More on ethanol as an automobile fuel (updated)

Matthew Wald wrote a great article on the potential of ethanol as a gasoline replacement. "Is Ethanol for the Long Haul" is published in the January 2007 issue of Scientific American . His conclusion: as long as it's made from corn, no.

He also noted the absurdity of Congress' passing laws subsidizing domestic production of ethanol from corn and preventing the importation of ethanol made from Brazilian sugar cane, ultimately resulting in higher fuel prices for Americans.
