Dean Kamen is famous for the invention of the SegwayW, the two-wheeled transport using a gyroscope for balance, and has also developed:
- The Slingshot water purifier
- Kamen's Stirling engine
- The iBOTW wheelchair based on the technology used in the Segway.
I thought the moral of the David and Goliath story was this little guy won because he had a really neat piece of technology.
