I don't think Tesla personally drew that image, but it's from an article which he wrote.

By working the pump faster, shorter waves will be produced which, on reaching the opposite end of the bag, may be reflected and give rise to stationary nodes and loops, but in any case, the fluid being incompressible, its enclosure perfectly elastic, and the frequency of oscillations not very high, the energy will be economically transmitted and very little power consumed so long as no work is done in the receivers. This is a crude but correct representation of my wireless system in which, however, I resort to various refinements. Thus, for instance, the pump is made part of a resonant system of great inertia, enormously magnifying the force of the imprest impulses. The receiving devices are similarly conditioned and in this manner the amount of energy collected in them vastly increased.

The Hertz wave system is in many respects the very opposite of this. To explain it by analogy, the piston of the pump is assumed to vibrate to and fro at a terrific rate and the orifice thru which the fluid passes in and out of the cylinder is reduced to a small hole. There is scarcely any movement of the fluid and almost the whole work performed results in the production of radiant heat, of which an infinitesimal part is recovered in a remote locality. However incredible, it is true that the minds of some of the ablest experts have been from the beginning, and still are, obsessed by this monstrous idea, and so it comes that the true wireless art, to which I laid the foundation in 1893, has been retarded in its development for twenty years.

This is also why Meyl's coils work "inside shielding" as he calls it, but that's simply because the shielding is totally irrelevant and it's not doing anything, the energy isn't even trying to go that way. Like wearing sunscreen at night.

Basically it shows a 3rd coil at the transmitter site with a discharge at the top terminal of the transmitter in to it like a giant spark gap. He's using it to try to maximise the activity on the ground terminal/in the ground. That 3rd coil isn't relevant to the basic working principle or theory, it's just to illustrate a certain possible configuration when looking for methods to improve upon the basic effect, because as he writes he had funding issues so had to come up with ideas to somehow get the lower frequencies he wanted without it being massive and costing millions.

Agreed.

It's not that they "can't", they must do with the way he's using them. But that's only half the story. He's reflecting energy back and froth between the two terminals on the top of each coil via the coils, essentially. The transmitter is supposed to work like a 1/4 wave resonator should do independently, and that's it. He should be using some sort of ground plane, and the ground plane should be big enough that connecting the receiver doesn't have any effect on the (tuning of the) transmitter at all. Then the receiver works like an independent 1/4 wave resonator from the oscillations coming in to it via the earth/ground plane connection. The properties of the earth/ground plane should be so big that 1/4 wave resonance and tuning of each individual coil is maintained and nothing becomes two separated halves of one, or some harmonic frequency or such.

It's like you're jumping up and down in a swimming pool, and you're causing waves which propagate along the length of the pool, reflect off the far end and come back to you. Then someone drops a rubber duck into the water at the far end of the pool. The rubber duck starts to move up and down on the waves that you created on the other end. The duck isn't a requirement of a waving pool, it's just oscillating in unison with the waves you create. So in this way it's easy to see how a SINGLE TERMINAL/single wire transmission system works, why any coil can be "shielded" with a Faraday cage or isolated "in space" as long as it's connected (or coupled) to the earth so the oscillations can enter, and why Tesla used a hydraulic hand pump analogy, because it describes perfectly what's happening. There's no need for any of Meyl's theories on it, coupling through the air doesn't even enter one's mind because it's clear that's not what's happening.

I don't know, there's a lot to be experimented with in that area. It's a lot more problematic than the stuff that's above ground because there's no easy way to put a lot of metal underground. What I can say is when using two diodes as an AV plug, an LED can be lit from lightly touching the "input" wire on the earth near the earth terminal of the transmitter, and the power diminishes with distance. When using a receiver coil, the received power can be varied through adjusting the depth of a copper pipe that's being used as the receiver ground terminal. And the same applies when holding a bulb in the bucket of soil. Depth is very important and the power varies significantly even if the distance remains the same.

As for Meyl, in one breath he says the energy is going from one coil to another through the wire, and then he puts a metal box in between them and proclaims "the energy can't be shielded". Well no, he just said so himself, the energy is going through the wire. Doesn't take a genius to then figure out why "it can't be shielded" with a piece of metal between them He contradicts himself right there and apparently doesn't even notice, or at least doesn't remind everyone of the importance of the wire in that situation. He's promoting the space between the coils as having significance, when it doesn't. It's all about the wire which he forgot about in the space of 30 seconds.

He also seems oblivious to the effect that putting his hand near the capacitance terminal of the coil would have on the tuning. He calls putting his hand near it "shielding" because the output of the LED diminishes when he puts his hand there. I call it "detuning", because that's exactly what it is. My coil does it when I walk within 2 metres. I can also stand between the transmitter and receiver and nothing happens at all, because I'm not close enough to affect the tuning of either one, and the energy is going through the wire that I have connecting them, so my standing there doesn't make any difference. Same experiment, different results - because I'm aware that holding my hand 10cm away from the coil is obviously going to have an effect, as are many others who have ever built a Tesla coil. So why someone as intelligent as Meyl doesn't realise or acknowledge this basic fact is anyone's guess. What's the reason for claiming that he's shielding the transmission?

He just seems to have this idea that the air/space plays a role, so he's coming up with explanations that fit inside that even at the cost of being full of easily identifiable contradictions. Maybe he's correct within a certain context, but as I've said before, if Meyl wants to describe what Meyl does, then good for him. But if Meyl is describing what Tesla did, then he's totally wrong and he's spreading false information.

Where was that written? It might depend on context but usually it just means a normal inductor/coil, or maybe one with relatively high inductance.

It's basically just high frequency AC. The difference is this isn't about energising gas in an RF field, this is passing current through a filament and causing it to heat up. The receiverless works because the earth becomes "energised", like the waves in the swimming pool above. If you connect certain loads that don't need tuning then energy will flow through it. That's illustrated by the diagram talking about plugging bulbs directly into the earth, and the same experiment which you probably know about that Tesla is said to have done. It certainly works with a bucket of soil, and the soil "radiates" enough energy to light a neon bulb and fluorescents. I would expect the exact same effect happens with the earth itself when more power is used because I've been able to light LEDs and hear my own transmission through a crystal earpiece in my garden.

Probably the most curious thing of all is why should the energy want to flow from "ground" to an elevated piece of metal, or human body, and do work in the process, when it seems so much easier to just not do any of it.

Can you see what's happening at 7:00 in my video clearly enough? The energy is going from the ground end of the coil to a 20cm length of 6mm diameter stainless steel rod pushed in the plastic bucket of soil. A stainless steel bowl is placed next to the bucket and is connected to one terminal of a bulb, and the other terminal is connected to a larger stainless steel bowl. Energy flows from the soil, couples with the small bowl, for some reason wants to also flow to the bigger bowl, so much so that it goes through the resistance of the filament causing it to heat up and produce light. Adding bigger pieces of metal on the far end of the filament will cause even more energy to flow through and light even brighter. Meanwhile, the bucket of soil itself is resting on a concrete floor at ground level and is most likely coupling to the earth also, so not optimal conditions for doing an isolated experiment.
