Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an ...

Gas engine-driven heat pump systems integrate a combustion engine with conventional vapor compression technology to provide heating and cooling while utilising waste heat recovery. These systems offer ...

“We’ve developed the world’s smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work,” said Clemens Bechinger, a physicist at the ...

A satellite image shows the huge snowstorm that blanketed the northeastern United States this week. The blizzard was an example of how storms are getting less common but more intense.

One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

Just how small can you make an engine? Two researchers from the University of Stuttgart and the Max Planck Institute for Intelligent Systems, Valentin Blickle and Clemens Bechinger, successfully ...

The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...

An innovative form of heat engine operates using only one single atom. An article in the latest edition of the journal Science describes an innovative form of heat engine that operates using only one ...

Quantum work: A quantum thermochemical engine operating in an Otto cycle with a weakly interacting 1D Bose gas as its working fluid. The initialization and exhaust strokes are performed by coupling ...

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 ...
