What it does is simple. A few years ago, Kamen was working on an electric generator for use in underdeveloped villages when he noticed that it produced about 1,000 watts of waste heat. Kamen decided to try to use that heat to make clean water. There are 6,000 deaths from contaminated water every day, according to the U.N., and safe water is one of the world's more urgent problems. Kamen's device uses that extra heat to distill waterâ€"boil it and condense it.
Nothing new about thatâ€" Kamen has invented lots of things, but he didn't invent distillation. The trick is to do it using as little energy as possible. However, 1,000 watts of heat won't boil much water, so Kamen developed a closed system, powered by whatever fuel is at hand, that traps the energy released when the boiled water vapor recondenses. Essentially, he's recycling heat. Result: a low-power, low-maintenance device that will cost around $1,000 to manufacture and makes 10 gal. of drinkable water an hour.
