DjuiinoStar High Performance Low Temperature Stirling Engine
★EASY TO PLAY this engine is powered by the temperature differential between the top and bottom panels. Just take it out of the box and put it on a mug of hot coffee, wait for seconds, then give the flywheel a gentle turn and you're up and running! The start temperature differential between the two panels is around lower than most of the engines on the market. ★STIRLING ENGINE OF HIGH PERFORMANCE compared with traditional engines, this one runs smoother and is stabler use hardened power piston(less friction & unbreakable); stainless steel string as connecting rod connecting the flywheel and the power piston(less friction); two little magnets on the power piston and displacer interact with each other as connecting rod to minimize mechanical
