Researchers in China proposed a solar-driven integrated system that combines reversible heat pump and organic Rankine cycle ...

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 ...

According to holography, a black hole is dual to a thermal state in a strongly coupled quantum system. One of the best-known examples of holography is the Anti-de Sitter/Conformal Field Theory ...

Heat engines near the adiabatic limit typically assume a working medium at thermal equilibrium. However, quantum many-body systems often showcase conservation laws that hinder thermalization, leading ...

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 ...

Energy efficiency is becoming increasingly important due to rising energy costs, volatility in energy prices, and security of energy supply. Both the U.K. government and the European Union (EU) have ...

Power boost: a quantum heat engine in synthetic diamond. (Courtesy: Jonas Becker) Physicists have in recent years built a number of microscopic heat engines to investigate how the laws of ...
