A The team of physicists at the University of Arkansas has successfully developed a graphene circuit capable of producing unlimited clean energy. The new system works by capturing the thermal movement of graphene and turning it into an electric current.

“A graphene-based energy harvesting circuit could be incorporated into a chip to provide clean, unlimited, low-voltage power for small devices or sensors,” said Paul Thibado, professor of physics and lead researcher on the discovery.
However, the research doesn’t come without its fair share of controversy. This is because it goes directly against the work of famous people physicist Richard Feynman who assumed that the thermal motion of atoms, known as Brownian motion, could not be worked on.
The diodes were placed in opposition so that the current could flow in both directions. This has produced a DC current that does the work on a load resistor and increases the amount of power delivered.
“We also found that the on-off switch-like behavior of the diodes actually amplifies the power output, rather than reducing it, as previously thought,” said Thibado. “The rate of change in resistance provided by the diodes adds another factor to the power.”
To prove their theory, the team had to use a new field of physics. “To demonstrate this empowerment, we drew inspiration from the emerging field of stochastic thermodynamics and extended Nyquist’s celebrated nearly 100-year-old theory,” said co-author Pradeep Kumar, associate professor of physics.
The team is now trying to determine whether direct current can be stored in a capacitor for later use. The research is published in the journal Physical review E.
