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 ...

The Stirling engine also needs the temperature gradient to work, but its design means that this can be much lower, so it can run by setting it on a nice cup of tea. That's because it can exploit very ...

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 ...

Aerospace engineer and content creator Tom Stanton has documented the step‑by‑step construction of a bicycle driven by a Stirling engine, a heat‑powered machine first patented in 1816. The 18-minute ...
