"Tesla Describes his Efforts in Various Fields of Work" Electrical Review

As to the idea of rendering the energy of the sun available for industrial purposes, it fascinated me early but I must admit it was only long after I discovered the rotating magnetic field that it took a firm hold upon my mind. In assailing the problem I found two possible ways of solving it. Either power was to be developed on the spot by converting the energy of the sun's radiations or the energy of vast reservoirs was to be transmitted economically to any distance. Though there were other possible sources of economical power, only the two solutions mentioned offer the ideal feature of power being obtained without any consumption of material. After long thought I finally arrived at two solutions, but on the first of these, namely, that referring to the development of power in any locality from the sun's radiations, I can not dwell at present. The system of power transmission without wires, in the form in which I have described it recently, originated in this manner. Starting from two facts that the earth was a
conductor insulated in space, and that a body cannot be charged without causing an equivalent displacement of electricity in the earth, I undertook to construct a machine suited for creating as large a displacement as possible of the earth's electricity."

The mistake is assumption he thought about solar panels.

  If that video at the end is from Old Scientist, well, he could barely light a florescent bulb, from his wireless transfer video while using big bike wheel sized coils, and a spark gap set up.
   His test on wireless transfer from one coil to the receiving coil was about 8 inches distance, and barely and unevenly lighting a florescent tube.  Not too impressive, nor the video that you posted a link to. Jacking the voltage up by a factor of 3, but unable to show it doing anything. Oh, the capacitor stores it. Like for a rainy day?
   The device from YT video that you posted previously from jb-n107lab, was shown self running, and there is a recent video made about 4 months ago. Interesting... and supposed to be self running, as shown in his previous video.  While no other self runners are being shown, at least that I'm aware of.

Don't be fooled by the lack of wasted radiation into space the focus is along the tube with bifilar wound L1 but that wasn't the focus there it was the waveform in
the blue box generated by the 'spark gap' was producing a 'SNAP' effect like a 'pistol shrimp'! he shows a threefold back for 1 in with that setup. Watch it again and observe every detail.  see graph on the bottom of the previous page.

Related to Goubau's article, it should be noted that the propagation depends strongly on the nature of the surface. Long and medium radio waves propagate very well over the sea, which is a much better conductor than the land. Spain is about 400 km from my position with only the Atlantic Ocean in between. Spanish MW radio stations are perfectly received here with strong signals, even during the day, while stations 100 km away in the countryside are poorly heard.
Anyway, I am not able to extract here the slightest milliwatt from the hundreds of KW sent from Spain. Radiant energy is useful only if the energy receiver is coupled to the transmitter, which involves interaction between transmitter and receiver, otherwise the energy is not directed towards the receiver, and it is radiated even if no load is connected, which is a total waste.

Any DX er will tell you the signal is bounced off the ionosphere relating to its wavelength a bit like Luxembourg in the 60s pop culture but is that true? but how much POWER can you really capture from RF smog? When i was a school kid there was this old guy in phoneadeck's R&D he was an amateur radio enthusiast he had some homebrew radio with a triode and an output pentode 10 watts he could put a 100watt bulb in the output load an output the thing to over full brightness blackening the inside coating with a static charge on the outside. Explain that.

Zenneck waves/ surface waves - do not radiate. They move along the interface. They are invisible in perpendicular  plane ( vertically) above and below the interface  (earth surface).
...

The waves described in Goubau's article of which you provided the link propagate along the surface, and consist of the magnetic component that is along the surface, and also the electrical component that is in a vertical plane, perpendicular to the surface on which the wave propagates, but is vanishing a few wavelengths above. Although it propagates on the surface, the wave occupies a volume above the surface (of at least a half-wave height).

Any wave that propagates by carrying energy, radiates by definition. The waves in Goubau's paper radiate. If they didn't radiate, we wouldn't need the hundreds of KW that power AM radio transmitters. It is the fact that the wave carries energy from the source that makes us call it a "radiant wave".

Radiant waves are a solution to remote energy transmission only if they are focused between transmitter and receiver. This does not depend on whether the wave is a Zenneck wave or not, but on the ability of the wave to maintain its energy volume when it moves. When the Zenneck wave is an electromagnetic wave transmitted from a radiant pylon antenna, it travels in all directions 360° around the pylon, while remaining along land or sea surfaces.

If you want a wave that doesn't spread, you don't need Zenneck waves especially, but solitons.
The problem is that we don't know yet how to produce this type of wave in free space (even on a surface).
