I do believe that I am looking at the Ammann brothers' circuit ...


I removed the battery, which powers the sine wave generator, since it is not part of the efficiency of this circuit. The battery has merely to do with the efficiency of the sine wave generator which is a separate issue, because it doesn't matter from where this circuit gets its frequency input just so long as it is a single frequency of a pure sine wave embodied by a miniscule voltage vibrating at something less than 80k Hz.

Personally, I'm willing to suspect that the "handyman" who came to the home of C. Earl Ammann to do some remodeling prior to the Ammann demonstration was sent there to suggest that he go public with his invention. This is what got C. Earl into trouble, but it was a way to "flush him out" of privacy. There were no laws at that time to penalize anyone for disrupting radio communication or for "stealing from the grid" as he was later charged with. Only when he stepped onto federal territory (of Washington, D.C.) was he arrested and charged. So, the jurisdiction of any level of government beneath the level of federal authority was severely limited. And the FCC had not yet come into existence to "own" the airwaves. That had to wait for another 13 years after the Ammann demonstration of 1921.
