Stirling Engine Desk Model with Alcohol Lamp Color Type 1 Key benefits Demonstrates the Stirling engine principle in a compact, visual format suitable for education and display. Runs using a small alcohol lamp included in the package, requiring minimal heat input to operate. Durable construction and refined finish make it both an attractive desk piece and a reliable working model. Encourages handson learning, manual dexterity, and spatial reasoning through assembly and operation. Features Materials: stainless steel, aluminum alloy, and reinforced thickened glass for the heating cylinder. Precision components: brushed aluminum alloy base plate, aluminum alloy flywheel, stainless steel connecting rod, and aluminum alloy power cylinder sleeve. Heating cylinder made of reinforced glass designed to withstand prolonged heating during operation. Compact size: 16.5 x 9.5 x 13 cm; weight: 800 g. Designed for hobbyists, students, and educators looking for a tangible demonstration of thermodynamic motion. How it works Based on the Stirling principle, the model converts heat from the included alcohol lamp into mechanical motion. The heat source warms the glass heating cylinder and drives the piston and flywheel assembly, showing the engine cycle in action. Requires basic patience and handson skill to operate and maintain, making it suitable as a learning tool. Practical applications and use scenarios Classroom demonstration: Use in physics lessons to illustrate heat engines, thermodynamic cycles, and energy conversion. Handson hobby project: Assemble and operate as a desk model for mechanical enthusiasts and model builders. Office or study display: Run as a visual conversation piece that demonstrates a classic mechanical principle.
