A Stirling engine works with any external energy source heating the controlled volume gasses contained in the engine cylinder. As the gas expands from heat, it forces the pistons to move. Lots of math and physics later, you get mechanical energy at the crank. Traditionally the Stirling engine is used with waste heat for low speed, high power stationary applications, but Kamen's team has folded it into a hybridized Th!nk City as the on-board generator for the electric drive system.

Obviously the details on the DEKA Revolt are still murky, this is Dean Kamen we're talking about here. But the idea of a Stirling engine hybrid is intriguing. Because of its design Stirling's are inherently super efficient when talking about piston engines. Add to it the super-flexibility of the fuel source for the heat and you've got an equation which adds up to a great idea. Now, whether or not this thing actually comes to fruition or not is a whole different matter. [DEKA, FoxNews]

No idea, but if when completed, the car will sport the handsome and aggressive bodywork you see in these renderings along with an active air suspension, 19 inch wheels, six piston caliper brakes up front with four pistons in the rear and a steering wheel-mounted touch screen LCD to act as the control center for the car.

This may not be the first sports car from the land of the ice and snow, but it certainly is the most attractive we've seen from any automaker this side of the Iron Curtain. It's most definitely not as bad-looking as it's name might suggest. [Cardesign.ru (Translated)]
