New Zealand skipper Pete Bethune and his wife have mortgaged their house to finance a trip around the world. They’ll try to set a record by doing the trip really fast. The normalcy of this story stops there.

Their ship, which runs on biodiesel, will also be powered in part by human fat. It’s all a stunt to showcase alternative energy.

From the Daily Mail: “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.”

Meanwhile, the U.S. Air Force pulled a green stunt of its own this week, marking the 104th anniversary of powered flight by completing the first transcontinental flight of an aircraft using a blend of regular aviation and synthetic fuel. Those wild and crazy military types!
