MANCHESTER – The same day that Ford and General Motors announced catastrophic third-quarter losses, Dean Kamen was showing off his new electric car.
The prototype vehicle, a zippy two-seat hatchback designed with more than a passing resemblance to the Volkswagen Beetle, can go about 60 miles on a single charge of its lithium battery and with practically zero emissions.
The secret?
"It's the world's first Stirling hybrid electric car," its inventor said with a flourish.
Installed in the car's trunk compartment is a Stirling engine invented at DEKA, Kamen's technology company in the Manchester Millyard. It powers the features that would normally drain huge power from the battery, notably the defroster and heater.
That leaves the battery primarily for propulsion. "You're running a pure electric, which is enormously cheaper to operate and enormously more environmentally friendly," Kamen explained.
And if the battery does run low, the Stirling can recharge it, so you'll never get stranded, he said. That's why Kamen calls his Stirling engine "an insurance policy" for the electric car.
Kamen showed off his state registration for his new car, listed as a 2008 DEKA Revolt. "I'm a car manufacturer!" he grinned. "It's so exciting!"
