So does the scope calculate !

Hi forest,

We are off topic here, so I apologize from all the members here.

1) I agree that Tesla wanted to disturb the 'electrical equilibrium' near and or in the vicinity of his antenna but I do not know whether he expected to tap the external energy higher than the amount he invested as the input for disturbing. What you quoted from him in this 1st paragraph, it refers already to his wireless energy transfer tests. I think once he mentioned efficiency obtainable in energy transfer through the Earth as 94%-95% or around that.   


2) Well, in the text you quote from him, he refers back to his single wire energy transfer tests where he found that high currents went through the wire i.e. it was capable to transfer high current. Note that in case of the single wire transfer, the remote end of this single wire must have been connected to the receiver means while the 2nd wire was the Earth. And his next step was to get rid of the single wire too, hence the wireless energy transfer test came. And doing the wireless tests he expected to transfer also high currents via the antenna wire, the top of which had "all short of devices [attached] to constitute the capacity" and even though all this elevated structure was insulated, the energy transfer took place -- this is how I understand here his text. On elevated structure I mean a certain lenght of wire with capacitive end loading, driven from an AC generator and the other terminal of the generator was grounded. These tests was leading him eventually to the magnifying transmitter. He wanted to disturb the Earth natural resonant frequency which is around 11.6 Hz (cannot recall the decimal exactly but not the Schumann resonance!) and then the oscillating Earth could feed receivers built on many points on the surface.

1. "  My idea at that time was that I would disturb the electrical equilibrium in the nearby portions of the earth, and the equilibrium being disturbed, this could then be utilized to bring into operation in any way some instrument" 

My understanding : my instrument should be able to disturb local Earth potential and make difference which can be utilized (power some other instruments) - the idea is to tap external energy
2. "I had already proved in my lecture at Columbia College that I could transmit energy through one wire; therefore, I was prepared to find that a current of considerable strength could be passed through this wire here [connecting the alternator to the elevated capacitor], although it was insulated. "
My understanding: the first part is utterly misleading (everybody thought he tried to move current inside the single wire ) but he is ONLY explaining that he can move charge in environment around because Earth is like single wire )of immense diameter) - the second part mach the previous text : "although it was insulated" - that part makes no sense if the charge is inside wire or insulated is elevated capacitor - because that is natural way to insulate electrical circuit to avoid looses.  So why he mentioned this ? Because he was about to move charges from the ground to the elevated capacitance or rather to the antenna. Energy from outside flow around the circuit - that's the only explanation I could find.
Now maybe I'm wrong, Tesla notes are very subtle and the real meaning seems deep hidden below the simple explanation, but after reading a lot some parts just start to do not match this simple explanation.

This is what my Spectrum Analyzer picks up on harmonics with a probe near by the TX coil.
First with the square wave signal,
second with a sine wave signal:

....
In an air core transformer with multiple secondaries widely distanced from the
primary you cannot capture more power in the secondaries than is being input
regardless of the certainty of those who teach this. Because of the separation distance and low K,
much of the primary power will not be useful to the
secondaries, and this is normally termed leakage inductance by engineers.
...
Also being espoused by the new "teachers" is that you need to resonate the secondaries to get the voltage to
increase. You may do this, but when you then place on the secondaries a useful
load, you wind up collapsing the high voltage that was created in resonance, killing
the Q of the resonant tank. The high resonance voltage is greatly reduced due to the
fact that power is delivered out of the resonant system at the same rate it is being
input, so there is little to nothing left for the resonant system to work with to
store energy and build a high voltage.
....
Thank you Itsu, for your actual power measurement  clearly demonstrates that the separation distance
that creates  poor coupling (low K) greatly reduces power transfer in an ordinary air core transformer,
regardless of the resonant tuning of such. BTW, this fairly accurately agrees with simulations of the same.

Hi Vortex1,

Thanks for your post, I also agree with all you wrote.  I quoted only the most revelant sentences, to see them again. 

Anybody is free to prove COP > 1 performance in this setup by showing correct measurements if he does not agree with the thoughts expressed in Vortex1's text.

It seems there was a small typo error in Itsu's post #341

FG is set to resonance (1.578Khz) square wave 50% duty cycle, pulsed DC (like a gate driver would) and the screenshot shows:

Should this have read 1.578 MHz? As the later spectrum analyzer shots seem to verify it is 1.583MHz approximately, not kHz.

Edit: This has been addressed in post #349, which I missed.

These variable coupling transformers are "loosely related" to "loose couplers"

For more information on loose coupler transformers see here:

http://www.sparkmuseum.com/COUPLERS.HTM

http://peeblesoriginals.com/ppp/loosecoupler-radio.php

Coupling in these air core transformers can be high (tight) when the coils are nested and low (loose) when they are separated, hence the name.

Thanks to those that have approved my earlier "long winded" dissertation.

May I go out on a strong limb and predict that more power will not be available on multiple resonant secondaries than is input to the primary.

Prove this is wrong with accurate measurement by those who believe otherwise.
