Tomorrow, May 15, is Bike To Work Day in the San Francisco Bay Area. A persistent rumor claims that riding a bike is actually less efficient than driving a car if you account for the energy that goes into producing the food/drink that "fuels" a cyclist.

The ethanol "alternative"? Well, not really. Instead of burning ethanol in engines, from a transportation standpoint we're far better off ingesting the stuff. Driving 48 miles takes more than two gallons of ethanol, whereas only eight ounces of liquor, a mere half-pint of vodka, can fuel a cyclist for the same distance. Happy trails!
