A tiny, particle-sized engine that runs at temperatures approaching the innermost core of the Sun could open a window into ...

Solar panels do a remarkable job during the day; however, the hours when people need the most electricity rarely coincide ...

Researchers have created a device that generates mechanical power at night by harnessing the natural temperature difference between warm ground and the cold of outer space. Engineers at the, Davis, ha ...

Deppe and Munday mounted a simple Stirling engine on a radiative cooling panel. They placed the setup on the ground, letting ...

Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by ...

Quantum thermodynamics explores the fundamental principles governing energy conversion at the smallest scales, where quantum effects such as coherence and entanglement significantly influence the ...

THE working of exercises forms a very important part of the course work of an engineering student. Many of the exercises required for the purpose of elucidating the subject of heat and heat engines ...

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

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 Danish Technological Institute (DTI) has collaborated with Heatflow to demonstrate the use of metal AM to produce a ...
