This beautiful and economical low temperature differential stirling engine is sure to attract attention! Attractive plated steel construction gives this engine a handsome appearance. Simply place it on a hot or cold surface (like a warm mug of coffee or water), wait for a few minutes while the heat is absorbed into the base plate, and then give the engine a gentle spin. Watch the engine perpetually turn, speeding up as more of the heat is absorbed through the base plate. Alternatively, the base can be cooled to make the engine spin in the opposite direction. The small footprint of this engine makes it ideal for situations where space is limited.

1. Simple Assembly
2. Small Footprint
3. Attractive Design

Product Dimensions:
Base Diameter: 4" / 100mm

    Quality. Poise. Elegance.

    Posted by Blake Riojas on Feb 16th 2017

    Materials, structural integrity, and mechanical design were absolutely flawless. As an engineer involved in K-12 education, I could not have been more impressed with the simplicity of this thermodynamics device. Also, its fluid motion and edgy design adds class to any atmosphere it's placed. While the price appears substantial for a simple Stirling Engine, it's actually the quality, poise, and elegance that makes it worth purchasing.

    Picture was not accurate

    The picture showed golden color plates. Ended up being a bit more silver. Works fine...
