Our Milky Way's halo of hot gas is warmer to the "south" than the "north" because of an internal combustion engine-like ...

Every night, the sky does something invisible and enormous. Heat escapes from Earth’s surface upward through the atmosphere and out into the cold of space.

Refrigeration is commonplace in the modern era. We use it to keep our food from spoiling, to cool our homes and workplaces, and to keep our car cabins from becoming saunas. There are even specific ...

We're not going to get into the whole "who made the first car" argument today. But there's not much doubt that the overall history of self-propelled vehicles goes back well beyond the Mercedes Patent ...

Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold of outer space. Using a special type of Stirling engine, ...

If you’re off-roading, it’s a neat idea to use your engine to top up your battery, which prompted Bluetti to launch the Charger. You could hook it to your alternator and draw off energy as you drove ...

This week, researchers from the University of California published a new study detailing an innovative approach to passive cooling. It can convert the Earth's passive heat into a small but steady ...

His Stirling engine was much safer because it worked on a different principle than steam. Instead of relying on the expansion of high-pressure steam, the Stirling engine is a closed system with a ...

Here’s what you’ll learn when you read this story: Continuing this millennia-long tradition, scientists at the University of California Davis have developed a kind of Stirling engine—first devised by ...

Exowatt believes it's struck upon a red-hot way to fuel all the world's new AI data center projects with affordable, scalable, and sustainable power: hot rocks. The technique leverages concentrated ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate power. Reading time 3 minutes Deep space may provide hidden sources of energy ...
