It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

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 ...

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 ...

“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 ...

One of the basic truths learned in college thermodynamics courses is that no heat-activated cycle can be devised that is more efficient than a Carnot cycle operating between the same temperature ...

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 ...

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 ...
