    Distillers grains are a high fat high protein (as the carbohydrates have been removed for fermentation) Generally the grains are of significantly higher value per mass (i believe) than corn both economically and nutritionally due to the high fat/protein contentOn The pet-food industry takes a serious look at distillers grains posted 1 year, 1 month ago 3 Responses

  • On Polotics and Reason

    People tend the view the yucca mountain project in on of two ways

    1)As a way to argue their view for or against nuclear energy

    This project is not a green light for building lots more nuclear power plants.

    Yucca mountain is is about what do with the stockpiles of nuclear waste we have scattered about the country today

    2)The not in my backyard position
    The proximity of nuclear waste to people would be greatly reduced when moved to yucca mountain and away from power plants that are in rural areas in some cases.

    The nuclear waste we have created is never going to "go-away" yucca mountain is the most safe realistic solution the problem.

  • Some quick Points

    1)The train load problem is very real and there is a solution ~ You build smaller localized plants that are co-generation (meaning the waste steam from power/refining goes to steam tunnels for heating near by buildings) This is being done in Europe

    2)I think alot of confusion comes from the term cellulosic ethanol I see people crunching numbers for paralysis (which is a waste removal technology that generates fuel as a bi-product)

    This should not be confused with more efficient enzymatic digestion methods which are in various stages of research

  • The numbers on plastics mean..

    I had a food process engineering explain to class that that basically the lower the number the more cancerous the plastic container is.

    Lower numbers mean it degrades faster and oxidizes quicker so if you have a already opened bottle of liquid you're ingesting once the bottle is opened the inside wall of the bottle begins to oxidize and degrade turning the liquid into a carcinogenic..

  • Ethanol Efficiency

    Nice Debate

    People keep saying that ethanol is about 85% as gasoline. That is true in a gasoline engine but if you stick gasoline in an ethanol engine the numbers are reversed. It has to do with the expansion characteristics of the gas.

    There was a study that got buried in the bureaucracy  about a car that runes on a mixture of ethanol and water(~30%), the normally wasted resistance heat from the combustion process vaporises the water generating more expansion pressure. You can't do this gas because it isn't miscible with water.

    In other words you can't compare ethanol efficacy to gas energy without considering gasoline in an ethanol engine would be a fraction of that efficiency.

    Not to mention this study(http://www.psfc.mit.edu/library1/catalog/reports/2000/06j ...)
    showing a ethanol turbo injection system in which
    The consumer cost payback time shows a 4:1 improvement over turbo-diesel and a 5:1 improvement over hybrid. In addition, the problems of water absorption into pre-mixed gasoline (causing phase separation), supply issues of multiple mix ratios and cold-weather starting are avoided.

    You can't compare ethanol prices to gas  
    prices without considering peak oil meaning 5-10 years from the comparison will quite different.

    Ethanol makes good sense from an economic standpoint.

    I'm glad you reduced you're usage by 80% you're really walking the walk. I'd be great if the American meat consumed dropped by 50%(thus saving the rainforest's from beef farms) too but a-lot of consumption habits are based on economic ability not conscious decisions. Look at china for example.

    Much like the nuclear power debate we have people on one side dreaming of an ideal world and others more worried about the best option for  tomorrow, the optimists and the pessimists I suppose.

    Sure reducing how much energy we use is important but we have to start bringing in more too.
