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 ...

Researchers created a microscopic version of the Stirling engine using a single particle. At such small scales, the random fluctuations of Brownian motion affect the position of the particle and the ...

Solar panels do a remarkable job during the day; however, the hours when people need the most electricity rarely coincide with the hours when sunlight is strongest. That mismatch has always created a ...

When the sun sets, the world’s solar panels go dark. But above them, the night sky radiates a different kind of power. Every night, as the world cools, Earth dissipates much of its heat into space.

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 ...

E-bikes and motorcycles are great, but what if there were another way to get moving? What if there were a motor that didn't require the combustion of Odin's juice to get moving? Well, there are plenty ...

Have you ever imagined a bike powered not by gasoline or electricity, but by the simple act of heating and cooling air? It might sound like something out of a science fiction novel, but the concept is ...
