(brief explanation) the monthly variation in the atmospheric heat engine efficiency on the QTP for May to September from 2000 to 2020. The atmospheric heat engine efficiency from May to September ...

This study was led by Prof. Xiaoqing Gao (Northwest Institute of Eco-Environment and Resources， Chinese Academy of Sciences) and Prof. Yaoming Ma (Institute of Tibetan Plateau Research, Chinese ...

(brief explanation) From the perspective of the spatial distribution, the Qaidam Basin was the region with a high atmospheric heat engine efficiency, reaching more than 2% in May and September, even ...

MIT says its new solid-state thermophotovoltaic heat engine can harvest more energy from heat than the average steam turbine, at a fraction of the cost and using no moving parts. Huge implications for ...

Challenging centuries-old assumptions about thermodynamics, a new study in published in Physical Review Letters has shown that it is theoretically possible to design a heat engine that achieves ...

People generate lots of waste heat. It makes sense that there is a desire to convert that heat into usable energy. The problem is one of efficiency. Researchers from MIT and the National Renewable ...

ON p. 326 of NATURE for August 29 appears an abstract of a paper by Dr. J. S. Haldane, which he read before the Institution of Mining Engineers on June 16. In this paper he has “thrown to the winds” ...

Researchers at MIT have built a highly efficient thermophotovoltaic cell that, when paired with renewable resources, efficiently converts incoming photons—particles of light—to electricity. It’s an ...

Diesel engines have been around since the late 19th century, which was around the time Karl Benz built the world's first automobile. Diesel engines have higher compression ratios than gas engines and ...
