the arguement about gasoline engines still being needed to produce the ethanol is kinda invalid, ofcourse gasoline powered engines will be needed to produce it at first, no alternative engine has been offered for the tractors and power plants and such, but once it goes mainstream it should take care of itself through private enterprenuerialism (sp?).... always money to be made when something revolutionary is designed

i do however agree with the fertilizer issue, thats much more dangerous to the environment than most people realize


and as far as bio diesel goes... ah.... i can't wait...
