The power will go through the wire and drive the LED lighting. It's really interesting and imaginative toy. 🥇The main body of the stirling engine is made of zinc alloy materials in electroplating process for rich metallic luster and enhanced industrial texture, featuring high-precision matchable components for smooth, reliable and long-time function. 🥇This stirling engine designed reasonable and compact. it adopts Lever mechanism and Crank-rocker Mechanism, it looks more Mechanical and cool. This machine contains pattern of connecting rod piston, crankshaft, lever, belt drive, gearing, worm drive, transmission, threaded fastener, rolling bearing, plain bearing, heat transfer, sealing techniques etc. 🥇Fill the alcohol burner with your 95% alcohol (we recommend this fuel) and light it.
