This mini (beta) Stirling engine (high temperature run) is easy to assemble and take apart - had to build a new arm as it did not fix in place properly. CoOl test; to make it run with focused solar radiation.
Mini (beta) Stirling engine to add to my collection of devices/gadgets. Simple to assemble a few components; It is a heat engine that operates by cyclic compression and 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 engines heat flows in and out through the engine wall. 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 engines 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.
You can power it with the heat from your hand or some ice…
