Condition: Brand . Item Type: Stirling Engine. Material: Stainless Steel. Color: As picture. Overview This ready assembled Stirling engine converts heat into visible mechanical motion, offering a hands on way to observe how thermal energy is turned into work. The engine uses a small alcohol burner to heat the working gas. As the gas expands and contracts, it drives the internal mechanism and flywheel, producing continuous rotation and a built in LED light effect. Key benefits Clear demonstration of thermodynamic principles and engine operation for students, hobbyists, and curious minds. Ready to use out of the box; no assembly required so you can start experiments and demonstrations immediately. Durable stainless steel construction provides rugged, long lasting performance and a polished appearance. Includes fuel source and accessories needed to operate and display the engine. What you get 1 x Stirling Engine with LED Light 1 x Sponge 1 x Alcohol Cylinder 1 x Quartz Tube with Iron Wire How it works A small alcohol lamp heats the engine, causing the internal gas to expand. The expanding gas increases molecular motion and pushes on the mechanism. The flywheel smooths and stores motion so that thermal energy is converted into steady mechanical rotation. Observation of the motion helps build intuitive understanding of Stirling engine principles. Applications and use scenarios Classroom demonstration: Use as a visual experiment during physics or engineering lessons to illustrate heat engines and gas expansion. Science fair or project display: A practical project piece that shows real mechanical movement driven by thermal energy. Desk or shelf display for hobbyists: A compact, working model to demonstrate classic engine mechanics and spark curiosity.
