"Fast & Furious"
David Szromba✓ Verified Purchase•October 24, 2023
Since I am not new to Stirling model engines, I realize that each one comes with its own personality. This
Sunnytech Air happens to be "fast and furious!" It lights the variable color LED with ease. While running, this LED changes to several different colors. It's fascinating to watch the engine run through the glass cylinder, but even more interesting because it's turning a power generator to make the light work.
I have other Stirling and steam engines of which some can't get out of their own way, others that run about average and a couple that are very temperamental.
I didn't expect to fill the burner (with denatured alcohol) and just watch it go. I at least thought I would have to lubricate the moving parts before seeing good runs. However, right out of the box, it runs great! B.T.W., these little mechanical devices should be lubricated with dry graphite lubricant, as used with the Pinewood Derby Race cars. A little is much better than too much. Hopefully, this will be expressed in future running instructions.
I am grateful that the wood base was left unfinished. Now I can stain it the color I prefer.
It's my intention to mount all my Stirling engines on a shared display and running board. This way I'll be able to run one or all of them at the same time. When I complete this display, I will make a video of them and upload it to YouTube. If interested, you may view one of my Steam Plant Builds on YouTube now at this address;

Excellent little engine for the price. Mine worked perfectly. Vibrates. Great for technology demo.

Amazing little gadget.
The engine was well packed in bubble wrap and tape. Too much tape, but OK. There were instructions, written by someone whose third language was Klingon and maybe English was their fifth language. But they could be comprehended, and they really were not needed. The engine was completely assembled, except that (1) the glass hot cylinder was not installed. There is a spare. (2) the wick was not installed in the Alcohol lamp.
I installed the wick (it helped to wet it with alcohol and rub it to a point) then put 70% isopropal alcohol into the bottle, lit it, and in under a minute. it was working.
It ran for about 10 minutes and then ran out of alcohol. There was plenty of power to run the generator, and to shake the thing.
That was the only issue with the thing, it vibrated enough to walk around and around. I had to hold it to keep it from walking on to the floor. I needed to check something, so I had to carry it. Walking around cooled the hot cylinder too much. Soon as I put it down it started running again.
For the price I am completely satisfied with this item. I am amazed that the air can actually heat up and cool that quickly, but obviously it can. I am somewhat surprised at the power of the air heating and cooling. This is physics that you can touch. I hope my grandkids get it.
The box contained:
1. The Engine assembled and mounted on the piece of wood. It was attached to the generator.
2. Spare O-rings. There were two spares, and the seal is 3 o-rings.
3. two glass hot cylinders, one is a spare.
4. The tiny alcohol lamp. Separate wick, Separate cork.
