instant power modulation meant relying on lead-acid batteries and resistive shunts -- the same as today.

    You do not actually believe this, do you? Are you aware that electrical generating stations employ lead-acid backup batteries and resistive shunts to even-out the power? If you install a windmill on your property and tie it to the grid, where do you suppose the power goes when the wind happens to blow? Typically, it gets bled off by a resistive shunt -- i.e. the electrical utility, after being forced to buy it from you, disposes of your garbage-power for you.

  • Toshiba's nuclear-fig-leaf eliminators

    Amazingdrx wrote:

    wars over nuclear proliferation could be halted by deploying renewable energy

    Please explain how that high-risk option would work, and how the low-risk option of Toshiba et al deploying these dozens of different models of nuclear-fig-leaf eliminators would not work.

    Japan's LSPR is a lead-bismuth cooled reactor of 150 MWt /53 MWe. Fuelled units would be supplied from a factory and operate for 30 years, then be returned. Concept intended for developing countries.

    A small-scale design developed by Toshiba Corporation in cooperation with Japan's Central Research Institute of Electric Power Industry (CRIEPI) and funded by the Japan Atomic Energy Research Institute (JAERI) is the 5 MWt, 200 kWe Rapid-L, using lithium-6 (a liquid neutron poison) as control medium. It would have 2700 fuel pins of 40-50% enriched uranium nitride with 2600°C melting point integrated into a disposable cartridge. The reactivity control system is passive, using lithium expansion modules (LEM) which give burnup compensation, partial load operation as well as negative reactivity feedback. As the reactor temperature rises, the lithium expands into the core, displacing an inert gas. Other kinds of lithium modules, also integrated into the fuel cartridge, shut down and start up the reactor. Cooling is by molten sodium, and with the LEM control system, reactor power is proportional to primary coolant flow rate. Refuelling would be every 10 years in an inert gas environment. Operation would require no skill, due to the inherent safety design features. The whole plant would be about 6.5 metres high and 2 metres diameter.

    The Super-Safe, Small & Simple - 4S 'nuclear battery' system is being developed by Toshiba and CRIEPI in Japan in collaboration with STAR work in USA. It uses sodium as coolant (with electromagnetic pumps) and has passive safety features, notably negative temperature and void reactivity. The whole unit would be factory-built, transported to site, installed below ground level, and would drive a steam cycle. It is capable of three decades of continuous operation without refuelling. Metallic fuel (169 pins 10mm diameter) is uranium-zirconium enriched to less than 20% or U-Pu-Zr alloy with 24% Pu for the 10 MWe version or 11.5% Pu for the 50 MWe version. Steady power output over the core lifetime is achieved by progressively moving upwards an annular reflector around the slender core (0.68m diameter, 2m high in the 10 MWe version, 1.2m diameter and 2.5m high in the 50 MWe version) at about one millimetre per week. After 14 years a neutron absorber at the centre of the core is removed and the reflector repeats its slow movement up the core for 16 more years. In the event of power loss the reflector falls to the bottom of the reactor vessel, slowing the reaction, and external air circulation gives decay heat removal. A further safety device is a neutron absorber rod which can drop into the core. After 30 years the fuel would be allowed to cool for a year, then it would be removed and shipped for storage or disposal.

    Both 10 MWe and 50 MWe versions of 4S are designed to automatically maintain an outlet coolant temperature of 510?C - suitable for power generation with high temperature electrolytic hydrogen production. Plant cost is projected at US$ 2500/kW and power cost 5-7 cents/kWh for the small unit - very competitive with diesel in many locations. The design has gained considerable support in Alaska and toward the end of 2004 the town of Galena granted initial approval for Toshiba to build a 4S reactor in that remote location. A pre-application NRC review is under way with a view to application for design certification in 2009 and construction and operating (COL) application about 2012. Its design is sufficiently similar to PRISM - GE's modular 150 MWe liquid metal-cooled inherently-safe reactor which went part-way through US NRC approval process for it to have good prospects of licensing.

  • Vehicle platooning - saves energy, saves time

    tech-faq.com/vehicle-platooning.shtml

    Vehicle Platooning


    Maximizes Highway Throughput

    Vehicle platooning makes it possible for vehicles to travel together closely yet safely. This leads to a reduction in the amount of space used by a number of vehicles on a highway. Thus more vehicles can use the highway without traffic congestion.

    In fact, it has been estimated that at a fixed separation of 21 feet between vehicles traveling at 65 miles/hour, highway vehicle capacity increases from the regular 2000 vehicles per lane/hour to 5700 vehicles per lane/hour. Even with an increase of 25% in the separation between vehicles to allow for maneuvers and a 200 ft separation between different vehicle platoons, the highway vehicle capacity will still be 4300 vehicles per lane/hour - more than double the normal capacity.


    Reduces Drag

    It has also been observed that vehicle platooning significantly reduces the drag that each vehicle experiences. This reduction of drag translates into less fuel consumption, greater fuel efficiency and less pollution. Drag reduction is found out to be most effective when the distance between vehicles in the platoon is half the car length; at this distance, there's 50% reduction in drag and 20-25 percent reduction in fuel consumption.
    [...]


    How Vehicle Platooning Works

    Vehicle platooning makes use of different technologies to achieve safe and efficient transport. From radars to magnets to radio communication systems, vehicle platooning systems have been found to be more efficient than most human drivers.

    World liquids consumption in the IEO2007 reference case increases from 83 million barrels per day in 2004 to 118 million barrels per day in 2030. Two-thirds of the increment is projected for use in the transportation sector.

    My guess is that oil consumption is going to continue ramping-up for at least the next century. Over the same time period -- because only a tiny fraction of the total petroleum resources have been so-far tapped, and because tapping efficiency is bound to continue to improve -- prices will steadily fall beyond historic lows.


    Jon Rynn wrote: peak oil, we should be ramping down consumption of fossil fuels.

    If there is a collective-interest in reducing present oil demand in anticipation of future supply-shortages, that can be resolved by decriminalizing (eliminating taxes on) futures-trading. By anticipating the profitability of future shortages, futures-traders can cause the present prices of oil to rise, thereby reducing present demand and further-thereby resolving future oil shocks.

  • Denmark knows the true cost of wind-power

    Amazingdrx wrote: I assume that is a bid to provide wind power at 4.5 cents per kwh. [...] That puts the real cost of wind well below 4.5 cents.

