From the Man Who Brought You the Segway: The Next Electric Car?
Remember the Segway? Back in 2000, the self-balancing scooter was hyped as the Second Coming of wheeled transport. Unfortunately for its inventor, eccentric New Yorker Dean Kamen, it hasn't really caught on outside a narrow circle of enthusiasts. But Kamen doesn't care. He's got something better:
Conceived in Scotland almost 200 years ago, the Stirling is a marvel of thermodynamics that could help to replace the internal combustion engine—in theory it can turn any source of heat into electricity, in silence and with 100 percent efficiency. But corporations including Phillips, Ford and Nasa have devoted decades of research, and millions of dollars, to developing the engine, and all retired defeated, having failed to find a way of turning the theoretical principles of the engine into a workable everyday application.
After ten years and a $40 million investment, Kamen and his engineers think they've succeeded where NASA failed. Though the Stirlings aren't ready for commercial use, Kamen says he's test-driven engines burning everything from jet fuel to cow manure. They don't work in cars yet, he says. But they will.
