'bullshit'

#5Naive question, wouldn't this (converting Brownian motion into electricity) violate the 2nd law of thermodynamics?
(edit, this is explicitly addressed further in the article: That's an important distinction, said Thibado, because a temperature difference between the graphene and circuit, in a circuit producing power, would contradict the second law of thermodynamics. "This means that the second law of thermodynamics is not violated, nor is there any need to argue that 'Maxwell's Demon' is separating hot and cold electrons," Thibado said.)

#6It’s more like “limitless power from heat transferred into graphene from an external power source”. So it’s a special type of a thermo electric generator basically.

I think it's going to be able to essentially deliver a very small current virtually indefinitely.

If I'm understanding the article correctly, a very tiny piece of graphene can pick up a very tiny amount of energy from the random jiggles at the atomic scale.
Presumably, those jiggles are always going to be there, unless somehow earth becomes a cold, dead place.
So imagine the solar panel on your calculator didn't need light, just a temperature above absolute zero.

That's how I understand it as well. It harvest the brownian motion of atoms in graphene.
I definitely don't know enough about this subject to judge the plausibility of the claim but "graphene" and "limitless power" in the same headline does trigger a few red flags.

Thank you; awful title.
