They develop a graphene circuit capable of producing unlimited energy


Physicists have managed to build a circuit that generates clean and unlimited energy from graphene, and thus they explain its operation. Researchers have managed to develop a kind of graphene circuit whose main feature is to be able to produce clean and unlimited energy by directly transforming the thermal movement of graphene into an electric current. Although we know many uses that graphene can be given, the latest advance in this regard has been made by a team of physicists from the University of Arkansas who have managed to create a kind of graphene circuit that could end up producing clean and unlimited energy. The researchers explain that this new system works by capturing the thermal movement of graphene and then transforming it into an electrical current: “a graphene-based energy harvesting circuit could be incorporated into a chip to provide clean, unlimited and low-voltage energy for small devices. or sensors, “said the professor of physics and principal investigator of the discovery, Paul Thibado. However, the discovery has had certain controversies since previously the work of physicist Richard Feynman assumed that it was not possible to work with the thermal movement of atoms, known as Brownian movement. In any case, this research has achieved something that was thought to be impossible and that is that at room temperature the thermal movement of graphene induces an alternating current. For this they built a circuit with two diodes instead of just one, and thus they were able to convert alternating current into direct current. To understand how it works, they explain that the diodes were placed in opposition so that current could flow in both directions. This caused a direct current that works on a load resistor and increases the amount of energy. Paul Thibado adds that “we also found that the on-off (switch-like) behavior of the diodes actually amplifies the delivered power rather than reducing it. In this way, the rate of change in the resistance provided by the diodes adds an additional factor to said power ”. The team adds that to prove their theory they had to make use of a new field of physics and for this “we drew on the emerging field of stochastic thermodynamics and expanded the Nyquist theory, which is almost a century old.”
