From what i saw in the patents for this the ionosphere and such was not mentioned. The principles were very plausible.
More or less, using a large tesla coil to create a charge in the air over a wide area (towers he called them) and antennas
on devices that would plan on using that charge. Like lighting a fluorescent bulb near a tesla coil. The "plan" was to have
enough "towers" to overlap enough area that it would all be covered. The rest of the things that have been mentioned here
i believe i saw involved with a different patent. You may have seen Teslas drawing of the earth with the hand pump sticking out
of it. Heres a quote from the book i have, it is written by Tesla in reference to oscillatory currents in the earth. This is directed at
how to recover it according to the text and it actually shoots the idea down. "Elecrtomagnetic hertz waves radiated horizontally
from a vertical conductor, slightly affected by conducting earth surface energy unrecoverable." I think many people are confused
because he had 3 different explanations, one being theory, one analogy, and one being realization. His realization is the system
i have been talking about. The theory and analogy are the ones that begin to sound like a pseudoscience manual.
