Product Review

What you are looking at is a Hot Air Stirling Engine Assembly Kit. It will cost you about 30 minutes to assemble. After that, fill the tank with alcohol (not provided; purity >= 95% is suggested; search "Denatured Alcohol" on Amazon you will find a lot); preheat 30 seconds; give the flywheel a gentle turn, then it will run by itself. Plesae note this is a DIY product. One step wrong, engine might will refuse to work. If so, please contact us for replacement to try again. Thank you.

Main parts of the engine are not treated, you can paint them with color you like. You can also facilitate the groove on small flywheel to output energy generated. DIY.

This kit is suitable for one interested in physics/mechanics or engines. By assembling/dissembling/debugging, you will understand basic structure of a Stirling Engine. DjuiinoStar stand behind its products, buy with confidence.
