...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...

...cell generator provides a kilowatt of continuous power for eight hours on a single tank of environmentally correct hydrogen. The AirGen is a tad bulky (about the size of a mini-fridge), but you can roll it under a desk. Unlike a gas-powered generator, it emits only water vapor and heat, so it's safe for indoor use.

Hydrogen Fuel Cell For carmakers, it's the ultimate green machine: a system that runs on hydrogen and oxygen and spouts only heat and water vapor. GM says it could start mass-producing fuel-cell cars by 2010. But makers of consumer electronics may beat them to the punch. In two years NEC plans to introduce a fuel-cell-powered laptop that runs 40 hours between charges--very handy in, say, a massive blackout. Portable fuel-cell power generators sell for a mere...

...chilled to minus 260°F, which converts it to a liquid and reduces its volume. An amount that would normally fill a beach ball can fit inside a Ping-Pong ball. When the liquid arrives at terminals in the U.S., it is slowly warmed up, returned to a vapor form and sent through pipelines...
