Graphene has long been heralded as an amazing new material that can change entire industries and revolutionize the economy. Notably this has yet to happen. Yet.
At the University of Arkansas a team of physicists found a way to use graphene to generate limitless power based on the movement of atoms. Since a graphene layer is only one atom thick the thermal changes from the Earth can move the atoms ever so slightly, so as long as the Earth generates heat this graphene sheet made the team can generate minuscule amounts of energy.
We’re finally getting to see some cool theories about graphene get turned into real applications.
The team used a relatively new field of physics to prove the diodes increased the circuit’s power. “In proving this power enhancement, we drew from the emergent field of stochastic thermodynamics and extended the nearly century-old, celebrated theory of Nyquist,” said coauthor Pradeep Kumar, associate professor of physics and coauthor.
According to Kumar, the graphene and circuit share a symbiotic relationship. Though the thermal environment is performing work on the load resistor, the graphene and circuit are at the same temperature and heat does not flow between the two.
