I recently had a message from tac22 asking for my comments on Barbat's patent. Here is my first response.
Having just now browsed through that thread I can not see me adding anything useful, other than to note that the subject matter is not a granted patent, it is a patent application. Poynt made the comment that it appears to be based on theory, and that Barbat may not actually have something working. In view of the 13 years that have passed since that application was made, there is no sign of a patent being granted, and Barbat has not hit the headlines with a demonstration of his system, I think it likely that his low mass electron theory is flawed. In particular I would comment that (a) near-field magnetic coupling is not a photonic effect, you can't use classical photons as the carrier, (b) the time derivative of magnetic vector potential is the driving field on the electrons in the receiving coil which create force by rate-of-change of (hidden or EM) momentum qA, not classical momentum mv. Although conduction electron mobility will determine the resultant electron velocity of any induced current, that value of current is independent of mobility but is determined by the load on the receiving coil. A superconducting coil (highly mobile electron Cooper pairs) would produce the same load current (small number at high velocity) as a normal conductor (large number at low velocity).
On further consideration I realize that my comments relate to classical transformer induction where the induction comes only from a time-changing A field. There is much controversy over another form of induction where the electron is moving through a non-uniform A field and effectively "sees" the A field change with time because of that movement. In that case the induction relates to the electron velocity. Barbat's coupled coils are not coaxial as would be the case for transformer induction, so his receiver coil are within a time-changing circular A field that reduces in magnitude with distance from the primary coil's axis. The A field along the secondary coil conductor is not uniform. Hence his coil obtains classical transformer induction related to the time-changing flux through the coil, then there could be additional induction along the conductor given by the convective derivative (v.del)A. Electron mobility would contribute to that additional induction, so Barbat's ideas could bear fruit if that additional induction could be made to enhance the classical transformer induction. IMO just coating the wire uniformly with semiconductor material will not work as I think that additional induction would be zero around each turn. But having each turn only partially coated could create the wanted effect. This would require coating as indicated in the attached image.
The presence of an electric field can draw conduction electrons to the surface, and IMO those surface electrons will have greater mobility hence will travel faster than those within the bulk material. Such a two-channel form of electron flow is already recognized. So here is another means of obtaining greater drift velocity that could perhaps help enhance the semiconductor coating effect. It requires an insulating coating over the semiconductor material and conductive electrode coating over that, with the electrode held at high positive voltage DC. Also to help eliminate the slower conduction channel skin effect could be employed.
