Did I get that correct? I may not be older than quantum physics, but I am older than the first high school text books that covered it.

Luckily for me, string theory and gravitrons have never affected my work. The math models that cover power and control fit the real world very well. And I understand those models fairly well.

You posted E=mc2 but if you want to get down to the particulars, we need the full equation for the mass conversion that also has momentum: m = sqrt(E2/c4 - p2/c2)
There is no need for me to provide the equation for the energy flow outside the ideal conductor because you already have it: the equation for the Poynting Vector, which was the basis for that whole line of discussion. In an ideal conductor, the axially-directed electric field, which is external to the conductor surface, crossed with the magnetic field encircling the conductor gives the energy vector flowing towards the load.
