Since 2002, at least two kinds of laboratory-testable, solid-state Maxwell demons have been proposed that utilize the electric field energy of an open-gap n-p junction and that seem to challenge the validity of the Second Law of Thermodynamics. In the present paper we present some arguments against the alleged functioning of such devices. 

Critique of the Paper "A Note on Solid-State Maxwell Demon" by Germano D’Abramo

Since Dr. Sheehan has published his discovery of the solid-state Maxwell demon (SSMD) many people have attacked the concept, simply because it violates the 2nd law of thermodynamics, which they

The Demon in a Vacuum Tube

It is argued that if the demon and the system on which it operates without dissipation of external energy are made of atoms and molecules in thermal equilibrium, then the unavoidable reason why the demon cannot successfully operate resides in the ubiquity of thermal fluctuations and friction.

"Closed-loop" analysis of a thermo-charged capacitor

In this Letter, an explicit application of conservation of energy and zero net work principle around a closed path ("closed-loop" analysis) is carried out on a thermo-charged capacitor at equilibrium

The photoelectric effect induced by blackbody radiation could be a mechanism to harvest ambient thermal energy at a uniform temperature. Here, I describe (without going too much into mathematical
