Fermi energy contribute to the field in the inductor

AI Thread Summary
The discussion centers on a theoretical refrigerator design utilizing copper walls and a silicon chip at its core, functioning as an L-C oscillating circuit. As the chip heats up, electrons transition into the conduction band, contributing to an inductor's field. The inquiry focuses on the fate of energy once the inductor collapses and recharges the chip, and whether this mechanism effectively prevents thermal energy from entering the refrigerator. The conversation also touches on the Peltier and Seebeck effects, clarifying that while the Peltier effect involves dissimilar semiconductors, the proposed concept aims to explore the use of silicon or germanium in this context.

Ok, so here's the basic idea. You have a refrigerator, with four walls each 6ft x 2ft x 4in. The walls are made out of copper(high thermal conductivity), with a silicon chip at the center. This chip is connected to an inductor and is essentially a L-C oscillating circuit. As the chip heats up, electrons pass into the conduction band as per Fermi-Dirac. These pass into the inductor. Once all the electrons with the Fermi energy contribute to the field in the inductor, it collapses and recharges the chip. My question is, what happens to the energy at this point and will this keep thermal energy out of the refrigerator.

I'm familiar with Peltier, but that isn't related to semiconductors. Peltier uses junctions of copper and bismuth, I'm thinking of something that uses silicon or germanium.
 
Errm, Peltier effect works just fine between two dissimilar semiconductors.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
