For over 15 years, Dean Kamen (inventor of the Segue) has relentlessly pursued an effective way to clean up the world’s water supply. Fifty percent of all human illness is the result of water borne pathogens. Kamen has invented a small, energy efficient vapor compression distiller that can turn any unfit source of water (river sludge, seawater, poisoned well water, or even a "50 gallon tank of urine", as Stephen Colbert put it) into potable, safe water without any need for chemical additives or filters. Kamen has nicknamed his device the SlingShot, as in the David and Goliath story – a tiny technological solution that can take down a giant problem. But despite the brilliance of his invention, getting these machines into villages around the world has been a long and frustrating journey.
