>Knowing this, Thibado’s group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide separate paths through the circuit, producing a pulsing DC current that performs work on a load resistor.
Always a bit hmmm when I see something simple like a rectifier spun out in a way that eludes that they invented some revolutionary new circuit.
- NavinF 5y agoYeah this is hella sketchy. >We also found that the on-off, switch-like behavior of the diodes actually amplifies the power delivered, rather than reducing it, as previously thought Wat. Why is this crap on the front page?
- danboarder 5y agoThe journal paper is linked in the article if you want to read it. For low-voltage devices it seems reasonable to me. Fluctuation-induced current from freestanding graphene https://journals.aps.org/pre/abstract/10.1103/PhysRevE.102.042101 https://journals.aps.org/pre/abstract/10.1103/PhysRevE.102.0...
- jbay808 5y agoUnfortunately I don't have an institutional login, or else I would be able to comment better. :( But it sounds to me from the abstract like the result is not significantly different from the thermal noise voltage on a resistor? I don't expect that they would be able to extract any work from the system, unless there is a temperature difference somewhere.
