FAYETTEVILLE, Ark. A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current.

"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery.

The findings, titled "Fluctuation-induced current from freestanding graphene," and published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene a single layer of carbon atoms ripples and buckles in a way that holds promise for energy harvesting.

The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado's team found that at room temperature the thermal motion of graphene does in fact induce an alternating current (AC) in a circuit, an achievement thought to be impossible.

Three laws of thermodynamics

You cannot win : you can never generative more energy than you consume.
You cannot break even : you cannot generate even the same amount of energy you consume.
You cannot get out of the game : Entropy always wins....

How pathetic is it that my lone reference point for graphene is the vaccine conspiracy theory? I assumed it was a fake substance.

I see yo're a fan of The Wiz. Funny how they slipped in the laws of thermodynamics into the song

This article pings my BS meter at a 10, but I don't know enough about the physics of it to explain why. So, am I wrong to be skeptical?

Cute, been teaching this in P. Chem this since the 80's. Never seen the Wiz, will have to rent it now.

Second - Entropy. Things move in direction of disorder... not order.

I think this would apply to my point that predictable nature of the movement would become less predictable.

One of the 3 laws of thermodynamics is being broken here. I can't remember which - age issue.

There are only 3.

Again... another swipe at that...

First - Conservation of Energy. An object in motion stays in motion until an equal or greater force.

This Law would state that if you captured the energy from the atom's motion, the atom would lose momentum and thus begin to move less. It would also affirm my position above that the atom would just move away from your capturing device.

Second - Entropy. Things move in direction of disorder... not order.