    Meanwhile, electricity prices in Denmark average around 30 cents per kWh.
    cphpost.dk/get/103869.html

    `During the course of a day, energy prices can swing by as much as 50 percent,' said Ebbe Seligmann, Syd Energi's managing director. `When the currents are cheapest a kilowatt costs around DKK 1.20, while it costs around DKK 1.80 at its most expensive.'

    DKK 1.20/kWh = USD $0.23/kWh
    DKK 1.80/kWh = USD $0.35/kWh

    x-rates.com/calculator.html


    It is expected that if more wind were installed in Denmark, electricity prices would rise even further.
    cphpost.dk/get/100287.html

    The government's plan to increase the nation's reliance on green power could expand a black hole that already sucks two billion kroner out of consumers' pockets annually.

    To promote construction of wind turbines, the state has agreed to purchase the electricity they generate at a minimum price. The guaranteed has had the desired effect: 5300 wind turbines dot the Danish countryside, producing 18.5 percent of all electricity generated.

    The practice has its downside, however. The guarantee prices for wind power results in an overproduction that costs the state DKK 21.6 billion between 2001 and 2005, according to figures from the National Audit Agency.

    Uncertainty over whether the wind will blow means Energinet.dk, the organisation responsible for ensuring that the country can meet its electricity demand, has to keep a reserve of conventionally produced electricity. That cost is typically passed on to consumers in the form of higher electric bills.

    Maintaining that safety net results in a near constant overproduction of electricity, reducing wind power's share of the total amount used to power Danish homes and factories to 8.3 percent. The unneeded electricity is exported, at a lower price than that paid to windmill owners.

    In 2005, the loss amounted to DKK 1.7 billion, according to the National Energy Authority.

    By 2025, the government expects to increase renewables' share of the power supply to 30 percent. By then wind turbines are projected to contribute three times as much energy as they do now, accounting for 60 percent of all power generated in Denmark.

    Relying more on renewables will help the nation meet its CO2 emission obligations, but the green ambitions could prove costly, with some calculations putting the economic costs of the package at DKK 5.2 billion annually.

    During the presentation of the plan earlier this month Energy Minister Flemming Hansen said the price was one the government was willing to pay: `We don't know how much this is going to add up to, but we are willing to pay it, no matter the cost.'

    Energinet.dk expects to invest DKK 3.4 billion to connect new wind turbines to the power grid, with consumers again likely to foot the bill.

    `Right now it's difficult to put a price tag on this, but it will be something electricity users will notice,' said Energinet.dk chief executive Peder Ø Andreasen.

    Ditto, as long as you can find a tow hitch for an older Yaris. The only economic reason to prefer new over used is if you are planning on putting on substantially-more mileage than the new-vehicle fleet average of 15,000 miles per year. (My personal cutoff would be something like 20,000+ miles per year.) Used cars can be purchased online on eBay, Auto-Trader, etc.

    By the way, you can put a hitch on a Chevy Aveo, and it is a far better value than a Toyota Yaris (especially considering the fact that Toyota's quality ratings have been dropping like rocks).

    That works out to $2,250/kW -- and if the Cliffside expansion project involved two 800 megawatt units, instead of just one, the price per kilowatt of capacity would undoubtedly be lower.


    Sean Casten wrote: I recently heard that their $2500 number doesn't include the construction finance costs, which they clearly have to pay.  Add those in, and they've topped $3000.)

    That is an absurd assertion. Capital cost figures are capital cost figures. Finance costs are never included in capital cost figures, unless noted.

    The hit from the above-search notes, "[the 800-megawatt coal unit] would cost $1.8 billion for construction and about $600 million to finance. Finance costs would therefore push it up to $3,000/kW. However, finance costs are not capital costs -- they are separate figures.


    Sean Casten wrote: while you are generally right that the published reports coming in right now are in the $2000 - $2500 range

    I did not say that. Please stop raping me. A single 800-megawatt coal-fired unit has been quoted at $2,250/kW. A larger powerplant would undoubtedly benefit from economy of scale, and would therefore be less-expensive per unit of capacity.

    Worldwide, levelized lifetime wholesale coal-electric costs (including capital and operating costs) tend to be competitive with those of gas and nuclear. A summary of a diverse array of studies and examples is available here:
    world-nuclear.org/info/inf02.html

    For the United States, new coal is consistently found to be less-expensive than new gas. This map (made March 2007) shows that the U.S. states that produce more of their power from coal, tend to have lower electricity costs. The typical exceptions are the hydropower states, such as Washington, Oregon, and Idaho. The rule seems to be: if you want cheap electricity, you want coal or hydro.

    Residents may reap windmill compensation
    02.08.2007 [August 2, 2007]

    Stalled plans to build new high-efficiency wind turbines could get a jump start thanks to a government plan to pay residents for decreased property values.

    Property owner resistance over plans to replace the country's 5000 existing wind turbines with fewer high-efficiency models has the government suggesting that homeowners living in the shadow of the 150-metre giants be compensated for lost property value.

    Most politicians and citizens are in agreement that wind power is the way to a cleaner, more environmentally friendly future, but many also believe rows of wind turbines are an eyesore and destroy the harmony of the nation's gentle landscape.

    The new initiative to compensate property owners comes on the heels of a report from a special commission created by parliament to determine the most aesthetic means of erecting new wind turbines across the country.
    [...]
    citizens' groups concerned about the effects the new wind turbines have on the landscape have managed to stall the process. Connie Hedegaard, the environment minister, believes the new initiative will help get it back underway.

    'If you live near a new wind turbine, you should be able to receive compensation from the state,' she told Weekendavisen newspaper.
    [...]
    'I still think it's best to discuss the situation out in the communities,' she said. 'There are cultural lines in the landscape that you can't necessarily see just by looking at a map.'

    When wind turbines began to sprout up in earnest at the beginning of the decade Uffe Ellemann-Jensen, the former leader of the prime minister's Liberal Party, expressed the feelings of many when he called wind turbines 'politically correct, economically questionable and ugly'.

    Summertime solar heat is cheaper than petroleum heat. However, no one uses petroleum for heat in the summertime. The few people who do use it for heat at all do so in the wintertime -- precisely when the sun does not shine. In fact, the lack of sunshine in the winter is the reason that winters are cold in the first place, and hence the need for wintertime artificial-heating.

