How does a steam engine do work?

"Somebody claims to have developed a new reversible heat-engine cycle that has the same theoretical efficiency as the Carnot cycle operating between the same temperature limits. Is this a reasonable claim?"
Adi S.
In $1816,$ Robert Stirling, a Scottish clergyman, patented the Stirling engine, which has found a wide variety of applications ever since. Fuel is burned externally to warm one of the engine's two cylinders. A fixed quantity of inert gas moves cyclically between the cylinders, expanding in the hot one and contracting in the cold one. Figure P22.49 represents a model for its thermodynamic cycle. Consider $n$ mol of an ideal monatomic gas being taken once through the cycle, consisting of two isothermal processes at temperatures 3$T_{i}$ and $T_{i}$ and two constant-volume processes. Determine in terms of $n, R,$ and $T_{i}$ (a) the net energy transferred by heat to the gas and $T_{i}$ (a) the efficiency of the engine. A Stirling engine is easier to manufacture than an internal combustion engine or a turbine. It can run on burning garbage. It can run on the energy of sunlight and produce no material exhaust.
