The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

Maybe not, from the layout and frequency of the system you would need a special antenna to receive anything. Probably something like a TC secondary tuned to the right frequency (a multiple of 7.83 Hz) with a ferrite core would do well.

wrote ... Many engineers and physicists have dismissed Tesla’s wireless energy transmission as unscientific, without examining the unusual characteristics and benefits of longitudinal waves – which are the z-component solutions of Maxwell’s equations.
Amusing. Perhaps the authors of this article would benefit from cracking open an electromagnetism textbook. Engineers and scientists are well aware of longitudinal wave modes. Not to mention z-component is meaningless without defining a coordinate system, although in this case they mean the direction of propagation is along the z-axis presumably.

HVDC at least proves you can use the earth as an efficient conductor, so a harmonic oscillation setup between it and the ionosphere sounds plausible enough I wouldn't rule it out out of hand ... but even if it did work, how would you ever meter the consumption?

Far too easy to steal the power ...
The story I heard years ago was that the original distribution system proposed by Tesla was wireless, but Westinghouse said 'Where do we put the meter?'....So Tesla had to invent the AC distrubution network with wires instead.

He actually invented the wireless system after the wired system. The wired system is all based on one lecture that he gave to the Institute of Engineers. After returning from Colorado Springs he got funded by J.P Morgan to create radio, but Tesla was in fact setting up his wireless system. When he approached Morgan for more money, Morgan pointed out that Marconi had transmitted radio at a fraction of the cost. Tesla fessed up and told Morgan the real reason for the tower, and that's when Morgan said "Where do I put the meter?"

Actually! That meter comment was real, That alone i think is the main reason Tesla was cut off. Without the ability for rich arrogance to stuff more and more cash into their wallets great ideas often go down the tubes. Teslas wireless power has undergone scrutiny for years, probably since he first mentioned it! His answer was always that it would improve living conditions around the entire planet. Remote areas could have access to power, islands, mountain areas, you could even use his wireless grid underwater! Any place you could have a ground point and a resonator! But hey, who wants better living conditions worldwide unless you can get filthy rich off of it... There is a book that goes over the entire patent and theory behind the whole idea. Its called "The Fantastic Inventions of Nikola Tesla". I am sure it is not the only one around.

Except, perhaps for the wrong reasons, JP Morgan was right to refuse to fund Tesla's wireless power grid, because such a system would never have worked.

I would rule it out quite easily. The Schumann resonances are constantly excited by lightning. It's pretty trivial, with the right equipment, to detect the Schumann resonances, and see that the overall Q of the earth-ionosphere cavity is very very low. You'd have better luck transmitting power with a length of wet string.
