Bad Water + Cow dung = Drinkable water and Energy!

I remember being told about Dean Kamen a long time ago by my dad. Let's just call it a superhero story. The man invented an insulin pump in the world of insulin shots; went on to design a portable dialysis machine - the thing that cleans your blood of the stuff that you should be peeing out. Before he made that, people with problems urinating or kidney problems would have to go to the hospital every once and a while to get hooked up to a big machine that cleans their blood. At the time he said that he wanted to invent something that was revolutionary, like penicillin. Ok, so he invented the Segway, and the iBOT (the amazing wheelchair that climbs stairs itself), but now he's done it.

He's been talking for a while about solving the water problems in the world, and here's his answer. The Slingshot is a 1 or 2 thousand dollar machine that distills (= no filter!) any water-containing liquid into drinkable water using the heat from burned cow poop. Gotta hand it to the guy. The Slingshot is even coupled with a generator that can power 70 energy efficient lightbulbs. I wonder if a refrigerator can be run on that.

I could only imagine that world-wide foundations are going to jump on this like nobody's business.

Ok, maybe I'm the only person who would think of Dean Kamen as a superhero.
