Alright, I've officially heard of every off-the-wall fuel source possible...until tomorrow, anyway. Boats powered by alternative fuels is nothing new...human-powered (duh), wind (double duh), electricity, steam, biodiesel, solar...all fairly old hat with improvements occurring daily. But this one takes the cake.
The Earthrace is a high-tech speedcraft on its way to breaking the round-the-world speed record. Hell-bent on creating a net-zero carbon footprint to prove that earth-friendly high-power boats are possible, the 24 meter boat is lubricated with vegetable oils, the bedding foams are made from canola oils, and the crew sups on organic and local foods as they race around the world, trying to beat the 75 day record set 10 years ago by the British boat Cable and Wireless Adventurer. And the Earthrace is run, in part, on human fat.
