This is a fairly basic Stirling engine. Place it on top of a cup of hot water, or, a cup of ice water, and away it goes. As long as the temerature differntial is sufficient, this engine is well made enough and well balanced enough, that it works very well. A great intro to the concept of heat exchange, for a school project, or merely as a conversation piece.

Bought it for my husband as a birthday gift and he LOVED it! It was his favorite gift. Now everyone in the family knows what a sterling engine is and how it works.

This little engine arrived promptly, and it worked right out of the box from the heat of a cup of hot water. To anyone unfamiliar with Stirling engines it looks like magic. I highly recommend it.

Hi, I love to see kids learn to think, and wonder about the world we live in! To see a Stirling engine run on nothing except a heat differential is really thought provoking. It could also be made to run with focused solar for a heat source. I'm 60 now, and never get tired of showing these kinds of displays of physics, and natural science to youngsters, and anyone else interested!
The product is well made. Tolerances and balance need to be very close for this to work. It's attractive to look at as well.
Great gift, or desk ornament! Also, it came very well packaged and damage free.
Really like this!
