Hot Air Stirling Motor Power Generator Alpha Engine Model Educational Physics Experiment Kit(B)

Really nice - high quality construction and it runs well!

Such a fun desktop device to fire up. Well built and works very well. Use 95% alcohol to power it.

Beautiful piece but They don’t work, will be returning.

Great Hobby engine. My teen son loves this. Runs really well. Excellent quality of item.

The media could not be loaded. It works. Actually generates 8V. Only run for very short time to avoid damage to the heat bulb. An extra glass bulb comes with the unit, a clue that it can be damaged. No idea where you'd get a replacement.Using 90% denatured ethanol. Burns clean and odorless. Pure grain ethanol is illegal in the state oh Ohio unless denatured. Sold as Klean Strip "Fuel".

Only bad thit is when you pick up the fuel and put it in the container it came with. The frame is so high if you don't have commonsense you will set the place on fire. Keep that in mind when purchasing

Bought this as a gift for my step father's retirement gift... he is an electrical engineer, and he really liked it. He shows it off all the time. It was a good gift

The materials are very much quality, can’t find a piece on it that seems cheap. Works well, and happy with the purchase.
