Working Stirling Engine Generator Model with Light Bulb, Heat Powered Hot Air Engine, Dual Cylinder Metal Mechanical Desktop Physics Demonstration Model & Display Gift (Light Color Random)

This working Stirling engine generator model is a functional mechanical display designed to demonstrate the conversion of heat energy into mechanical motion and electrical output through a classic hot air Stirling engine system. When external heat is applied using the included alcohol burner, the engine’s dual cylinders begin operating, driving the pistons and balanced flywheel. The rotational motion powers the generator, illuminating the light bulb (light color random), allowing users to visually observe the complete energy conversion process. Constructed from durable metal materials and mounted on a polished gold-tone base, the model combines mechanical precision with refined visual appeal. Its open structure provides a clear view of the pistons, crankshaft, flywheel, and generator working together during operation. The model arrives fully assembled and tested, making it suitable for mechanical hobbyists and collectors seeking a ready-to-run demonstration piece. While the alcohol burner is included, fuel is not included and should be prepared separately (95% alcohol recommended). Ideal for desktop display, physics demonstrations, technical exploration, and personal collections, this Stirling engine generator model offers both educational value and mechanical artistry, making it a distinctive gift for science and engineering enthusiasts.

• 【Heat Powered Stirling Engine Generator Model】This working Stirling engine generator model demonstrates how heat energy is converted into mechanical motion and electrical output. When heated, the flywheel rotates smoothly and powers the light bulb, creating a clear and engaging physics demonstration. (Light color is random.)
• 【Dual Cylinder Design for Stable Performance】Featuring a dual-cylinder structure and balanced flywheel, the engine operates smoothly and steadily, allowing users to clearly observe the energy conversion process during operation.
