Re: Don't be
"With the new quick charge lithium batteries electric cars charged by solar power and the other renewable electric power sources are THE future of transportation."
Coincidentally, I tried to research batteries last night. Someone had told me the batteries in a Prius were toxic to the environment, moreso than the enviro gains we got from using Priuses. I don't agree with that tradeoff analysis, but I did learn that the newer batteries aren't quite so clean and recoverable as we'd wish them to be.
Apparently reclamation on the litium ion battery (which Toyota is moving toward on future models so that they can get 100+mpg ) is "in its infancy" - they are merely able to recover a few metals, and that is under extreme heat. The article didn't say how that heat was generated, but I think we can all guess pretty easily.
Lithium ion is potentially explosive, and so it needs to be maintained within a fairly narrow band of temperature range. That would seem to limit its applications. Additionally, a lot of lithium ion batteries fail within the first 2-3 years, they don't make it out to the full lifetime as reliably. Thus it sounds like there is quite a waste stream. one of many sources My point being, lithium ion sounds really great, but there seem to be some hidden nightmares.
I really think "the future of transportation" is going to be as in the original quote from Umbra: "We need to design our cities and suburbs with fewer cars as a guiding principle. We need to welcome greater density in our housing. We need to fund mass transit more than we fund highways." Together with society-wide reevaluations of our perceived need for transportation and our belligerently-asserted right thereto.

Sunflower wrote about solar, and quoted solar in terms of units on the desert. The desert is a valuable ecosystem to the planet, also. Just because humans find it rather uncomfortable there, doesn't make it worthless in terms of natural capital (def: Paul Hawken, E.M.Schumacker).
Take a close look at any photo of a desert solar plant - the roads for access and maintenance, the disturbance to wildlife, plants and soils from suddenly becoming traveled and shaded.
Know that there are other places to put solar collectors, for instance every rooftop in every town and city we have. Then the power sources are right were we need them, local, decentralized. No, the power companies won't like this, because it "pulls the plug" on their Empire: the massive interstate trunklines, the grid.
In addition to the semi-rigid panels which one usually sees, there are other collectors coming into the market. Flexible solar panels are now available to be laid like roofing shingles on existing warehouses. Sheer solar collectors are now available which can surface our existing skyscrapers. Panels are now quite efficient, and can generate power at any latitude. So, don't fall for the propaganda, we don't need to mutilate our desert ecosystems to go solar.
Sunflower also presented solar within the context of a discussion on transportation fuels. I think solar is a great option for our geographically-fixed power needs (buildings, etc) but I'm skeptical it would do much for us for transportation. I did see a Solar Prius on Earth Day in Santa Barbara, but the website stats on that make it sound pretty limited. So, I repeat what I said in my last post: We must design ways to make it possible, practical, fun and cool to stop driving. On Umbra on ethanol posted 3 years, 6 months ago 28 Responses
biofuel bunk
Corn, soy, it doesn't matter, all of it is merely a transition-era bandaid. Wide-scale adoption is not possible. It is firstly a land-use issue. We do not have the planetary surface to grow biofuels in sufficient quantity to replace our appetite for oil.
When it comes to "crop waste," which is often what politicians tell us the fuel is extracted from, our soils need that biomass, not our car engines. Ref: books of Bill Mollison, John Jeavons, Howard Yana-Shapiro, et all.
Neither corn nor soy are farmed using sustainable agricultural techniques. Both crops are notorious in the GMO realm, both crops are monocropped, soil depletion issues, water issues in an age of climate change, I could go on, but read Yana-Shapiro's book if you're interested. Switchgrass has recently been proposed - another monocrop, still has the land-use issues and many of the agricultural issues listed above.
In addition to the land-use issue, there is the distillation issue. Many of these biofuels and blends are extracted using fossil fuels to do the extraction process (the politicians leave that little detail out), some with a 1:1 ratio (one unit of fossil needed to extract one unit of biofuel).
Biofuels of all sorts are being touted as the new "great thing" which will solve our problems, but they really are just a temporary and niche solution. Yes, they may ease our societal pain as we transition, but the original letter by Heidi Werner gives the only sustainable solution: We must design ways to make it possible, practical, fun and cool to stop driving.

It sounds wonderful that Wal-Mart has "goals" to cap their greenhouse emissions. That's a lot of Wal-Mart trucks, store locations, offices and supply chains to bring under ghg limitations, and would be a terrific thing. I look forward to seeing CERES level reporting which declares that they have put action behind those goals and have achieved them.
I read about Wal-Mart's recent interest in carrying organic foods and more-sustainably-produced seafood. At first it sounded terrific - wow, so much more access to these products. And the thought of such massive supply lines - agriculture, manufacturing, etc. - converted to more sustainable production - wow again. But then I stopped to think about what has been the Wal-Mart M.O. since the beginning: ultra-low prices, at any cost. It's the "at any cost" part that they never say, and which hurts us all when they act upon it.
Wal-Mart comes into town and wipes out all the mom-and-pop businesses by undercutting prices. They are then the only remaining jobs in town, at next-to-nothing wages with no benefits. (refer to Ask Umbra ) Think about who produces, supplies and sells organics at this point. Local healthy-food stores, family farms, small businesses. These are therefore destined to be the next victims of the Wal-Mart megalith.
The fledgling suppliers do not yet have enough organics to supply Wal-Mart supply chains. A 4/9/06 Los Angeles Times article tells how organic product manufacturers are currently hard-pressed to find sufficient organic ingredients to continue to call the products organic. "The producers will just make more," you say. Sounds nice, but reality is, you can't do it tomorrow out of thin air. That same Los Angeles Times article reminds us that it takes about 3 years for a U.S. farm to certify as organic - the toxins have to transition out of the soils. A 4/3/06 article at the Christian Science Monitor says that fisheries have been sustainably certified at small volume, but the industry has not yet solved Wal-Mart caliber supply. We just don't have the supply yet.
"If Wal-Mart started using or selling those items all of a sudden," Lee Scott says. Wal-Mart will enter the organics markets with massive contracts, pull all the supply, and undercut the prices at any cost. The smaller producers and retailers of organic products will be unable to compete. Once again, the megalithic corporation will crush family businesses, entrepreneurs, local economies.
And a megalithic entry into such budding industries with limited supply sounds to me like a precursor to legislation degrading the definition of organic so that more products will qualify for the then-meaningless badge of "organic."
Yes, a Wal-Mart entry into the field may stimulate more growers to turn organic, but on the other hand, at Wal-Mart discounts, is that where we really want to head? Organics farmers and organics-producers reduced to sweatshop wages. "What happens to the solar-panel market if Wal-Mart makes a large commitment to solar panels?" Scott poses. Affordability, he claims, but how do they attain that affordability? At the rape of small businesses. That part Scott won't mention.
Rather than cheering the entry of the megalith into yet one more arena for takeover, someone should hand Lee Scott a copy of E.M. Schumacker's classic Small is Beautiful. If Scott wishes to make a better world for his granddaughter, he'll work to negate that unsaid phrase "at any cost." Rather than green-washing and public relations with continued annihilation, he'll truly nurture human capital, truly steward natural capital. I hope he does it, and doesn't just pretend he will.On An interview with Wal-Mart CEO H. Lee Scott posted 3 years, 7 months ago 22 Responses
