- 09-04-03 Dean Kamen Invents Water Purifier (Truthtrek.com)
" 'In the emerging world, in the under-developed world, a gallon of water is so precious that without it, you're going to die,' he says. 'In some places, the average amount of time per day spent looking for water that's safe for their kids by women is four hours. And they carry this stuff, which weighs 62 pounds per cubic foot, four or five miles. And if it didn't turn out to be the right stuff, or they put their hands in it and contaminated it, they spend the next day or two burying the babies.' "
"Kamen began experimenting with a Stirling engine. The Stirling engine is named after its designer, Robert Stirling, a 19th Century Scottish minister. Basically, it is non-polluting device that plays heat against cold to create energy. It is a closed box with two chambers, one filled with gas."
"When the gas chamber is heated from the outside, with anything from burning wood chips to charcoal, the gas expands, creating pressure. That pressure drives a piston from the hot chamber into the cool chamber. In Kamen's design, that mechanical power achieves two goals: it creates electrical power, 300 continuous watts – enough to run a few electrical devices - and, as a bonus, creates enough heat to distill contaminated water, making it drinkable." 9-03
- 09-04-03 Dean Kamen Develops Sterling Engine (Truthtrek.com)
"Last year he also expressed interest in developing the Stirling for use as a 500-watt power generator and water purifier in developing countries. In explaining his 'Small is Beautiful' concept, Kamen has noted that more than a billion people in impoverished areas lack access to safe water. 03-06
- Kamen, Dean (Texas Instruments)
"Kamen sees the lack of appreciation for science in America as a problem - but that's not to say he's calling for a revamping of the educational system. In his view, more teachers, textbooks, PCs, and Internet access won't get students jazzed about learning. 'They need to have access to challenging, hands-on projects that result in a tangible product' - like building robots. And they need role models - engineers - to assist them." 03-06
- Students Compete in Robotics (PBS.org)
"This year, nearly 30,000 high school students experienced triumph and defeat in a national robotics challenge geared toward fostering an interest in math, science and engineering."
"Dean Kamen, Founder, FIRST: The skills these kids learn when they participate in FIRST give them career opportunities. Do you want to be an electric engineer, physicist? Do you want to do proteomics, or genomics, or nanotechnology? What exciting career do you want to go into? We're helping you make that option possible." 06-06
- Water Purifier for a Village (CNN News)
"Dean Kamen, the engineer who invented the Segway, is puzzling over a new equation these days. An estimated 1.1 billion people in the world don't have access to clean drinking water, and an estimated 1.6 billion don't have electricity. Those figures add up to a big problem for the world—and an equally big opportunity for entrepreneurs."
"To solve the problem, he's invented two devices, each about the size of a washing machine that can provide much-needed power and clean water in rural villages." Awesome Library does not endorse these products but provides them as examples. 08-07
- Water Purifier for a Village (RedFerret.net)
"Dean Kamen has unveiled the latest iteration of his power and water package for the third world. The two components are a water purifier called Slingshot that uses a fraction of the power of alternatives and a Stirling engine based power generator that works on cow dung." Awesome Library does not endorse these products but provides them as examples. 08-07
