teriffic gift

I saw these on line a week before Christmas. Immediately I knew I would buy a few for some of my fellow engineers as thermodynamics makes the world go round!
All even arrived in time to give as gifts.
They fit perfectly over a normal coffee cup ( not mug) and a 1/2 inch of water in the microwave for 2 minutes is enough to provide several minutes of run time.
I have been using mine every day and i still am fascinated....fascinated to the point of purchasing a larger alcohol powered Sterling for a little experiment I want to try.

Thank for such an excellent product

Works beautifully, and is interesting to watch while working...

Assembly was very easy, and the instructions were very clear. I made a cup of coffee, and placed the engine on top of the mug. After a half minute or so, the engine responded to my moving the flywheel by continuing to spin on its own; it slowly gathered speed, and after about a quarter hour began to slow down (at that point my coffee was ready to drink).

A beautiful display of efficiency, this elegantly simple machine evokes perpetual motion.
