Eco-Superboat Powered By Skipper's Fat

Was it strange reading that title? Because it was pretty weird writing it.

New Zealander Pete Bethune's eco-boat, Earthrace, runs on biofuel made from human fat. The boat has zero carbon footprint. He's going to try to take Earthrace around the globe, hopefully breaking the record for fastest circumnavigation. He and two other volunteers got liposuction to help the effort, producing 10 liters of fat, which will take them the first 15km.

Earthrace kind of reminds us of this other futuristic eco-vehicle.