    People do use electricity for heating in the wintertime. They use it directly through resistance-heaters, and they use it indirectly via air- or - ground- source heat-pumps. As noted above, things that make electricity include coal, natural gas, nuclear and hydro powerplants.

    Flood of New Nuclear Reactors Expected
    By DUNCAN MANSFIELD - 1 day ago

    CHATTANOOGA, Tenn. (AP) -- Federal regulators, girding for explosive growth in the nuclear power industry, say they are weeks away from an anticipated flood of license applications for new reactors not seen since the 1970s.
    [...]
    The independent regulatory agency expects to receive new fast-tracked combined construction and operating license applications for as many as 29 reactors at 20 sites, most in the South, over the next three years.

    The first could come as early as Oct. 1, the start of the federal fiscal year.

    "We have never had to do this many reviews at one time in parallel with an office that has only existed for less than 12 months," Borchardt said Thursday at the NRC's reactor training center in Chattanooga.

    "Nobody thinks this is going to be easy."

    Borchardt has hired more than 400 inspectors, engineers and examiners to handle the load.
    [...]
    to keep reactors on the fast track, most will incorporate modular construction with large parts -- the reactor vessel, for instance -- made in other locations, such as Japan. Some large components already are being ordered, Borchardt said.

    Using standardized design and modular construction "allows General Electric to (be able) to claim that they can construct from first concrete to reactor critical -- an entire power plant -- in approximately 36 months," NRC reactor technology instructor Richard DeVercelly said.

    That's about how long it took to build two new reactors in Japan that use an advanced boiling-water design that the NRC has certified for U.S. power companies, he said.

    By comparison, TVA took five years alone to rebuild and restart its oldest reactor at the Browns Ferry station in Alabama, which returned to service this year.

    "It is pretty clear that the plants will be built more rapidly (and) are going to make extensive use of modular construction," Borchardt said. "One of the great lessons from the 1960s and 1970s is that you do a much better job if you can design them before you start building them. (That's true) whether you are building a house or anything else."

  • Wind vs. nuclear - uneven playing field

    Trock,

    Wind powerplants are used as tax write-offs. No one can use a nuclear powerplant as a tax write-off, because there are no tax write-offs avalailable for nuclear powerplants. Additionally, those tax write-offs are artificially inflated by fraudulently-high estimations of wind powerplant generation capacity -- which instances of fraud would be more difficult to execute in the stricter regulatory environment that surrpunds nuclear powerplants.

    One of the many other exclusive subsidies that wind powerplants receive is a lifetime 2-cent/kWh (and automatically rising with inflation) generation subsidy. The subsidy-distorted economics tend to work in favor of wind powerplants, and against nuclear powerplants.

    It is also easier to execute a wind powerplant venture because the regulatory environment surrounding wind power is so much laxer than that surrounding nuclear power.


    It does not solely matter that nuclear powerplants only cost 1/8th what wind powerplants cost. There are other factors involved in the decisions that utilities and investors make.

  • Fuel energy-density in light of octane-level

    Clark Williams-Derry wrote in the original post: Ethanol isn't quite as "energy dense" as gasoline. A thousand gallons of ethanol has about the same amount of energy as only 610 gallons of gas.

    Here in the Northwest (British Columbia, Washington, Oregon, and Idaho) we use about 6 billion gallons of gasoline per year. So if the poplar research is close to being right, it would take about 9.2 million acres of poplar plantations to satisfy our gasoline appetite.

    Energy-density of fuels is irrelevant if engine-efficiency is not mentioned. Engines optimized for ethanol's higher octane-level are more-efficient than standard gasoline engines -- so much so that the energy-density differences become negligible.

    2007 kilowatt-hours of energy, assuming coal costs $1.50 per million btu's, is equal to around $10 worth of coal.


    Sunflower wrote: If solar concentrator efficiency is 80% (easy)

    Have you ever seen a heliostat with a concentrator-efficiency above 10%? Please point out a picture of one.


    Sunflower wrote: If solar concentrator efficiency is 80% (easy) then solar concentrators in Colorado are worth $748 per square meter aperture (per 11 square feet).

    You were first placing a value on the land that has potential to support solar concentrators, not on the concentrators themselves. Your conclusion is thus an equivocation. At $1 million per acre, a square meter of land is worth around $250. In relation to the energy-value of coal, and at a generously estimated concentrator-efficiency of 10%, a square meter of Colorado land -- coopted for solar-energy mining -- is worth $1 per year, or $10 amortized at a 10% discount-rate.


    To put this in perspective, a 100-acre 10-gigawatt-electric nuclear powerplant unit produces 230 billion kilowatt-hours (kWh) of thermal-energy per year, or 2.3 billion kWh per acre-year, or 570,000 kWh per square-meter-year. If your square-meter of Colorado land is worth $1 per year if coopted for 2,007 kWh per year of solar thermal energy-mining, it is worth $285 per year if coopted for 570,000 kWh per year of heavy-metal fissioning.

    The value of a typical square-meter of Earth continental surface (150 trillion square-meters) in terms of its fissionable heavy-metal content's (~150 trillion tons, so around one ton per square-meter) heat-value in terms of $1.50/million-btu's coal is around $100 million.

  • Oil prices 100 years from now

    Odograph,

    California requires a special blend of gasoline. Therefore, it is at a leverage disadvantage in price-negotiations with refineries, and further-therefore California gas prices are inherently irrelevant.

    Next year, the earth's crust will contain 40-trillion tons of uranium and perhaps quadrillions or more barrels of oil. Oil prices next year will continue to be as irrelevant as they are this year, and other than that will probably continue to be priced slightly-higher than normal because of lack of investment in oil-field development and general incompetence throughout the third world. More relevantly, oil prices 100 years from now will continue to be low enough to easily be able to fuel a worldwide fleet of billions of cars like this one.

    Gasoline is not oil. Oil has not been near its peak (some $110/barrel, in terms of monthly averages), not to mention exceeded it, in decades. The 2007 CNN article you linked states, "The price of $1.35 in 1981 works out to $3.15 in current dollars, [Trilby Lundberg, publisher of the survey] said." Perhaps Lundberg is mistaken. Tom's inflation calculator says that $1.35 in 1981 equals $3.31 in 2007.

