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.

Why Buy Enginediy Twin LTD Stirling?
1, Creative Design : Twin cylinder low temperature difference Stirling engine
2, High Craftsmanship: Amazing mechanism linking the cylinders. The base made from aluminum alloy (after sandblasting and black oxide process), metal flywheel (with nickel plating process) , brass cylinder block. Overall, highly craftsmanship.
3, Eco-friendly: Low Temperature Differential Stirling Engine is the ultimate eco-friendly device, showing with one spin of the flywheel a clean and simple way of converting waste heat into motion. Because these engines rely on a temperature difference for operation, they will run on almost any source of warmth. Typical heat sources include hot coffee or tea, warm sunlight, CRT monitor, TV digibox, ect.
4, Easy Operation: Place the base on the cup with hot water. After preheating for more than ten seconds, use the flywheel to assist the engine and the engine will run by itself.
5,Great Gift Choice : it will be a remarkable gift for anyone interested in science; a great conversation piece that could be used as teaching tool on demonstrating physics knowledge; enable kids to think about basic principles of the universe. Especially for those who owned Stirling engines before, you should try this one and I guess you’ll not feel regretful.

“The little engine that can.“ It works nicely over heated water and is great fun. Excellent application of thermodynamics and mechanics, for young and old.

fun to watch

I bought this to show kids a simple machine that runs with no electricity. It functions well and I enjoy it.

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.
