MIT says its new solid-state 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 ...

Physicists successfully created a working heat engine that consists of only one atom. When built on a larger scale, the output of this single-atom engine could replicate the one from a car engine.

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 ...

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