An interesting alternative fuel design that is "out there" now. I have some doubts about some of the biodiesel stuff from an economic and environmental viewpoint (should we be burning food for fuel???), but depending on how it's made, it might be ok. Regardless of that, it certainly works.

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.

Read the rest here... (including a video). You can also check out the Earthrace site for info. We first covered this boat with a link to this National Geographic spread back in December.
