clipped from: blog.wired.com There has been much buzz about the water-purifying machine that Segway inventor Dean Kamen demonstrated on the Colbert Report last week (even taking on the bag of Spicy Sweet Chili Doritos that Colbert added). Everyone has been trying to find out more about his claim that "you stick a hose into anything that looks wet ... and it comes out ... as perfect distilled clean water."
So far as I can tell however, it's true. (Note: I still haven't worked out if it can handle volatile organics like gasoline and benzene.)
