Suck the extra fat out of your body and give it to this guy, Peter Bethune. Let him build a boat that is powered by your body fat to let you sail across the globe in super high speed! It isn't a joke, the guy mentioned here built an eco-boat, called Earthrace, powered by bio-diesel made of fat from his backside. He intends to set new world speed record for circumventing the globe in the boat next year.
