"Graphene-based Nonlinear Circuit Revolutionizes Clean Power Harvesting"
Originally Published 2 years ago — by Phys.org

Scientists have designed a novel nonlinear circuit that harnesses clean power using graphene. The study demonstrates that thermal fluctuations of freestanding graphene, when connected to a circuit with diodes having nonlinear resistance and storage capacitors, can produce useful work by charging the storage capacitors. The researchers found that the system satisfies the laws of thermodynamics and that larger storage capacitors yield more stored charge. This breakthrough paves the way for the development of graphene energy harvesters that can gather energy from the heat of the earth and store it for later use, offering a new source of power that does not require a temperature gradient.
