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

What if you could draw energy from the night sky without effort? That's the question that researchers at the University of ...

The engine is capable of producing hundreds of milliwatts per square meter, and scientists are already working on practical ...

Researchers have created a device that generates mechanical power at night by harnessing the natural temperature difference between warm ground and the cold of outer space. Engineers at the, Davis, ha ...

When placed outdoors at night, the device produces up to 400 milliwatts of mechanical power per square metre, enough to power a small fan or charge a motor ...

Solar panels do a remarkable job during the day; however, the hours when people need the most electricity rarely coincide ...

Abstract: This paper proposes a novel integrated multi-model optimization method to enhance the accuracy and practicality of motor structure optimization for free-piston Stirling generators (FPSGs).

A new device developed by UC Davis scientists works by taking advantage of the temperature difference between the warmth of the Earth and the extreme chill of outer space ...

Abstract: We report the design and microfabrication of a MEMS turbopump with thermal insulation, as the core component of a steam power plant-on-a-chip for waste heat recovery based on the Rankine ...
