Water from Thin Air

Dean Kamen's invention, the Slingshot, claims to be capable of producing clean drinking water from any source of moisture. The device requires no filters, operating by vapor compression distillation. This process can use anything from ocean water to urine or sewage, and extract from it pure water safe for drinking. The slingshot also generates enough electricity to power 70 energy-efficient lightbulbs. Kamen wants to distribute his product to various village entrepreneurs. Eventually he hopes to change impoverished areas around the globe by providing water for those who don't have easy access to it.
