Palm Top Stirling Engine
Stirling Engine can work at very low temperature difference. This engine is running on PALMTOP! by using heat of Palm. Then temperature difference of it is 7K. This success is due to good sealing of power piston and reducing mechanical friction. In this engine, we have employed medical grass syringe as power piston. It has characteristics not only good sealing but also low friction. And pair of ball bearing is mounted to each end of crankshaft. The compression ratio must be down such kind of low temperature difference engine. It of this engine is about 1.01.