  • Uranium may push Peak Oil far into the future

    Justlou,

    Heavy oils, tar, and shale oil are hydrogenatable via nuclear power. (This is why heavy crude is more-valuable than light crude. It has more carbon, and the carbon is what is valuable since it can act as a hydrogen-carrier. Hydrogen, and hydrogenation, thanks to nuclear-power, are available essentially free-of-charge.) All discrete resources are rechargeable, but general bound-energy is not rechargeable. The earth's crust happens to contain 40-trillion tons of uranium, which works out to billions of years worth of present-burn-rate general bound-energy -- or half a millennium of 10-trillion-fold-per-millennium (3.04% per year) civilization-energy burn-rate growth.
    google.com/search?q=uranium+crust+cowan+grl

    World petroleum extraction rates can continue increasing yearly for many decades, and probably for many centuries. There really is a lot of oil in the crust, and even $500 for a barrel of heavy crude would still work out to a gasoline cost of only $5/gallon (assuming a 42-gallon barrel of heavy-crude, tar, or shale-oil can be nuclear-hydrogenated into 100 gallons of gasoline {or other light hydrocarbon fuel such as iso-octane, ethanol, or methanol}). Again, the nuclear-hydrogenation is essentially cost-free, so the cost of gasoline simply depends upon the price you set for the oil on the land you own.

    Stalled plans to build new high-efficiency wind turbines could get a jump start thanks to a government plan to pay residents for decreased property values

    Property owner resistance over plans to replace the country's 5000 existing wind turbines with fewer high-efficiency models has the government suggesting that homeowners living in the shadow of the 150-metre giants be compensated for lost property value.

    Most politicians and citizens are in agreement that wind power is the way to a cleaner, more environmentally friendly future, but many also believe rows of wind turbines are an eyesore and destroy the harmony of the nation's gentle landscape.

    The new initiative to compensate property owners comes on the heels of a report from a special commission created by parliament to determine the most aesthetic means of erecting new wind turbines across the country.

    Although about 20 percent of Denmark's energy is generated by wind power, the amount needs to rise significantly if the country is to achieve the 2009 wind power goals set by a parliamentary agreement three years ago. Replacing existing models with a reduced number of larger ones has been proposed as a way to reach those goals.

    But citizens' groups concerned about the effects the new wind turbines have on the landscape have managed to stall the process. Connie Hedegaard, the environment minister, believes the new initiative will help get it back underway.

    `If you live near a new wind turbine, you should be able to receive compensation from the state,' she told Weekendavisen newspaper. `But note that it is only if one can document that they've suffered a financial loss from the placement - in the same way as those who live close to a new motorway.'

    Hedegaard has called together the mayors of 22 cities to discuss the issue in August and to work out the details of such a plan. The opposition, however, is pushing her to bypass the meetings and use her authority to dictate where the wind turbines should be placed, putting up as many of the new wind turbines as necessary to meet the country's targets for reducing carbon dioxide emissions.

    Hedegaard said she would rather have the debate on a local level.

    `I still think it's best to discuss the situation out in the communities,' she said.'There are cultural lines in the landscape that you can't necessarily see just by looking at a map.'

    When wind turbines began to sprout up in earnest at the beginning of the decade Uffe Ellemann-Jensen, the former leader of the prime minister's Liberal Party, expressed the feelings of many when he called wind turbines `politically correct, economically questionable and ugly'.

    Kim Mortensen, the party's energy spokesperson said, however, that it would push to raise the subsidy to DKK 0.29 per kilowatt hour.

    From the selling price of the Dewalt pack ($169) we can estimate that 1kWh of the A123 battery cost about $2400. This is competitive for powertools and e-bikes but it needs to drop to about $1200 to be competitive for use in HEVs (the current NiMh cost about $1200 /kWh but they are heavier and more space demanding than lithium). [...] For the battery price to be competitive for a mass market for PHEVs I believe that the price must hit about $600 /kWh or lower so that a 8 kWh pack would cost about $5000 per vehicle.

Do you believe that nuclear energy is subsidized to the tune of $493 billion or more per year? If not, how high do you think -- or how high would you guess -- the nuclear subsidies really are?

    Shifting to a wider scope, it has been pointed-out that nuclear energy is neither any single-one -- nor any combination -- of the world's nuclear industries. The two are separate concepts:

  • Diffuse power is human-capital inefficient

    Jon Rynn wrote in the original post: It's actually a good thing that wind turbines are complex -- they could support a vast range of manufacturing firms, the kind of firm that provides the basis for industry in general, such as machine tool makers, ball bearing makers, steel companies, etc

    That is the very problem with windpower and other diffuse energy sources: they inefficiently leverage human-capital. America's Portland-cement industry, on the other hand, is an example of one that has improved its human-capital efficiency:

    Efficiency Gains

    Employment in the U.S. cement industry has declined dramatically during the past 20 years. In 2005, the cement industry employed 16,859 workers--a 23% reduction compared to 1985 levels. This drop in employment is the result of industry efforts to increase efficiency by automating production and closing small kilns. The average kiln in use today produces nearly 70% more cement than an average kiln produced 20 years ago: 504,000 metric tons in 2004 compared with 297,000 metric tons in 1984.


    Jon Rynn later commented: NYTimes [...] they're talking about coal and nukes, like $2000 to 3000 per kwhr when wind, according to Gar Lipow, is closer to $1500.  The cost of materials (e.g., nickel) and transporting the equipment is skyrocketing.  So why doesn't "the market" stampede to wind?

    Windpower does not leverage its upfront capital costs with 70% capacity-factors (like coal) or 90% capacity-factors (like nuclear). It does not achieve less-than 2% unscheduled downtime (as nuclear does). It does not feature production-costs of under 2-cents/kWh (as nuclear does). It dies not have its upfront capital pay for a  plant that lasts 40 years (as coal does) or 60 years (as nuclear does).

    At the same time, though, it does take most of the very same recently-expensive materials to build windpower plants.


    Jon Rynn even-later commented: It has occurred to me that a tremendous advantage of solar/wind/geothermal is that the source is free -- it is essentially fuel free.

    Wind, solar and geothermal are not fuel-free. All three actively-mine their fuel. Due to their inefficient leveraging of human capital, the fuel for the former-two is more-costly than for any other major type of energy generation. The fuel for the latter-one is competitively-priced only in a few select locations, such as Iceland.

