*** WHAT IS STIRLING ENGINE *** 

Stirling engines are unique heat engines because their theoretical efficiency is almost equal to the theoretical efficiency, which is called the Carnot cycle efficiency.

The stirling engine generates power through gas expansion when heated and contraction when cold. This is an external combustion engine that continuously burns fuel, expands air (or helium or hydrogen) as a medium to move the piston, and cools the expanded gas in the cold cavity, repeating this cycle process
