An Amazing Present for Engineers

Experience the magic of real engineering in motion!

This Mini Stirling Engine Model turns simple heat into smooth, rhythmic movement — a living example of thermodynamics brought to life.

Crafted from precision-machined brass and steel, it’s more than just a model — it’s a working engine that runs on the heat from an alcohol burner or even a tea light. Watch as heat becomes motion, and motion generates power through its built-in dynamo.

A perfect STEM learning tool, science demo, or collector’s piece, this elegant engine captures the beauty of physics, mechanics, and energy conversion in one mesmerizing display.

Whether for the classroom, office, or your home workshop, it’s a true conversation starter — and an unforgettable gift for engineers, students, or anyone with a passion for STEM. Find out more about this product in the dropdown sections below.

Frequently Asked Questions (FAQ)

Q: How does the Stirling engine work?
A: It runs on the temperature difference between its hot and cold ends. The expanding and contracting air inside pushes the piston, turning the flywheel to create motion. Check out the link in the "Links and References Section" below for more information.

Q: What fuel should I use?
A: Use methylated spirits (denatured alcohol) for best performance. A tea light candle can also work for a gentle demo. You can experiment with different fuel types for engine efficiency, power generation, etc. Be sure to thoroughly clean components if any soot-generating fuels are used.

Q: Does it generate real electricity?
A: Yes — the built-in mini dynamo produces small amounts of electrical power as the engine runs. The output depends on the heat applied, typically ranging from 2V to 5V DC at 10–50 mA. That’s enough to power a small LED bulb, as shown in the demonstration video in the image gallery on this page.

Q: Is it safe for children?
A: It’s intended for ages 16+, but can be used by younger learners under close adult supervision. Always handle with care and avoid touching the engine while it’s hot. The flame from alcohol burners can be nearly invisible, so use only in clear, open areas away from flammable materials such as curtains or furniture. We also recommend keeping a small fire extinguisher or fire blanket nearby as a precaution.

Q: How long does it run on one fill of alcohol?
A: Typically 5–10 minutes, depending on fuel amount, fuel type, and ambient temperature.

Nice

Quick delivery, good product.

Very happy

Super cool toy. Arrived in 28 days to my doorstep. As described.

Ingenious

The instructions are in English and Chinese, otherwise its ingenious

Nice thing

Stirling Engine Model is great :)

Mesmerising

Works great, even with a cheap candle. The generator produces around 1.2V max, so I recommend to add a Joule-Thief circuit to it. This way, just like in a bicycle, the Led flickers a bit but turns on directly. Build quality is really good, I can look at this for hours.
