Pure Genius: How Dean Kamen's Invention Could Bring Clean Water To Millions

This college dropout has teamed up with the Coca-Cola company -- this is a MUST READ!

Using a process called vapor compression distillation, a single Slingshot can purify more than 250,000 liters of water per year, enough to satisfy the needs of about 300 people. And it can do so with any water source—sewage, seawater, chemical waste—no matter how dirty.

For communities that lack clean water, the benefit is obvious, but to realize that potential, the Slingshot needs to reach them first. Which is where Coke comes in: The company is not just a soft-drink peddler; it is arguably the largest, most sophisticated distribution system in the world. That’s important because the scale of the water crisis the world faces is unprecedented.

Water seems so abundant it’s easy to forget how many people don’t have a clean source of it. According to the World Health Organization, nearly a billion people lack ready access to safe drinking water, and hundreds of thousands die every year as a result. Many more fall terribly ill.

Plenty of water-purification tools exist, of course—chlorine tablets, reverse-osmosis plants—but they all have drawbacks. Either they’re not adequately portable; they require replacement parts that can be hard to come by; or, most vexing of all, they remove only certain kinds of impurities, leaving others to poison the unwitting.
