History

The Stirling engine was improved by the Scottish minister Robert Stirling in 1816, aided by his brother engineer. They intended to replace the steam engine, which the Stirling engine is very similar to structurally and theoretically.
 

In the early nineteenth century, the steam engines blew up very often, due to poor metallurgical technology of the boilers, which broke when subjected to high pressure.

Sensitive to the pain of the families of workers killed in accidents, the Stirling brothers seeking to devise a more secure mechanism.
