I really did not know much about engines that run on air, nor did I care. But I decided to try one out of curiosity. WOW !! What an engine. It literally runs at warp speed. Just give it some denatured alcohol and a light lubrication and it will run like blazes after only 30 seconds of heating up. Two cautions though: avoid using rubbing alcohol because of its impurities, and hold on to it because it will want to fly off the table if you leave it to its own devices ! Hope you have as much fun as I have. I am planning to buy a different model next month. This item shows high quality workmanship and is worth the financial outlay. Please note that this model has nothing to do with electricity of the generation of such. That's an error in the description and really pertains to other models from this manufacturer. ### ⭐⭐⭐⭐⭐ Awesome little engine that can! We love it! *by J***N on Reviewed in the United States on August 1, 2018* I can't say enough about this little engine! I have a 7 and 9 year old. My father stops by too and we all love to watch this engine run! Oh! I had read reviews that said how terrible it was to get the wick in the burner cap. Simply loop a twist tie and use it to pull the wick through, simple and fast.Out of the box the engine ran fine with a fairly large flame but noticed a squeak. The instructions that came with it explained how to oil the pivot points and now I have the wick pulled back to small flame that barley touches the glass and the engine runs quiet and smooth! Personally It's memorizing. I would certainly recommend this to anyone that likes mechanical things. ### ⭐⭐⭐⭐⭐ PLEASE READ MY REVIEW!!!!!! *by J***D on Reviewed in the United States on August 7, 2014* I bought this little engine on July 29 2014 I picked standard shipping and it arrived to my door about 2:30 in the evening on August 6 2014 in two boxes It was packed pretty well I got it out nothing was broken it came with two cylinder glasses and the cold air piston sleep in a bubble wrap and some tools to take it apart if needed it's about five inches in length 3 inches in width in my opinion it is a very nice piece and fun to run I run it on 91% rubbing alcohol and it doesn't leave any oily grease on the glass tube I was very happy with it I run it almost every day I would definitely recommend to a friend your not wasting your money the only thing I did was oil the bearing cause they had a slite squeak but by oiling them that fixed it definitely earned 5 out of 5 ratings --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/6146320-sunnytech-hot-air-stirling-engine-education-toy-electricity-power-sl01m](https://www.desertcart.tn/products/6146320-sunnytech-hot-air-stirling-engine-education-toy-electricity-power-sl01m) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-29*
