Stirling Engine Model with Mini Generator Color: as shown Size: 16.5 x 9.5 x 12.5 cm Product overview This desktop Stirling engine model combines precise metalwork with a compact generator to demonstrate how heat is converted into motion and electricity. Constructed from zinc alloy and stainless steel with an electroplated finish, the model offers both durable performance and polished appearance. When heated by an alcohol lamp, the balancestructured engine runs steadily and produces enough electricity to light LEDs or small bulbs. Key benefits Clear demonstration of energy conversion: Shows the link between thermal input, mechanical motion, and electrical output, useful for teaching and handson learning. Reliable operation: Balance structure and quality components produce stable, smooth running when heated. Durable, attractive finish: Zinc alloy and stainless steel construction with electroplating resists rust and preserves surface texture for longterm use and display. Compact and displayready: Small footprint fits on a desk or shelf while serving as both an educational tool and decorative conversation piece. Ready for STEM projects: Integrates easily into lessons, science fairs, and hobby experiments. Features and specifications Materials: zinc alloy and stainless steel with electroplated finish Includes: Stirling engine with balance structure and builtin mini generator Heat source: designed to run when heated by an alcohol lamp Electrical output: sufficient to light LEDs and small lowvoltage bulbs Size: 16.5 x 9.5 x 12.5 cm Color: as shown Practical use scenarios Classroom demonstration: Use the model to teach thermodynamics and mechanical principles in physics or engineering lessons, providing a visible, handson example of energy conversion. Science fair or student project: Students can use the engine to demonstrate principles, collect observations on run time and output, and present a working model. Office or home display: Place on a desk or shelf as an elegant mechanical art piece that can be activated for short demonstrations or conversation. Who this is for Ideal for teachers, students, hobbyists, engineers, and collectors who want a compact, functional Stirling engine model that doubles as an educational device and decorative item. with schools and model engine enthusiasts.
