MBCook writes "CNN has an article in which they talk about Dean Kamen's latest inventions designed to provide water to rural villages. His goal is also to provide electricity and opportunities for entrepreneurship. From the article: 'Eighty percent of all the diseases you could name would be wiped out if you just gave people clean water,' says Kamen. 'The water purifier makes 1,000 liters of clean water a day, and we don't care what goes into it. And the power generator makes a kilowatt off of anything that burns.'"
