I actually caught this last week on 60 Minutes II and was seriously impressed. Dean Kamen showed that he is well on the way to be able to build a Stirling engine. What is so amazing about his thinking is that the device would be able to provide enough power to: enable computing devices; recharge a Segway HT and clean water that may have been collected. This could all happen simply by burning wood chips or any other readily available resource. Dean sees and it is hard to debate on this one, that the world could forever change with this device. Third world countries depending on water for survival would be able to have a quicker way to get the water (segway) to and from the source, plus a way to clean it for safety. Clean energy and clean water, not bad for a guy who dropped out of school…
