Tabletop experiments by Indian physicists have broken a barrier proposed 200 years ago by a legendary French engineer, Sadi Carnot, raising hopes of new high-efficiency heat engines hitherto ...

Ever since the invention of water mills in antiquity, through the development of the steam engine in the 18th century, and up to today’s turbines, many power generators rely on the principle of ...
