Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using ...

Two old ideas combine to create something new, and make a fully renewable mosaic even more efficient.

A tiny, particle-sized engine that runs at temperatures approaching the innermost core of the Sun could open a window into the smallest extremes of thermodynamics. By levitating a single particle of ...

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 ...

Professor Jeremy Munday has developed an experimental engine that can generate mechanical power from the temperature difference between the Earth and deep space when placed outdoors at night. The ...
