Some engine designs fade into the background, quietly doing their job until regulations or fashion move on. Others keep ...

All real heat engines, be it conventional macro engines or colloidal and atomic micro engines, inevitably tradeoff efficiency in their pursuit to maximize power. This basic postulate of finite-time ...

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 ...

Residential homes and light commercial buildings usually require substantial heat and electricity simultaneously. A combined heat and power system enables more ...

Despite its critics and moves toward electrification, the internal combustion engine is not yet dead. Though its design for passenger vehicles may have begun to reach its apex with Mazda’s Skyactiv ...

Heat engines are thermodynamic physical systems that convert heat energy into mechanical work by exploiting a temperature difference between a high-temperature heat source and a low-temperature heat ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...
