Heat engines convert heat into work—for example, moving a piston in a certain direction. For an engine to be 100% efficient, when the process is reversed—the piston returns to its original state—there ...

As the world battles rising inflation, a cost-of-living crisis, climate change and more, it’s clear that the fossil-fueled status quo is not working. Fossil fuels may have seemed like the crutch we ...

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...

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 ...

MIT says its new thermophotovoltaic heat engine can harvest more energy from heat than the average steam turbine, at a fraction of the cost and using no moving parts. Huge implications for future ...

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