Personally, I agree with you Reaper1. Ethanol may be a stepping block for something better, but it takes focus away from getting the avg fuel economy mandate lowered. The government is more relaxed for car companies with that are producing E85 vehicles. Also, E85 still relies on gasoline as part of the mixture, it isn't available widespread, very few cars can use it, mileage suffers on the ones that do, etc. I know they could increase the milieage with ethanol by altering the spark adv. but they don't. My E85 minivan gets terrible gas mileage with E85 and hwy miles (16-18mg) and then it takes a few tanks of regular gas to get back to good (21-22 avg hwy) mpg again (BTW, I always wait till almost empty to fill up, so very little E85 is left in the tank). I did have one good tank of E85 that I got 22mpg on hwy, but I don't know why that one was different. Don't get me wrong, I do fill up with E85 whenever I am near a gas station that sells it. I would much rather give my money to american farmers than foriegn oil lords. Anyways, I really think developements with fermentation and even alcohol producing bacteria could be a win-win situation.
Butanol is an alcohol similiar to ethanol, but it provides nearly same amount of energy as gasoline. It can be produced using fermentation of biomass materials like corn stalks and cheese whey. It would be a much better alternative to E85 because there is NO vehicle modifications necessary. None. Also it would be possible to transport it through the gas pipelines, unlike E85. Ask yourself why the government hasn't donated any funding to the development of that fuel. It doesn't require any gasoline in the mixture. Without major funding, Butanol will never reach high volumes.

BTW: My Daytona is broke, but my 1996 Saturn with all the new fangled emissions stuff, sequential injection, and DOHC gets about 27mpg on city/hwy mix. My old Pontiac Sunbird with TBI was usually around 30-35 mpg.
