Well I for one am sick of all those telling us that there is no way "alternative" fuels could possibly make a dent in the oil we use. Moore's law tell us differently (paraphrased as-technology doubles every 18 months). Yes all the corn produced by the usa may be needed with current methods; but add all the other wasted fuels- forest burns, used oils, newer techniques, more efficient engines and a corner could be turned. Biofuels is the worst answer for our energy needs... except for all the other answers.
