What if you could draw energy from the night sky without effort? That's the question that researchers at the University of California, Davis are trying to answer with a new engine that generates power ...

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 ...

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 ...

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 ...

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 ...

I’ve always been intrigued by “small-scale” energy harvest where the mechanism is relatively simple while the useful output is modest. These designs, which may be low-cost but may also use ...
