Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large ...

Basically their theory is that thermoelectric conversion of heat into electricity can reach the Carnot limit and have some new computational modeling to guide development toward that goal and to model ...

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 ...

Prof. SUN Qingping (left) and Research Assistant Prof. LI Qiao (right), both from the Department of Mechanical and Aerospace Engineering at HKUST, demonstrate their newly developed Ti₇₈Nb₂₂ elastic ...
