Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Warming the cabin while the car is plugged in or idling saves energy and improves comfort. It also reduces windshield fog. So ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...

Quantum thermodynamics explores the fundamental principles governing energy conversion at the smallest scales, where quantum effects such as coherence and entanglement significantly influence the ...

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 ...

There are so many paths we humans are running down in our chase for a greener future it’s extremely hard to keep track of everything. The auto industry is trying to go electric, either by means of ...

A running engine produces heat, which expands its metal body, thereby increasing its compression ratio. This is true for ...

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 ...

Researchers at MIT have built a highly efficient thermophotovoltaic cell that, when paired with renewable resources, efficiently converts incoming photons—particles of light—to electricity. It’s an ...

A heat engine is a device that accepts heat from a high temperature reservoir, T H , performs externalwork, W, and rejects heat to a low temperature reservoir T L. The diagram shows a practical ...
