Abstract: A comparative analysis on thermodynamic efficiency based on maximum power & power density conditions have been performed for a solar-driven Carnot heat engine with internal irreversibility.

Harnessing quantum states that avoid thermalization enables energy harvesters to surpass traditional thermodynamic limits such as Carnot efficiency, report researchers from Japan. The team developed a ...

A recent study led by Chinese scientists has challenged the hundreds-of-year-old myth that a heat engine can achieve both maximum power output and high efficiency. The approach defies the foundations ...
