How a microscopic bio-heat engine works
Physicists have designed a microscopic heat engine by optically trapping a colloidal bead in a bacterial bath1. The heat engine could potentially be used in nano-electromechanical and microfluidic devices. A conventional macroscopic heat engine converts heat energy into mechanical work by confining a few cubic centimetres of gas between a moving piston and its walls.Read more about How a microscopic bio-heat engine works[…]
