quote: Food prices can be more accurately associated with the price of oil per barrel and gas prices increase.
quote: The corn grown to produce the ethanol used in flex fuel vehicles and the like exist for that sole purpose, while the farms growing food-grade corn are not related.
quote: Federal mandated guidelines for rates of adoption of ethanol pumps by gas stations is essential to the adoption of the technology, Lutz feels. Larger stations should be required to have 1 or 2 ethanol pumps he feels. This would eliminate the "chicken and egg" scenario he discussed where producers wouldn't produce since there was no place to sell, and oil companies refused to deploy pumps because no one was producing.Lutz expressed frustrations about the oil companies efforts to stab ethanol in the back particularly during the formation of the new CAFE legislation. He points that oil companies successfully lobbied to remove pro-ethanol language from the bill and to scrap portions of the bill that would have rolled back oil tax cuts to help fund alternative energy development by firms such as Coskata. Change, Lutz believes must start with the auto industry, but it also must happen on the national level.
quote: Combustion is not an efficient method of autolocomotion. It's just not, nothing against ethanol, gasoline, diesel or hampster-fuel; it's not the best way of moving people.
quote: (loss due to transmission for instance - isn't it something like 87%-95% efficient?)
quote: The closest competitor, electricity, has significant issues - transmission line losses are significant over long distances (even at extremely high voltages and such), and as well transmission lines are politically very unpopular
quote: They are prime NIMBY targets, as are most power plants,
quote: you need batteries of some sort to store the energy
quote: The point isn't that ethanol as a fuel is bad/worse than gasoline;
quote: we're never going to "solve the energy problem" with waste biomass. It can certainly help reduce the growth in demand somewhat for petroleum, but it's not going to do more than that.
quote: Compared to the amount of energy the average person consumes in fuel, the amount to be gained from human waste is trivial. The human body is fairly efficient at extracting energy from biomass...and we stuff far more energy in our cars than our mouths in any case.
quote: plus the cost of subsidies
quote: Since there are >2.6 gal of ethanol produced per bu of corn I wouldn't mind splitting up the extra "$2.21/gal," over $6 a bu. you seem to be suggesting ethanol production adds to the value of a bushel (56#'s) of corn. Oh wait, even with corn prices at all time highs it's not worth much more that $4/bu at the farm gate, and 100% Ethanol is worth less than $2.21 a gal on the open market.

quote: The OP was correct. While this is a major innovation, we're never going to "solve the energy problem" with waste biomass. It can certainly help reduce the growth in demand somewhat for petroleum, but it's not going to do more than that.
quote: I'm not sure where you got this information, but it couldn't be more wrong. The "energy to create" gasoline is a tiny fraction of what is currently required to produce ethanol.
quote: This design is entirely plausible with currently available technology, but requires more study before it can be declared both practical and economical.
