Have you ever imagined a bike powered not by gasoline or electricity, but by the simple act of heating and cooling air? It might sound like something out of a science fiction novel, but the concept is ...

Many of us have read about Stirling engines, engines which form mechanical heat pumps and derive motion from the expansion and contraction of a body of air. A very few readers may have built one, but ...

Discover the fascinating world of engineering with our step-by-step guide on how to make a Stirling engine designed for low ...

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 ...

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 ...