  • Nuclear-power reduces environmental radiation

    Sarah van Schagen wrote: Radiation under ground


    phyast.pitt.edu/~blc/book/chapter12.html

    When uranium is mined out of the ground to make nuclear fuel, it is no longer there as a source of radon emission. This is a point which has not been recognized until recently because the radon that percolates out of the ground originates largely within 1 meter of the surface; anything coming from much farther down will decay away before reaching the surface. Since the great majority of uranium mined comes from depths well below 1 meter, the radon emanating from it was always viewed as harmless. The fallacy of this reasoning is that it ignores erosion. As the ground erodes away at a rate of 1 meter every 22,000 years, any uranium in it will eventually approach the surface, spending its 22,000 years in the top meter, where it will presumably do great damage. The magnitude of this damage is calculated in the Chapter 12 Appendix, where it is shown that mining uranium to fuel one large nuclear power plant for one year will eventually save 420 lives! This completely overshadows all other health impacts of the nuclear industry, making it one of the greatest lifesaving enterprises of all time if one adopts a very long-term viewpoint.

    world-nuclear.org/info/inf02.html

    In assessing the cost competitiveness of nuclear energy, decommissioning and waste disposal costs are taken into account.
    [...]
    Nuclear energy is, in many places, competitive with fossil fuel for electricity generation, despite relatively high capital costs and the need to internalise all waste disposal and decommissioning costs.
    [...]
    For nuclear power plants any cost figures normally include spent fuel management, plant decommissioning and final waste disposal. These costs, while usually external for other technologies, are internal for nuclear power.

    Decommissioning costs are about 9-15% of the initial capital cost of a nuclear power plant. But when discounted, they contribute only a few percent to the investment cost and even less to the generation cost. In the USA they account for 0.1-0.2 cent/kWh, which is no more than 5% of the cost of the electricity produced.

    The back-end of the fuel cycle, including spent fuel storage or disposal in a waste repository, contributes up to another 10% to the overall costs per kWh, - less if there is direct disposal of spent fuel rather than reprocessing. The $26 billion US spent fuel program is funded by a 0.1 cent/kWh levy.

    If that 5% decommissioning cost is considered too high, the owner may choose to delay such decommissioning by placing the reactor unit into Safe Enclosure (Safestor) mode.
    world-nuclear.org/info/inf19.html

    Safe Enclosure (or Safestor): This option postpones the final removal of controls for a longer period, usually in the order of 40 to 60 years. The facility is placed into a safe storage configuration until the eventual dismantling and decontamination activities occur.
    [...]
    Safe Enclosure (or Safestor) allows significant reduction in residual radioactivity, thus reducing radiation hazard during the eventual dismantling. The expected improvements in mechanical techniques should also lead to a reduction in the hazard and also costs.
    [...]
    Experience in the USA has varied, but 14 power reactors are using the Safestor approach

    While the unit is in Safestor mode, the funds collected for its decommissioning can continue to earn interest in a deposit account.

    As a power plant operator in a conventional gas fired plant, I wanted to add a few comments. These will be disjointed some, but, points needed to be made.

    1. I've worked Geothermal. It's rare to be able to build it because there are so few sites in th world. Secondly, after tapping the steam, the steam flow tends to decrease over time, even with water injection of waste water from the turbine condenser. Thus, in Calorinia's geo-thermal plants at the Geysers, megatt output has dropped by almost half, from over 2,000 MW down to 1,000.

    1.2 Geothermal stinks. It is heavily polluted, lots of sulpher, lots of CO2 that escapes.

    1.3 It can be used for base-load and is easily dispatchible, since we are talking a conventional steam turbine (with Earth as the boiler).

    1.4 Because there are all low pressure steam supplies from the Earth, building turbines is expensive as they have to have larger, and longer turbine blades.

    1.5 Waste abatement is a pain in the butt because each unit produces tons of chemical waste.

  • Pet social-control vs. real risk-management

    JMG wrote: The key environmental advantage is that it makes driving insurance a variable cost that rewards people for taking mass transit/biking/walking

    How did you determine that that is an "environmental advantage"? If society benefits from that, why would it not use a more-direct lever? If the "environmental advantage" is reduced carbon emissions, why not tax carbon?

    When an incorrect lever -- such as pay-at-the-pump insurance for reducing driving -- is used, conflicts of interest arise. In the case of your proposed incorrect-lever, there is no incentive for drivers to drive more-carefully, and there is no incentive for insurance companies to vet their drivers more competitively. You pointed it out yourself: "companies would submit bids to handle all claims for those drivers, using the same actuarial stats the companies have now." That is exactly the problem.

    Baby steps are being taken to resolve that problem. For example, Progressive Insurance is testing an on-board telemetry system that records brake and steering input and rewards drivers for patterns associated with safer driving. Safer speeds could also be recorded. There are systems being developed to detect impaired sriving by using powerful statistical algorithms to analyze steering-wheel input (more sophisticated than the system Progressive is testing). This way impairment of all types (sleepy, kids in back seat, pets, conversation, all types of over-the-counter and prescription pharmaceuticals, alcohol, drugs no-one has ever heard of) would be charged-for (and up-front), instead of merely alcohol.

    No-one would ever get pulled over for DUI. In fact no-one would ever get pulled-over, because there would be no need for enforcement of any kind, other than insurance enforcement -- and that could be handled via radio-tag. If you drive without a valid radio-tag, you don't get more than a mile (inexpensive tag-checkers can be placed everywhere; valid-codes are sent to legitimate insurance entrepreneurs; code-scam rings are hunted and busted nationwide by the FBI -- just as all other scam-rings are hunted and busted nationwide by the FBI) before the justice system steps in to apply leverage.

    Progressive Insurance's system now also records how many miles are driven:
    portlandtribune.com/news/story.php?story_id=117641490783192300

    The program, offered by Progressive Insurance Co., allows drivers discounts of up to 25 percent off regular rates based on when and how much they drive.

    But it requires more than the honor system. It requires people to plug a small device into the steering column of their car, which then uses the car's computerized systems to monitor how, when and how much the car is being driven.

    "On average, people who drive more have more accidents than people who drive less," said Michele Strub-Heer, product manager for Progressive Direct, which is offering the insurance.

