What is the stirling engine? A Stirling engine is a heat engine that operates by cyclic compressionand expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall.
How it works? This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

This is a slick looking piece to have on your office desk and a great talking piece-- especially for engineers and mechanically minded people.
When it's up and running, it runs like a champ as per the other videos some reviewers have posted-- in fact, it runs so well it will sometimes try to wander if it is on a slick surface. However, put it on anything even slightly grippy and it stays still.
My only complaint is that the bottle is a little too tall (or the engine a little too low) and it takes a bit of tweaking to get things right and keep the flame lit. One other thing to note is that the base (which looks very nice) is sheet metal that is folded/bent into the shape you see. It is not 1/4" of solid metal is you might assume. Despite that, the base is very sturdy, not flimsy at all, and the overall appearance of the item is clean and professional.
I've been a collector of toy steam engines for over 35 years. 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.
This is a very elegant and smoothly functioning model Stirling engine. It is made of high quality components including a hardwood base, aluminum flywheels and heat displacer, and glass hot and cold cylinders which allow you to see the engine's parts move during operation. Replacement glass parts are included, but it would be nice to know that additional parts are available should they be needed. A small alcohol lamp is also included which provides sufficient heat to power the engine and burns 95% isopropyl alcohol effectively. The model arrived well packaged ahead of schedule. Overall, I have thoroughly enjoyed this beautiful and functional little desktop hot air engine!
