The fastest eco-boat on the planet will attempt to break the round the world speed record using fuel made from human fat.
Pete Bethune, the New Zealand skipper of Earthrace, said the attempt to circumnavigate the globe would begin from Valencia in Spain on March 1 next year.
Bethune and his wife mortgaged their house and sold everything they own to help make the project happen while continuing to seek support from sponsors.
Demonstrating further commitment to the cause, Bethune underwent liposuction and donated enough to produce 100ml of biofuel, while two other, larger volunteers also had the procedure, making a total of 10 litres of human fat.
This, in turn, produced seven litres of biofuel, which could help the boat travel about 15km.
Earthrace is fuelled on 100 per cent biodiesel and has a net zero carbon footprint.
The announcement was made at the QE2 pier in Greenwich where Earthrace is being hosted by Greenwich Council until January 1.
Circumnavigating the globe represents the pinnacle of powerboat challenges, and more than 24,000 nautical miles is the world’s longest speed challenge.
