Stirling engine model with hot air cylinder for physics demonstrations and science lessons

The Stirling engine is a collector's physics model designed to demonstrate the operating principle of a hot air engine at home, in the classroom, or in a science museum. This Stirling engine converts the heat from a spirit lamp into mechanical energy, which rotates the flywheel and visually reveals the laws of thermodynamics. A great gift for curious children, students, and technology enthusiasts.

Stirling engine - key features

• Real operating principle — The engine operates according to the actual Stirling cycle, allowing the user to observe the real conversion of heat energy into mechanical motion.
• Compact size — Its compact dimensions make it easy to place the model on a table, shelf, or use it as a demonstration tool in class.
• Transparent construction — Visible moving parts allow you to visually observe the interaction of the flywheel, piston, and test tube.
• Easy start-up — Simply fill the alcohol lamp, light it, and after a minute, turn the flywheel manually.
• Educational value — It is perfect for physics lessons, science projects, and popular science presentations.
• Collector's item — Its attractive design allows the model to be used as an interior detail or a gift for technology enthusiasts.

Technical specifications

• Product dimensions: 165 × 95 × 130 mm
• Approximate weight: 650 grams
• Fuel: alcohol (ethanol), concentration 95% or higher
• Alcohol lamp filling level: no more than 2/3 of the capacity
• Start-up time: approximately 1 minute after lighting the lamp
• Note: The buyer must purchase the fuel alcohol separately

Who is it suitable for and how to use it?

This Stirling engine is suitable for teachers, students, and technology enthusiasts who want to visually demonstrate the principles of thermodynamics. Before use, check that the flywheel rotates freely and that the moving parts are clean. Fill the lamp with alcohol, light it in front of the test tube, and after a minute, turn the flywheel by hand - the engine will start to rotate on its own. Be careful, as the metal parts get hot.

Buyer questions

Q: How to start the Stirling engine for the first time?
Turn the flywheel manually, check that the parts are clean, fill the lamp with alcohol up to 2/3 of its capacity, light it, and after a minute, turn the flywheel - the engine will start to rotate on its own.

Q: What fuel is required for the engine to operate?
95% or higher concentration flammable alcohol is required. The buyer must purchase it separately, as it is not included in the package. Fill the lamp carefully, without exceeding two-thirds of its capacity.

Q: Is it safe to touch the engine while it is running?
No, you should not touch the heated test tube or the metal parts connected to it - they get very hot and you could get burned. It is recommended to wait until the parts cool down.

This Stirling engine is an excellent investment in practical physics knowledge at home, in school, or in a collection. It is ideal for gifts and science demonstrations.
