Peter Bethume is attempting his second circumnavigation of the planet in Earthrace, a boat that is powered by biodiesel fuel as an alternate to fossil fuel. In order to draw attention to the trip, he and two other crew members received liposuction and collected about 2.5 gallons of fat from their bodies. That’s enough to go nine miles. In all, the ship carries 3,000 gallons of fuel and can go up to 2,800 miles on a full tank. It can withstand heavy winds and 50 ft. waves. The trip has been estimated to take about 65 days.

Costing almost $5 million to create, Bethume cooked up this video last year in an attempt to raise funds for the voyage. We bet that he would still be willing to take donations, either in funding or your own body fuel.
