Thus, the Stirling engine, as described, realizes only a modest fraction of the Carnot efficiency. However, a relatively simple modification changes this picture.

We observe that Qa^0 = Qi^2. The heat that has to be removed from the gas in the 3 ^ 0 phase can be stored in a regenerator inserted in the pipe connecting the two cylinders, and it can be used to supply Qi^2. This means that the only heat required from the heat source is Q2^3 (500 J). Using a perfect, ideal regenerator, the efficiency of the Stirling cycle is

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
