Stirling Engine With Alcohol Heat Source Fully Assembled

Stirling Engine Kit – DIY Steam Power Motor Model | Educational Heat Engine Toy with Generator Output

This Stirling Engine Kit is a fully functional external combustion engine model that runs on heat from a simple alcohol burner. A powerful educational tool and engaging hands-on model, it demonstrates thermodynamic principles using a quiet, efficient, and beautifully crafted system.

How It Works
The Stirling engine operates by cyclic expansion and contraction of gas—such as air—within a sealed chamber. Heated by an alcohol lamp, the air expands, pushing the piston; it then contracts as it cools, creating a continuous cycle of motion. This simple, elegant process is based on the Carnot cycle and is one of the most efficient heat engine designs.

Operating Instructions

Place the engine on a level surface.

Check that all rods and pivots move smoothly; clean any oil or dust if needed.

Fill the alcohol burner (no more than two-thirds full) using 95% purity alcohol (not included).

Light the burner and allow the engine to heat for 1–2 minutes.

Gently spin the flywheel to start the motion.

Attach an LED to the generator output terminals to see electrical generation.

Safety Notes

Do not touch hot surfaces during operation.

Avoid over-tightening any glass components.

Keep wicks away from direct contact with glass parts.

Use only appropriate alcohol fuel in a safe, ventilated environment.

This elegant Stirling engine makes science hands-on and memorable. Whether you're an educator, student, collector, or simply curious, it's a rewarding way to explore real mechanical energy conversion.
