What better way to circumvent the world than with a fat-powered boat? Peter Bethune created “Earthrace”, an eco-boat powered by biodiesel made of fat from his backside — vegetable oils and other animal fats will also be used during the 24,000-mile trip. This carbon/Kevlar-hulled speedboat sports two, 350kW Cummins engines that generate 1080hp. Video after the break. Click here for first picture in gallery.
