Usmile® Low Temperature Stainless Steel Stirling Engine Generator Desk Models Education Toy Model Run Off The Temperature Difference

This low temperature stirling engine,runs on a hot cup of water(Do not put it above a candle or other fire)
The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. In the case of using a cup of hot beverage, not only is the engine transferring the beverage's heat to the surrounding air, there are air currents constantly crossing the top (cold) plate. The differing temperatures will cause the engine to slow or speed according to the net difference between the two plates. For some extra fun, you could obtain a USB-powered cup warmer and place engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ.

Attention:
1.If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely.
2.Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy.
