Completely assembled, Vacuum engine, Sucks a flame into chamber provide power. Hence the name flame eater. Similar in cycle to a Stirling engine. Remember when you were in school and taught about internal combustion engines? Well a vacuum Engine uses external heat to generate power. Like toys that are hard to explain and amazing to watch? Like precision pieces of equipment that are beautifully engineered? Love science? Want a gift for the person that has everything? If so you will want a Stirling Engine.The engines I offer are fully assembled and not a kit.This version uses a small flame to provide heat the to the "expansion chamber". it is a very durable design that should last a long time. it comes with a few spare parts in case you need them .If you would like to see a video of them operating look at You tube and look DStar Vacuum Engine. I am sure you will want one. All my units I sell are personally tested by me (Dstar engines "Star Power") to make sure they work. A full warranty and phone support is offered if you need any help with your engine.

A little frustrating and temperamental, but that is typical of this type of engine. If it ran smooth out of the box, I would give it five stars. But then on the other hand, I wouldn't have anything to think about. Overheating becomes an issue when I do get it to run for a sustained length of time. It's worth the effort of "man" vs. "machine" ;-)

And excellent engine model at a great price
Full disclosure for me: I own a science toy store and have been able to review several of these engines.The flame eater/vacuum engine is a great demonstration. I was able to get it running with just some 91% rubbing alcohol in a few minutes. The biggest starting issue was properly positioning the flame.The engine looks great, is well built, and has a very 'steampunk' look to it. It is slightly smaller than the other Stirling/heat engines offered by DStar but still gets quite a bit of spin in its wheels. The best part is you can watch the flame being 'eaten' by the engine.Although the engine does run on 91% alcohol you may wish to use a more pure alcohol as the rubbing alcohol I used did cause some seemingly random slow-downs and speed-ups. This could actually be used by a clever teacher as to being similar to what happens when you use low-octane fuel in a sports car engine.DStar tests its engines before they leave so take note that there may be some flame markings on the engine. This probably cannot be avoided but prevents any defective models from being shipped. Just keep it in mind.Overall, this model works great and is good for school or hobby.
