A nanometre-scale engine without any moving parts can convert heat into electricity with an efficiency close to the limit dictated by thermodynamics. Heat engines harness the flow of heat from a hot ...

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 ...

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 ...

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 ...

For the first time, a quantum engine has outperformed its traditional equivalent, without any special tweaks to its environment. The device harnesses the weird physics of very small objects to produce ...
