Heat Goes In. Motion and Light Come Out.

Watch this video

A Stirling engine is the clearest physics demo there is. Light the alcohol lamp, wait a moment, and the flywheel starts to spin — heat becoming mechanical energy, right on the desk in front of you. This model goes one step further: the spinning engine drives a small generator and lights an LED, so the class watches heat turn into motion and then into electricity in a single, unbroken chain.

Why a Live Demo Beats a Diagram

Thermodynamics on a whiteboard is abstract. A flame pushing a piston is not. When students can see the cycle running and the LED glowing, energy conversion stops being a formula and becomes something they watched happen. That makes this engine a strong fit for physics lessons, lab sessions, and home experiments alike.

Where It Earns Its Keep

  • In the classroom: a live thermodynamics demonstration that holds attention
  • In the lab: observe the cycle and take measurements as the engine runs
  • For STEM programs: connect textbook physics to a working machine
  • At home: a hands-on way to spark scientific curiosity
  • On a desk or shelf: the golden metallic finish makes it a handsome display piece between demos

Built Like an Instrument

The body is zinc alloy with an electroplated finish, machined to tight tolerances so the engine runs smoothly demo after demo. A solid bearing system keeps the motion consistent over years of use, and the included alcohol lamp gives a steady heat source for fast, reliable runs.
