Scientists in Sweden experimentally evaluated a Stirling engine–based Carnot battery (SECB) prototype using low-cost sand as thermal energy storage, aiming to validate ...

Heat engines are ubiquitous as they lie at the core of cars, aircraft, refrigerators, power plants and miniature motors. But they are currently limited by Carnot's maximum efficiency rule, according ...

“We’ve developed the world’s smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work,” said Clemens Bechinger, a physicist at the ...

Airthium, a clean technology company based in Austin, Texas, has developed an innovative heat engine designed to replace fossil fuels and decarbonize industrial heat and power generation. The company ...
