Hot Air Engine that Powers an LED This working Stirling engine model converts heat into mechanical motion and then into electricity. A spirit flame drives the piston, the flywheel spins up, and the onboard dynamo feeds a USB socket that lights the included LED lamp, making the full energy conversion visible in one desktop demonstration. How This Hot Air Stirling Engine Works The included alcohol lamp heats the displacer cylinder. Air expands, pushes the power piston, and turns the flywheel. A belt carries that motion to a small dynamo, which generates current at the USB-A output and lights the supplied LED lamp, so heat, motion, and electrical output are all observable on one running engine model. Zinc Alloy Construction The miniature engine is machined from zinc alloy with an electroplated gold finish. Precision bearings keep the flywheel turning smoothly through repeat runs, and the weighted base holds the metal engine model steady on a desk or lab bench. STEM Science and Physics Uses Classroom physics: demonstrate the Stirling cycle, thermodynamics, and heat-to-work conversion with a live running engine Laboratory experiments: observe energy transfer and compare flywheel speed at different heat inputs Home STEM learning: a hands-on engine model for students exploring mechanical engineering Desk display: a kinetic metal model for an office, study, or engineering collection Specifications Type: single cylinder Stirling engine model, hot air engine Dimensions: 6.5 x 3.7 x 4.5 in (16.5 x 9.5 x 11.5 cm) Material: zinc alloy with electroplated finish Color: gold metallic Heat source: alcohol lamp, included Electrical output: belt-driven dynamo to a USB-A socket, sized to run the supplied LED lamp In the box: Stirling engine, alcohol lamp, USB LED lamp Age: 14+, adult supervision required (open flame)
