Physicists show Maxwell's Demon extracts more energy using hidden system memories

Bechinger team reports Maxwell's Demon extracts energy from hidden memories

Physicists at the University of Konstanz demonstrated that by exploiting information hidden in a physical system's memory, Maxwell's demon can extract more energy than a memoryless system. The team used a laser to trap a microscopic glass bead in a liquid filled with micelles—molecular structures whose movements were not directly observable—and by measuring the bead's position at carefully timed intervals around one second apart, they could infer the hidden network's dynamics and adjust the laser trap more effectively to extract energy.

“Information about a physical system can itself be used to extract useful work from that system.”
