Twin Low Temperature Difference Stirling Engine 2 Cylinder LTD Stirling Engine Toy Gift
How does Twin LTD Stirling Work? Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and moves the air from the warm side to the cool side and back again over and over.

Great science toy for my kids. Something even my 9 year old daughter could operate. Just microwave two coffee mugs of water for two minutes, then place this on top of the mug. A slight touch to start its motion and off it goes.

Twin LTD Stirling
The craftsmanship is excellent. The choice of contrasting metal produce a pleasant visual effect. I have had minutes of fun and have enjoyed it mostly as a paperweight since the ease of operation is not so true. Scalding hot water will make the flywheel turn around for 3 minutes. Pretty but no so much entertainment.