    Progressive's program, called TripSense, is "for people who drive fewer miles than the average or drive at less-risky times of the day," Strub-Heer said. "For us, we're always looking for more accurate ways to price insurance. And we can reward people who take control of their driving habits, drive less and drive less risky."

    $10-per-year car-insurance is coming -- and it will not be because of conflicted-interest pay-at-the-pump arbitrary-social-control schemes.On We can have both posted 2 years, 5 months ago 31 Responses

    The most-scalable resolution to that might be to simply require that all drivers be continuous-real-time insured, reduce all non-insurance-checking police-traffic-enforcement to zero, and deregulate/demonopolize the insurance industry. A low-risk driver might pay a total of $5 or $10 per year in insurance. A high-risk driver might pay $100,000 per year in insurance -- if he does not change his behavior. In reality, since drivers would receive real-time feedcack on their driving, virtually all drivers would reduce their risk, insurance costs to drivers in general would fall, and profits to insurance companies (since there would be less accidents to pay for) would go up.

    The few drivers who failed to respond to this real-time risk-feedback would (unless wealthy) simply not be able to afford to drive.On We can have both posted 2 years, 5 months ago 31 Responses

    In Japan, this class of vehicle is called the Kei car.
    en.wikipedia.org/wiki/Keicar

    Kei car (K-car) (keijid¨­sha), is a Japanese category of small automobiles, including passenger cars, vans and pickup trucks. They are designed to exploit local tax and insurance relaxations, and are exempted from the requirement to certify that adequate parking is available for the vehicle. These standards originated in the times following the end of the Second World War, when most Japanese could not afford a full-sized car yet had enough to buy a motorcycle. To promote the growth of the car industry, as well as to offer an alternative delivery method to small business and shop owners, Kei car standards were created.

    The cars feature yellow licence plates, earning them the name "yellow-plate cars" (black numbers on yellow background for private use and yellow numbers on black background for commercial use) in English and Spanish-speaking circles.

    Because the regulations only restrict physical size and engine power, manufacturers have introduced many advanced technologies to the class. As a result, kei cars are often available with forced induction engines, automatic and CVT transmissions, front-, rear- and four-wheel drive, hybrid drivetrains, air conditioning, GPS and many other features.

    Stirling engines that run on small temperature differentials are quite large for the amount of power that they produce, due to the heat exchangers. Increasing the temperature differential and/or pressure allows smaller Stirling engines to produce more power.

    Dissipation of waste heat is especially complicated because the coolant temperature is kept as low as possible to maximize thermal efficiency. This increases the size of the radiators, which can make packaging difficult.

  • The automobile was an environmental solution

    wiscidea wrote: might consider exchanging my car for a horse or, during nasty weather, a horse and buggy. Would that be more environmentally sound?

    The automobile was adopted as a solution to the environmental, health, and animal-abuse problems of horse-based transport.
    google.com/search?q=automobile+horse+abuse+pollution
    enviroliteracy.org/article.php/578.html

    The most severe problem was that caused by horses defecating and urinating in the streets, but dead animals and noise pollution also produced serious annoyances and even health problems. The normal city horse produced between fifteen and thirty-five pounds of manure a day and about a quart of urine, usually distributed along the course of its route or deposited in the stable. While cities made sporadic attempts to keep the streets clean, the manure was everywhere, along the roadway, heaped in piles or next to stables, or ground up by the traffic and blown about by the wind. In 1818, in an attempt to control the manure nuisance, the New York City Council required that those who gathered and hauled manure, so-called "dirt carting," to be licensed, also restricting aliens to this type of carting activity. Thousands of loads of manure were gathered on special "manure-yards" to undergo a process of "rotting," and "gangs" of men were employed to overturn the manure and to expose it to weathering. In 1866, the Citizen's Association Report on the Sanitary Condition of the City observed that, "The stench arising from these accumulations of filth is intolerable."
    [...]
    Increasingly [...] it became obvious that the most effective way to eliminate the "typhoid fly" [...] was to eliminate the horse.

    The ASPCA was created as a reaction to the urban-horse-abuse problem:

    Other issues arose. The ASPCA was founded in 1866, and almost all cities soon had humane societies with police powers, which kept a close eye on street railways. The latter, however, found ways to manipulate these groups, for example by having officials serve on their boards and getting them to lobby for municipal regulations which required cars to stop only at corners, instead of wherever flagged down. This made the horses' lives easier, since fewer stops meant less wear and tear on their legs, and also increased route speed. Street railway owners also hoped that these societies would restrain driver cruelty, since they feared that their employees would damage their stock. However, the actions of such organisations were hardly predictable.

    Gradually well kept statistics demonstrated that horses were not as safe as people had once thought; for example, per vehicle, horse transport killed more people than internal combustion engine travel would do later. (Machines do not bite or kick, or take fright at pieces of flying paper.)


    Additionally, horses walk about 4 MPH.

    Even a rudimentary and inexpensive (read: equipped with minimal batteries) converted-electric-car could travel a long way at 4 MPH (electric cars are more-efficient the slower they travel).

  • Subsidize futures-trading to increase MPG?

    David Roberts wrote: We could buy every one of them, scrap them, and replace them with plug-in hybrids

    There are no plug-in hybrids. Creating a product that satisfies a demanding and complex market is not simple.

    Americans base their car-buying decisions on a broad array of triaged factors. The fuel-economy factor is far peripheral in most car-buyers' triage geometrics. The single-most important reason for that is that liquid-fuel is available for virtually-free throughout the United States.

    A rise in the general longitudinal price of liquid-fuel would change that. One important factor in terms of liquid-fuel price is the price of oil futures. Another important factor is fuel-tax level. To strengthen the former factor, a government might reduce futures-trading taxes -- perhaps even to the point of subsidizing futures-trading. As for the potential helpfulness of the latter strategy, it might be profitable to keep in mind that futures-trading involves significant investments in terms of time (for research and analysis), costs-of-capital, and transaction-costs. The maximum benefit of futures-trading to society might be realized if these costs were minimized by the benefitting society.

    Currently, long-term capital-gains are taxed at 15%.
    en.wikipedia.org/wiki/Capital_gains_tax_in_the_United_States


    One factor that affects the perception of liquid-fuel cost is the ratio of driving's fixed-costs to liquid-fuel costs. One fixed-cost that might easily be transformed -- and overall reduced in the process -- to a variable-cost is car-insurance. I have mentioned this before. So have others:

    You wrote that here, where you discussed combined heat and power.

