Proving that you can have your cake and eat it too, Peter Bethune is circumnavigating the globe with a speedboat he will power partly with fat taken from his own fat ass (literally). Powered by a biodiesel motor putting out 1080 horsepower, this 78-foot speedboat is designed with a sharp bow that actually cuts through waves rather than riding over them. Capable of 45 knots (58 MPH for us land lubbers), Peter hopes his boat will take him on the 27,600-mile journey in only 65 days, which is 10 days faster than the current speedboat record. Oh, and it looks like sex on water for good measure. Iâ€™m gonna make a run to McDonalds now, hopefully I can be the first to circumnavigate the globe in a plane powered by ass-juice.
