Thanks to the rise of intermittent renewable energy sources, we’ve seen increased demand for new energy storage technologies, like batteries, pumped storage hydropower, and flywheels. But what if I ...

A Stirling power converter is a machine that converts heat into electrical current, a possibly game-changing device for spacecraft and space colonies. NASA has been developing its own Stirling ...

A hot air or Stirling engine runs without carburetors, injectors, cams, valves, timing chains, spark plugs, or anything. It’s incredibly simple and can even be emissions negative, running on waste ...

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 ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

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 ...

China has revealed what it claims to be the world's inaugural microwave weapon cooled by a Stirling engine. This innovative high-power microwave (HPM) weapon, reportedly powered by four Stirling ...
