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 ...

A tiny quantum machine can release light that is not simply wasted heat; some of that energy may still be useful for doing work. University of Basel physicists found that separating orderly, coherent ...

A tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly difficult question: what counts as heat, and what energy can still do useful work ...

The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins ...

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 ...

A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate ...

Here’s what you’ll learn when you read this story: Scientists created an engine made of only silica particles suspended an electric field, and cranked temperatures up high enough to rival the Sun’s ...

Hypersonic propulsion requires precise management of extremely high temperatures and pressures to maintain engine performance and structural integrity. Thermodynamic optimisation in this domain ...
