In the early years of the nineteenth century, steam engines were at work in a variety of practical uses. However, they were still imperfect in many ways. One particular problem were the boilers, that ...

His Stirling engine was much safer because it worked on a different principle than steam. Instead of relying on the expansion of high-pressure steam, the Stirling engine is a closed system with a ...
