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 ...

Discover how to build a simple DIY Stirling engine powered by heat from candles using an empty spray can and pen components. This step-by-step guide demonstrates how to construct the engine, build a ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

Wrap the copper tubing around the burn chamber to add even more heat-capturing surface area. Concentrate the coils around the bottom third of the chamber to gain the most heat. My wife and I designed ...
