Demonic device converts information to energy

Nphys1821-F1

Demonic device converts information to energy @ Scientific American. Scientists in Japan are the first to have succeeded in converting information into free energy in an experiment that verifies the “Maxwell demon” thought experiment devised in 1867…

The laws of physics say that you can’t get energy for nothing — worse still, you will always get out of a system less energy than you put in. But a nanoscale experiment inspired by a nineteenth-century paradox that seemed to break those laws now shows that you can generate energy from information.

Masaki Sano, a physicist at the University of Tokyo, and his colleagues have demonstrated that a bead can be coaxed up a ‘spiral staircase’ without any energy being directly transferred to the bead to push it upwards. Instead, it is persuaded along its route by a series of judiciously timed decisions to change the height of the ‘steps’ around it, based on information about the bead’s position. In this sense, “information is being converted to energy”, says Sano.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
