Maxwell’s demon invoked on the largest scale yet.

A recent article in New Scientist discusses a chemical pump that has been designed based on a thought experiment known as Maxwell's demon. Physicist James Clerk Maxwell theorized this experiment in 1867, which involved a demon controlling the movement of particles between two boxes of gas. The pump, created by Jonathan Nitschke and his team at the University of Cambridge, uses a light-sensitive chemical to transport molecules from one side of a U-shaped tube to the other. By shining light on one side of the tube, the chemical changes its configuration and accumulates on one side, allowing for the separation of chemicals in industries such as drug manufacturing.
