Stirling Engine Demonstration Model with Lamp and USB Light Product overview A compact metal Stirling engine model designed for demonstration, display, and handson learning. The engine operates with external heating, converts heat to mechanical motion, and can drive a small lamp. Precision components and metal construction provide reliable, observable operation. Key benefits Clear demonstration of thermodynamic and mechanical principles: shows cyclic expansion and compression of gas and direct energy conversion from heat to motion. Ideal for teaching or selfdirected learning. Visual and practical: runs at speed under a heat source and can light the included bulb, making the conversion process visible in both bright and dark environments. Durable and refined construction: main components are zinc alloy with electroplating for a metallic finish and improved industrial texture. precision parts support smooth and consistent operation. Ready to use: includes a lamp and a USB light to provide the required heat and illumination. An introduction guide is included to explain basic operation and setup. Specifications Material: Metal (main body zinc alloy, electroplated) Product dimensions: 16.5 x 9.5 x 11.5 cm Product weight: 650 g Package dimensions: 20.5 x 11.5 x 18.5 cm Package weight: 950 g Packing: Graphic Carton Package contents Stirling Engine x 1 Lamp x 1 USB Light x 1 Introduction x 1 Performance and function Closedcycle reciprocating engine design: external heating causes cyclic gas expansion and compression at different temperatures, driving the piston and flywheel. Can reach rotational speeds when heated and produces enough mechanical energy to illuminate the included bulb during operation. Precision matched components ensure smooth motion and extended operating life with appropriate use. Use scenarios Classroom demonstration: show the Stirling principle and basic thermodynamics in physics lessons or lab sessions. Laboratory and experiments: use as a handson device for experiments on heat engines, energy conversion, and mechanical systems. Desktop display or gift: attractive electroplated metal finish makes the model a functional desk ornament and an instructive gift for hobbyists and students. Notes for use Operates when heated by the included lamp; observe recommended safe handling and placement during operation. Follow the included introduction for setup and basic operating guidance.