    1. That scheme is only efficient in terms of thermal-potential of the fuel. As the world ramps up to 10-trillion-fold its current energy-use rate, HVAC will become decreasingly relevant in terms of power demand. However, electricity -- because of its versatility -- will be king.

    2. Fuel is cheap. Human resources are expensive. Schemes to save fuel at the expense of human-resources are economically nonsensical.

    The proposed Cliffside coal-burning power plant, to be built west of Charlotte, would cost $1.8 billion for construction and about $600 million to finance. The company expects to offset the cost by a $65 million federal tax credit awarded to advanced coal-fired plant designs that limit pollution.

    Duke Energy had estimated earlier this year that building and financing one Cliffside unit would cost $1.53 billion, plus about $435 million in financing. Turner said the cost increase comes to about 17 percent when adjusted for inflation.

    $1,800 million / 800 megawatts = $2.25 million per megawatt. That would be $2,250 per kilowatt.

  • Why a paraboloidal-reflector instead of a sunshade

    GRLCowan wrote: The thermal radiator at the paraboloid's focus [...] radiates no more and no less than it would without a paraboloidal reflector around it.

    Yes.
    .

    GRLCowan wrote: What is the paraboloid doing that a simple sunshade would not?

    The paraboloidal-reflector is limiting the heating of the environment immediately around the radiator, limiting the greenhouse-effect photonic-backscatter heating of the general earth-biosphere, limiting the photonic backscatter from the general particle-cloud of the solar-system, and increasing the photonic leverage over that of the starry night. With this set-up, only a radial tiny bit of the starry-night can see our radiator, and vice-versa.

    The first major problem is getting the heat of the biosphere out of the earth's atmosphere. (A miles-tall, evacuated-and-diamond-capped reflector might help; or perhaps locating the heatpump-radiator-reflector assembly on a mountain.) After that, it is still helpful to use a tight beam in order to 1) avoid having photons absorbed or reflected-back by solar-system flotsam-and-jetsam (including planets, moons, asteroids,  rocks, dust, cosmic particle-rays, hydrogen, etc.), and 2) increase lever-advantage over that of the galactic or cosmic background.

    I suspect that shading from the sun (the source of a mere 1,000 W/m2 of photonic-pressure) would be irrelevant to the photonic-pressure produced by our 3,000 degree-kelvin radiator. Or perhaps when you said "sunshade" you meant to refer-to our radiator as a little synthetic-sun that the surrounding environment would need to be shaded from (in order to achieve the goal of pressure-diversity).
    .

    In a nutshell, we want 1) to maximize photonic-pressure diversity in the earth's biosphere, and 2) our pressure-outlet to see as little back-pressure and backsplash as possible.

If you do not agree, simply ask yourself when you have ever seen a motorcyclist wearing a bicycle helmet -- even when and where it was legal to ride with no helmet and many motorcyclists were helmeted.

    One advantage of electric bicycles (and in reality they are actually motorcycles) is that they give bicyclists more freedom to choose effective body-armor.

    Acceleration is indeed a danger factor in terms of its putting a body or vehicle in a space-time-velocity that other operators are less likely to anticipate -- and is in this respect identical to speeding. If a car-driver wanting to enter a roadway via a left-hand turn looks left and sees no traffic, then looks right and sees no traffic, and then pulls out into the roadway only to be T-boned on the left by a vehicle, it matters not whether the principle factor weighting the failure-to-anticipate was the T-boning vehicle's acceleration or whether it was on-the-other-hand its speed -- the result remains the same.

    Thank you for pointing that out. I know that I already answered your comment, but I recently had some new insights that I would like to add to this old thread:

    Heat radiant-flux of a given body, at a given mean thermal-pressure, is lowest when that thermal-pressure is distributed evenly. Making the thermal-pressure distribution uneven, even in the slightest amount, raises radiant flux. To make thermal-pressure very very uneven, it is helpful to employ heat pumps and parabolic* reflectors (aimed at the 20-30 Kelvin starry background). Discussion on the latter can be found here:
    halfbakery.com/idea/Cosmic_20Background_20Refrigeration?op=aye

    The fact that each reflective-parabola is also a rocket nozzle, that -- even when merely employed as a heat-dumper -- accelerates the body it happens to be attached-to, is another issue.

    2008 through 2049 inclusive would be 42 years. The result of compounding 5% reductions per year would be .95 to the 42nd power = 0.11598. The emissions-reduction would therefore be 88.4%. If we include the year 2050, for a total of 43 whole years of reduction, the result would be .95 to the 43rd power = 0.11018, or an emissions-reduction of 89.0%.

    By the way, why are we planning on reducing emissions when they might prove to deliver healthy stress, and when carbon might prove to be easy to filter from the atmosphere?

    Peak Moment 63: Hot topics from Richard Heinberg: record-high U.S. fuel prices; the ethanol big-business boondoggle; coal projected to peak about a hundred years early (around 2020); what the climate change discussion is missing; and enjoying ourselves as we "go local." [www.richardheinberg.com]

    At 14:49 in that video, Richard Heinberg says, "Uranium supplies [are] also going to peak well-before 2050, even in the best-case scenario."

    How long, GreyFlcn, do you figure it would take for human society -- at its present power-consumption level -- to burn through 1% of the ~40 trillion tons of uranium in the crust?

  • Nuke production-costs (O&M + fuel): 1.66c/kWh

  • Flow my tiers, the energy-man said

    An energy-internet either will never be needed or will not exist for very long. This is because the high prices envisaged for vehicle-stored energy could not exist as prices would immediately flatline (this is true in any highly-fluid market trading a non-degradable commodity).

    It also should seem odd to "energy internet" predictors that the real internet uses no such pricing market. If the real internet worked that way, real-time prices would go up as interent-traffic went up, and vice-versa. Instead, we pay a flat subscription fees every month, with higher-bandwidth service-subscriptions costing more, and higher-reliability service-subscriptions similarly costing more. In fact, if power-service were priced that same way internet service is priced, only in a more-sophisticated way that involves Reliability- and Bandwidth- Tiers, it would look a lot like this Gristmill-comment decribes:

  • Denmark's electricity is pricy due to windpower

    GreyFlcn wrote: Denmark just pays more for electricity

    No, it does not.

