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

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 ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate power. Reading time 3 minutes Deep space may provide hidden sources of energy ...
