This Stirling engine model can clearly explain the principle of thermodynamics.
Features: 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.
