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 ...

Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think ...

UC Davis engineering 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 ...

One of the basic truths learned in college thermodynamics courses is that no heat-activated cycle can be devised that is more efficient than a Carnot cycle operating between the same temperature ...
