New Source of Biodiesel

Grist is reporting about a bout trying to set the round the world speed record.

Here's a nice PR gimmick (and by nice, I mean totally disgusting): power your monster "eco-boat" with biodiesel made from human fat:

You can also make biodiesel from tallow (animal fats), fish oil, seaweed and algae. In fact, in an extraordinary show of dedication to the project, the skipper, Pete Bethune, underwent liposuction, and the fat (all 100ml) was used to make a small amount of Biodiesel for Earthrace!
