The extremely complex process of projecting future emissions of carbon dioxide could be simplified dramatically by modelling civilization as a heat engine. That is the conclusion of an atmospheric ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

BENGALURU: After years of struggle, a “micro heat engine”, that can produce maximum power at maximum efficiency, has been successfully designed by the Indian Institute of Science (IISc) and the ...

“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 ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

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

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