QDoes this product have a built in motor that produces electricity?
AFeatures: A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. Teaching will be more intuitive and more interesting. Student can understand it quicker and better. The assembly process is quick and easily.
This is a nifty contraption that my was a gift for my dad and he enjoyed very much. I still hear him letting this run in the background several times a day. I'm most impressed with the fact that this thing is able to keep on going for maybe hours now (?) without any oil or problems. This is one of the more affordable versions I initially found and there are actually many other versions but I think this one runs high on the value scale.
