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 ...

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 ...

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?
