If you listen to inventor Dean Kamen, the biggest health problem facing the world today is not AIDS, obesity or malnutrition. It's a shortage of water
Over that time it has turned dirty river water, ocean water and even raw sewage into pure drinking water. Kamen says it can turn anything that looks wet, or has water in it, into the "stuff of life."
The magic behind the Slingshot is a "vapor compression distiller" that stands between what looks like two empty fish tanks connected by a couple of hoses. One tank contains the contaminated liquid, the other is for the newly clean water.
The Slingshot boils, distills and vaporizes the polluted source, in turn delivering nothing but clean water to the other side. And it does it all on less electricity than it takes to run a hair dryer.
He says one Slingshot machine can supply about 250 gallons of water a day, which is enough for 100 people
