Re: [Vo]:2nd Law proved not valid, ignored by West
Dave, Of course, we have known about "dark current" and photocathodes for almost 100 years, and also thermionic emissions are not new - but here is the novelty. Fu set up magnets so that the field lines were arranged to steer electrons in a way like MHD ... so that resulting polarity separated making current available "for free". No added heat is required, resulting is usable electric power from ambient. Not much power is seen, but OTOH there was zero added heat. Has that been done before? Is this scale-able to higher levels?

This has already been observed when thermal radiation is emitted by a warm body. Also, electrical energy can be captured from a resistor surrounded by a heat sink. I am not sure why the report you refer to claims to be a first. Dave -Original Message-t In the disclosed Maxwell's demon type of experiment from 2012, heat from ambient air was converted completely into electric energy, using a static magnetic field without producing any other effect. The phenomenon proves clearly that the second law of thermodynamics is not universally valid, even though the output was tiny.
