Clean, Safe, Cheap Drinking Water

Dean Kamen, the prolific inventor of the segway, ibot, insulin pump, etc. has developed a water purification machine driven by the relatively obscure sterling engine. The above link profiles the “slingshot” and includes a video of Kamen on the Colbert report. Hilarity ensues…. 🙂

Some great quotes from Dean Kamen:

“50% of all human disease is caused by water borne pathogens.”

“Just to make an ordinary bottle of water takes about 5 liters of water to make one liter of bottled water.”

“It takes 250 gallons of water going into a cow to make one quart of milk.”
