I should rephrase that a bit as it was not directed towards yourself. It's just that the entirety of electromagnetic theory as practiced, is cobbled together with a number of known inaccuracies, based on outdated theories that go back to the time of the Civil war, when they didn't understand if they were measuring a transverse wave or a longitudinal wave etc. . The engineering departments seem to be missing the findings of the Physics departments. The fact that standard circuit design builds in self defeating back EMF as example. In layman's terms its a little like closing a shutter over a windmill or solar panel as the current begins to flow. Whatever. Each has to do their own homework. Gotta go.

I respect the fact that you are a patent attorney of note etc- would only briefly mention that they are not discussing "a vacuum" in the terms you are thinking of it. Don't really have time to discuss for instance 1: the difference between Maxwell's Theorems with 26 points of freedom, versus Heaviside's misinterpretations which ignore any overunity considerations...2: open loop vs closed loop systems. 3: the term " free energy' is generally a misnomer & as popularly misunderstood as many other things that people get a surface view of without taking the effort to understand & wish to reduce to their level of ignorance....ironically while we are obliviously whirling through space within a breathtakingly designed system of spheres, with lightning touching down all over the planet all the time, etc...
