    Over at Boing Boing I found an article that discusses ethanol fuel cells.

    ... Ethanol is abundant and cheap to make, relying on the well-established corn industry for its production. It is also far less volatile than hydrogen, which has seen a great deal of interest as a potential alternative fuel for automobiles.

    This could be a very nice alternative to the more popular methanol fuel cells.

    Minteer and her colleagues are focusing on small-scale applications, with the preliminary fuel cells being no bigger than five square centimeters about the size of a postage stamp. "We've tested probably 30 to 50 of the ethanol cells," Minteer says. They have successfully run their cells with vodka, gin, white wine and flat beer ("The fuel cell didn't like the carbonation," Minteer says).
