Dean Kamen, famed inventor of the Segway vehicle, drank his own urine to the delight of a South Carolina audience. He was participating in a presentation of his latest gadget- a pee-purifying device that his company DEKA Research has developed.

He intends to solve the world's water problem with this new invention-- an energy efficient filtration system that can transform any water and convert it into drinkable H20. The device, still in prototype form, is 'the size of a dorm-room fridge'.

Kamen owns one hundred and fifty patents and owns an island in the Long Island Sound. Bono is apparently interested in supporting this project and is being tapped for his high profile.
