Discover how to build a simple DIY Stirling engine powered by heat from candles using an empty spray can and pen components.

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 ...

China has built the most powerful thermoacoustic Stirling generator. The prototype delivered a groundbreaking 102 kilowatts of power from a heat source of 530 degrees Celsius (986 Fahrenheit). This is ...
