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 ...

Scientists are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant. Scientists ...

(Nanowerk News) Classical motors convert a form of energy such as heat into mechanical work. Can these laws also be transferred to a miniature machine that consists of only a single cesium atom and ...

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 ...

As the world battles rising inflation, a cost-of-living crisis, climate change and more, it’s clear that the fossil-fueled status quo is not working. Fossil fuels may have seemed like the crutch we ...
