A Stirling engine converts heat directly into mechanical motion — no combustion, no fuel, just physics.\u003c\/p\u003e\u003cp\u003ePlace the engine on a cup of hot water and watch the flywheel spin. The temperature differential between the hot plate and cold cylinder drives a piston through a thermodynamic cycle — expansion, cooling, contraction, heating — just like in a real power plant, but visible at the scale of your desk.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you can demonstrate:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCarnot cycle and thermodynamic efficiency\u003c\/li\u003e\n\u003cli\u003eHeat-to-work energy conversion\u003c\/li\u003e\n\u003cli\u003ePressure-volume work and gas laws\u003c\/li\u003e\n\u003cli\u003eSecond law of thermodynamics\u003c\/li\u003e\n\u003cli\u003eTemperature gradients and heat flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e Polished aluminum and brass construction · Runs on 70°C+ heat source (hot water, candle, palm of hand) · Glass flywheel for internal visibility · Precision machined cylinder and displacer\u003c\/p\u003e\u003cp\u003eA favourite demonstration in physics labs from high school to university.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54140237119780,"sku":"GPP-STIRLING-ENG","price":79.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/stirlingkit-low-temperature-stirling-engine-motor-steam-heat-education-model-toy-9988542824512_800x_bdafd593-c833-421e-8ecb-6f09940c5d68.jpg?v=1780680353","url":"https:\/\/shop.goldenphysics.org\/products\/stirling-engine-model-thermodynamic-heat-engine-demonstrator","provider":"Golden Physics Project","version":"1.0","type":"link"}
