1. This engine is a balance style, different from the ordinary Stirling model. Because of the heat from highgrade alcohol, the engine will run and create electricity. The power will go through the wire and drive the LED lighting. It's really interesting and imaginative toy. 2. 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 highprecision matchable components for smooth, reliable and longtime function. 3. This stirling engine is designed reasonable and compact. It adopts Lever mechanism and Crankrocker 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. 4. Fill the alcohol burner with 95% alcohol (recommended fuel) and light it. Let the light burn the round ended cylinder for about 60 120 seconds, then give the wheel a gently push, it will run well. With visual texture and aesthetic appearance, it's simply a piece of art.
