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 ...

A satellite image shows the huge snowstorm that blanketed the northeastern United States this week. The blizzard was an example of how storms are getting less common but more intense.

A nanometre-scale engine without any moving parts can convert heat into electricity with an efficiency close to the limit dictated by thermodynamics. Heat engines harness the flow of heat from a hot ...
