When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...
A VERY useful account is given in this book, from an engineering point of view, of the application of thermodynamics to the theory of the steam engine, mechanical refrigeration, steam nozzles, steam ...
Just how small can you make an engine? Two researchers from the University of Stuttgart and the Max Planck Institute for Intelligent Systems, Valentin Blickle and Clemens Bechinger, successfully ...
Research from The University of Manchester has thrown new light on the use of miniaturised 'heat engines' that could one day help power nanoscale machines like quantum computers. Heat engines are ...
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 ...
The most comprehensive sci-tech news coverage on the web ...
The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...
One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...
