A Stirling engine is an external combustion engine that runs on the expansion and contraction of gas within a sealed system. In this video, we break down how it works, from heating and cooling cycles ...

Refrigeration today is something we can easily take for granted. But in the early 1800s, there was one entirely different ...

The Stirling engine also needs the temperature gradient to work, but its design means that this can be much lower, so it can run by setting it on a nice cup of tea. That's because it can exploit very ...

Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold of outer space. Using a special type of Stirling engine, ...
