We've been on an ethanol kick for seveal years now, and overall it doesn't seem to be working out very well. Ethanol is more expensive to produce than gasoline, damages fuel systems and does not burn as efficiently as gasoline, so lowers fuel economy. I've been wondering lately why we don't try natural gas. It burns cleaner than gasoline and the conversions are relatively inexpensive. Infastructure is an issue now, but it shouldn't be too difficult to set up a couple test stations in several larger cities to determine feasability. We burn off tons of the stuff every year as a waste product in oil drilling anyhow.
