This compact model demonstrates how heat from a flame can drive rotation, powering a flywheel and, in the LED variant, lighting up the scene for a dramatic hands-on science demonstration. Available in two configurations—No lights (no power generation) and With LED lights (with motor power generation)—this engine makes learning engaging, safe, and visually compelling. Model WD-01 is crafted with an aluminum alloy bottom and a quartz glass cylinder for clear, durable operation. \u003c\/p\u003e \u003cp\u003eWhether you’re a student, educator, collector, or curious hobbyist, this Stirling engine is perfect for scientific experiments, gifts, and interest research. Its compact size (165 × 85 × 10 mm) and light yet sturdy construction make it easy to display on a shelf or use in classroom demonstrations. The kit includes a large flywheel (49.43 mm) and a practical pulley (24.72 mm) to illustrate smooth rotational motion powered by heat.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment sold by InterCyprus to EU countries is CE certified and carries a two year warranty.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eSee real thermodynamics in action: turn the flywheel by hand to verify smooth movement before operation, then light the alcohol lamp and observe the engine begin to rotate after the warm-up.\u003c\/li\u003e \u003cli\u003e2 versions to suit your needs: choose No lights for a pure mechanical demonstration or With LED lights to enjoy motor-powered illumination as the engine runs.\u003c\/li\u003e \u003cli\u003eMaintenance tips: keep sliding parts clean and lightly lubricate both ends of the connecting rod (the piston itself should not be lubricated).
