This little engine is lots of fun to play with. Build quality and performance are excellent and the little generator is fun to play with.
Magnificent Stirling engine! It is very well done. I only have one thing to limit, they should make a manual more understandable. But the engine is perfect!
Great little engine to demonstrate the physics of cool air expanding when heat is applied.
Beautifuly constructed engine that works very well. It had inspired me to build a 3D printed Stirling Engine. I highly recommend it for anyone be they collector or educator.
Super cool! Works great. I am studying thermodynamics and engine science for my Masters Degree and I used this working model to gain a better understanding of this working principle. The model works very well.
