E-bikes and motorcycles are great, but what if there were another way to get moving? What if there were a motor that didn't require the combustion of Odin's juice to get moving? Well, there are plenty ...

Engineers at the University of California, Davis, have built a small device that produces mechanical power at night by exploiting the contrast between ambient warmth and the extreme cold of outer ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

Here’s what you’ll learn when you read this story: Stirling engines, which have been around for centuries, leverage temperature differentials in a gas to do light mechanical work. A new study ...
