Circuit Design Claimed to Harvest Tiny But Infinite Power From Brownian Motion | NextBigFuture.com

At room temperature, micron-sized sheets of freestanding graphene are in constant motion, even in the presence of an applied bias voltage. University of Arkansas researchers collecting the displacement current using a nearby small-area metal electrode and present an Ito-Langevin model for the motion coupled to a circuit containing diodes. Numerical simulations show that the system reaches thermal equilibrium and the average rates of heat and work provided by stochastic thermodynamics tend quickly to zero. Power is dissipated by the load resistor, and its time average is exactly equal to the power supplied by the thermal bath. The exact power formula The post Circuit Design Harvests Tiny But Infinite Power From Brownian Motion first appeared on NextBigFuture.com.
