Slingshot Of Mass Destruction aka Slingshot Of Awesomeness

I'm not particularly a fan of weaponry, however I am a fan of DIY genious and I think that this fits into that category.

Segway Inventor Wants To Cleanup The Worlds Drinking Water

Dean Kamen the inventor most famous for bringing us the Segway has created a new device called the Slingshot which turns contaminated water into pure drinking water. The device is smaller and more energy efficient than other purifiers and can produce about 200 gallons per day. Kamen hopes to find funding partners and distributors to help keep the cost of distribution down and see his device in wide use. "In your lifetime, my lifetime, we will see water be a really scarce, valuable commodity," Kamen says.
