Pete Bethune, a former oil exploration engineer, is so committed to proving biodiesel is a viable alternative to fossil fuel that he and two other Earthrace crew members underwent liposuction. Together they stripped more than 2.5 gallons of fat from their bodies, which produced almost two gallons of fuel - enough to go 9 miles under optimum conditions.

One small step for two men, one giant leap for our future robot masters. We remain blazing toward the advent of robots that can kill people and generate fuel by eating their flesh.
