A circuit invented that generates pure, limitless energy from graphene

Physicists have developed a circuit capable of capturing the thermal motion of graphene and converting it into low-voltage electrical current.

This energy harvesting mechanism contradictsRichard Feynman's assertion that Brownian motion cannot do the job. However, a team at the University of Arkansas found that the thermal motion of graphene at room temperature can actually generate alternating current in the circuit.

To do this, scientists built a circuit with two diodes to convert alternating current to direct current.The diodes are located opposite each other, whichallows current to flow in both directions, provides separation of its paths, creating a pulsed DC current that does work on the load resistor.

The team also found that the behavior of the diodeswhen switching on / off and switching, increases the supplied power, and does not reduce it, as was previously thought. To prove this phenomenon, scientists relied on the nascent field of stochastic thermodynamics and extended the famous Nyquist theory.

Physicists also note a symbiotic relationshipbetween graphene and the circuit, since they have the same temperature and heat does not move between them, but the thermal environment does work with the pull-up resistor. As a result of the separation of hot and cold electrons, the relatively slow motion of the two-dimensional material induces a current in the circuit at low frequencies.

In the future, scientists plan to find out if it is possiblestore the resulting constant current in a capacitor for later use. This goal requires miniaturizing the circuit and applying it to a silicon wafer or microcircuit. If they can fit millions of such circuits on a small chip (1x1mm), they can serve as a replacement for a low-power battery.

Recall that recently, scientists have also developed a device that generates electricity from any ambient vibration.
