The Earthrace boat isn't some Greenpeace sponsored, treehugging tug. No! It's a treehugging, carbon/Kevlar-hulled, 1080-Horsepower, 78 foot speedboat with a sharp bow meant to harpoon waves. Apparently, submarining through the crests of waves is a lot more efficient than going up and over them. And, as Wired reported, the boat ran a section of its circumnavigation off biofuel processed from the captain's ass fat. Really.