    Denmark pays more for retail electricity (and much of its electricity is imported, in order to subsidize the wholesale costs of its domestically-produced windpower). Denmark's wholesale costs for domestically-produced electricity (55% from coal, 21% from gas and 12% from wind) are comparable to those in other nations.

    world-nuclear.org/info/inf99.html

    Denmark has had a wide range of incentives for renewables and particularly wind energy, accounting for nearly one third of total wholesale electricity prices. Apart from the Purchase Obligation (PO) for renewables providing an effective subsidy, there is a further economic cost borne by power utilities and customers. When there is a drop in wind, back-up power is bought from the Nordic power pool at the going rate. Similarly, any surplus electricity is sold to the pool, though is deemed to be non-PO power. The net effect of this has been growing losses as wind capacity expanded. Official estimates put the expected losses at DKr 1.5 billion per year.

    world-nuclear.org/info/inf17.html

    Increased nuclear capacity in some countries is resulting from the uprating of existing plants. This is a highly cost-effective way of bringing on new capacity.

    Numerous power reactors in USA, Belgium, Sweden and Germany, for example, have had their generating capacity increased. In Switzerland, the capacity of its five reactors has been increased by 12.3%. In the USA, the Nuclear Regulatory Commission has approved 110 uprates totalling 4700 MWe since 1977, a few of them "extended uprates" of up to 20%.

    Solar power plant explodes

    DAGGETT, Calif., Feb. 26 (UPI) San Bernardino County authorities say a tank of chemicals at a solar power plant in Daggett, Calif., has exploded, spawning a fire that may burn throughout the night. Fire Department spokesman David McLees says all the employees at the SEGS2 plant were accounted for shortly after the explosion rocked the plant at about 6:05 p.m. today. McLees says the fire is being fueled by a 700,000-gallon tank of Therminol, a fluid used in heat transfer because it can be heated to 850 degrees. The fluid is heated on solar panels, where it reaches maximum temperature, then runs through pipes in a heat transfer area, where it turns water into steam. The steam powers turbines that create electricity. Sheriff's deputies say a 1/2-mile area along Interstate 40 near Barstow is being evacuated because of Therminol's slightly toxicity. McLees says firefighters have no estimated time of containment for the fire.

    The Carnot efficiency-limit is calculated by taking the solar color-temperature (6,000 K) and dividing the ambient-temperature-difference into it. In this case, an ambient temperature of 312 K (39 C) was assumed. (6,000 - 5,688) / 6,000 = a 94.8% efficiency limit.

If you pay for all of that in advance, and you get lucky, it is free -- in the same way that buying a lifetime-supply of cars, car-maintenance, car-repairs, and gasoline in advance, and getting lucky, would make driving free.

    Have you ever wondered, Sunflower, why remote land in Alaska is so cheap, when land sells for $1 million/acre on the California coast? Is it because passive solar energy is free?

  • A 100%-nuclear grid is 100% dispatchable

    Gar Lipow wrote: if we are talking about a low or zero carbon grid, you will still need actual dispatchable electricity -- which will require either electricity storage, or storage of high temp heat. (Note that this even applies to nukes. [...] storing some of their output [...] you can [run them] at close to full capacity most of the time.
    (Emphasis added by Nucbuddy.)

    Including your qualifier require, your statement does not apply to nukes. You can profitably run them at full capacity all of the time, as long as the competition is more expensive. (Yes, that is a tautology, but your statement -- being fallacious --  happens to reduce to an absurdity.) At $0.03/kWh, it only costs $0.72 to produce a full 24-hour day of a nuclear kilowatt. All you have to do to break even is make that $0.72 in a day, and it doesn't matter how you do it -- even if, at night, you have to sell your kilowatt for $0.01/kWh, or even route your kilowatt to a shunt (e.g., a powersink) for $0.00/kWh.

    If our nuclear kilowatt were to sell for an average of $0.01/hour between 8PM and 8AM (12 hours = $0.12), $0.03/hour between 8AM and 12PM, and 6PM and 8PM (6 hours = $0.18), and $0.07/hour between 12PM and 6PM (6 hours = $0.42), we would meet our break-even point. We could even shut-down overnight, if the noon-to-six slot were $0.09/hour. However, it is important to note that electric power, like any other commodity and no-matter how abundant it is, is never really worth zero. To take advantage of that fact, metering might be done-away with (as, in fact, it has been done-away with in relation to other utilities such as local telephone service and internet service) and replaced with tiered service (similarly, as metering in-fact has been replaced -- though crudely, and not in the elegant way described below -- with tiered-service in relation to telephone and internet).


    Tiered-service would work like this: multiple (say, for example, five) service-Tiers would be made available. The Tiers would represent reliability-factors, and the more-expensive the service-Tier, the more-reliable the service. At any given instant when demand exceeded capacity (e.g., whenever there were no power-service to be routed to a shunt), Tier-1 service would be the first to go and tier-five service would be the last to go. The service-cutoff progression would look like this, numbered in-order from low demand/supply conditions to high demand/supply conditions:

    1. Tier-1 rolling blackout. All higher Tiers good.
    2. Tier-1 total blackout. Tier-2 rolling blackout. All higher Tiers good.
    3. Tiers 1-2 total blackout. Tier-3 rolling blackout. All higher Tiers good.
    4. Tiers 1-3 total blackout. Tier-4 rolling blackout. Tier-5 good.
    5. Tiers 1-4 total blackout. Tier-5 rolling blackout.
    6. Tiers 1-5 total blackout. No power available to anyone.

    (Note that Condition-6 would only occur when no powerplants were online, or when the transmission system had suffered a total failure to route to at least one Tier-5 subscriber. Demand alone would not be capable of producing an instance of Condition-6. It could only occur at an instant when supply were at exactly zero.)

    Your guarantee of reliability at your given Tier is the fact that there exists some given proportion of service-subscribers below you. Tier-1 subscribers, of course, have no such guarantee and can probably bank on at-least daily rolling blackouts.

    The free-market would set prices. If you were dissatisfied with your Tier, you could move up to a more-expensive Tier. If you were on a budget or could somehow economically store your power, you could move down and live with sometimes-power.

    However-much power you might draw at any given instant, as long as your service were not blacked-out, wou
