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

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

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 ...

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 ...

Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by ...

Deppe and Munday mounted a simple Stirling engine on a radiative cooling panel. They placed the setup on the ground, letting ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate ...

Engineers are using the temperature difference between Earth and space to power a low-temperature Stirling engine that drives ...

The model Stirling engine is a staple of novelty catalogues, and we daresay that were it not for their high price there might be more than one Hackaday reader or writer who might own one. All is not ...

In 1816, engineer Robert Stirling invented his proprietary Stirling engine, an automatic power source operated by ambient heat rather than direct fuel sources like an internal combustion engine. It ...

Earlier this week, we wrote about setbacks at some Silicon Valley companies with new solar technology. They’re built on real science and work in the labs, but they’re grappling with the real-world ...
