Understanding the Stirling engine: thermal energy in motion
How does it work, concretely? Simple: a small flame heats the air in a cylinder. That air expands, pushes a piston, which in turn drives a flywheel. And there, the motion begins. You have seen other models, but the arrow design brings a particular smoothness to the movement. It is fascinating to watch this energy conversion unfold. The little whoosh of the flywheel as it turns, the soft click of the parts… it has an almost hypnotising side. This object lets you show physics, not just read it in a book.
The perfect scientific object to give
Looking for a gift that will leave a mark? This red arrow Stirling engine is ideal for those thirsty to understand how things work. For a young scientific mind, it is an open door to physics. For a colleague? An original gift that will sit proudly on their desk. Watching it turn never gets old. It is more than an object, it is a conversation started, a spark of curiosity lit. And that is really something, isn’t it? You can already picture it on a shelf.

Graham Pettifer –
Engine itself is nicely made and it runs, but the instructions were only in German and French, which was a bit daft for a UK shop. Took me a good twenty minutes of fiddling with the flame height to get the flywheel going. Works now, just wish the leaflet had been in English.
Priya Nair –
Bought this for my desk at work and it’s a lovely thing to watch while the kettle boils. Smaller than I pictured from the photos, but the finish is neat and it ticks over smoothly once warmed up. Would’ve liked a spare wick in the box.

third thing I’ve ordered from here and it’s another good one. Packed well, arrived quick, and the engine runs for ages on a single bit of fuel. Bit pricey compared to some I’ve seen, but you can tell the parts are decent. Nephew’s already pinched it for show and tell.

My son, who is nine and normally glued to a tablet, sat there for a solid half hour watching the flywheel pick up speed. He kept asking how heat could make it move, so we ended up reading about the gas expanding and cooling in the cylinder and then he explained it back to me at tea. Brilliant buy, and the red paintwork looks cracking on his shelf.
Margaret Hollis –
Got this for my grandson’s birthday. His little face lit up when it started turning by itself. Lovely.

bought this for my grandson Alfie, who’s seven, and he sat glued to it for a good twenty minutes after we lit the little burner. “Nana, how’s it going round with no battery?” he kept asking me. Spot on, and he’s already told his teacher about it.
Daniel Whitcombe –
Brilliant little thing. The flame heats one side of the cylinder while the other stays cool, and that difference pushes the piston and keeps the flywheel turning, which is lovely to watch.
