Stirling Engine Model — Thermodynamic Heat Engine Demonstrator

Watch thermodynamics run in your hand. A Stirling engine converts heat directly into mechanical motion — no combustion, no fuel, just physics.

Place 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.

What you can demonstrate:

• Carnot cycle and thermodynamic efficiency
• Heat-to-work energy conversion
• Pressure-volume work and gas laws
• Second law of thermodynamics
• Temperature gradients and heat flow

Specifications: 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

A favourite demonstration in physics labs from high school to university.
