Great, an micro Wankel engine. Did anyone else share my first thought, that this would be just right as the power source for a laptop version of Babbage's Analytical Engine? (My second thought was that an itty-bitty steam engine would be more appropriate). I wonder what the limiting factor would be? I suspect that the cube/squared law is involved - as the parts get smaller they cool down too quickly to operate as an engine. Peter Trei

Way cool tiny rotary engine for powering computers, whatever.
