Quote: On Bicycle

I always knew the bicycle was the most energy efficient vehicle but this is just amazing...
Pound for pound, a person on a bicycle expends less energy than any creature or machine covering the same distance. A human walking spends about three times as much energy per pound; even a salmon swimming spends about twice as much.
From the book Stuff: The Secret Lives of Everyday Things

Update 28 Aug: Excellent post on "How to Ride Your Bike to Work".
