In 1816, engineer Robert Stirling invented his proprietary Stirling engine, an automatic power source operated by ambient heat rather than direct fuel sources like an internal combustion engine. It ...

Not every building set has to be made from colorful plastic bricks. If you’re looking for something a little more challenging—and rewarding—than Lego, Hermann Böhm has created this gorgeous stainless ...

If you have never come across a Stirling engine, these fantastic pieces of engineering were first built in the early 19th century. The Stirling engine operates by cyclic compression and expansion of ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...
