Hi forest,
Here is the 'enviroment' (I mean full) text from Tesla with the Figures:  http://www.tfcbooks.com/tesla/nt_on_ac.htm#Section_2

Please feel free to quote the sentence or sentences which sound weird for you and I will try to comment how I interpret it, ok?

Thanks for the comments.

The TX coil will be fixed in the middle on a PCB which already will have the gate driver installed for later tests
(I have IXDD614DPI drivers 14A).

The 5 RX coils will also be on a PCB but slideable.

The picture above was a quick setup which had still 2 coils attached to each other via a cap, this will be removed.

bigger coil with 3,75 Watt electric input and claimed 900 Watt (EMF) output

Such an electromagnet would change the energy market ! Inductive heating and to electricity conversion !
Do you will publish your information ?

It's in Rick's video, but you have to understand it is not my process.  We have to do things step by step. Then there comes a point of general comprehension, which is like a point of no return. Everything becomes obvious at that point.

The importance of the gate driver:  The innovation by Rick is in the gate driver, because it causes a more disruptive discharge.  The disruptive discharge is  something which Tesla championed.  In this case it produces a larger magnetic field.
The difference is without the gate driver and  with the  frequency generator that has 20V PP you only get 250V PP on the transmitter coil, but 1300V with the gate driver @ 9V. So the gate driver dramatically increases the gains because of the fast rate of change.
This happens at  resonance of course, and you can see the increase on the scope shots.
The purpose of the disruptive discharge is to increase the rate of change.
The gate driver consumes about 1/4 watt at 9 volts.


At 34 minutes Rick starts to introduce the gate driver:https://www.youtube.com/watch?v=18kOGVfkoik
Look at 1:10:40 for a further gain with the big coil:  https://www.youtube.com/watch?v=18kOGVfkoik[/size]

a.king21,
Would like to ask whether the gate driver is driven with sine wave or square wave by the function generator?

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.

Hi a.king21,

Thanks for the answer. It was a blank question test whether you are willing to consider my posts at all because in the last couple of days you have avoided answers for my questions.

Well, the disruptive discharge is not correct to use here as an explanation for the increased (1300 V or higher) voltage level at resonance. 
It is okay that the output of the gate driver excites the series LC circuit with square wave, it can surely be considered as a very fast switch.
However, you (or Rick) forget to consider the teaching of the Tesla's patent "Coil for electromagnets". i.e. in plain English, in an LC circuit
the input current (having the same frequency as that of the resonant one of the LC circuit) finds no any resistance (to enter and flow) other than that of the wire resistance of the coil.  So there is no for instance the usual inductive "kick back" you find when pulsing a coil and when no resonance is involved.
But this fact would not provide a larger magnetic field (hence voltage increase) in itself, something else insures that. There is nothing fancy,  there is a normal explanation for that.
I would wait with the answer and leave to you to find it.

a.king21, I have to thank you for the further information given by #333 and #334 reply !

So this is the same information source and technical design like benfr is referring.

So now the statement "900W" magnetic field force is based by electric  " 1300 V x ?" discharge  !

Excitated surge power with short duty cycle
Okay !

Sincerely
OCWL

I completed a prototype for a receiver and the transmitter, see picture

The receiver has the 163uH coil, a 100pF trimmer cap, 4x bat46 schottky diodes as FWBR, a bidi 220uF buffer cap and
a 50 Ohm 1% inductionfree resistor (load).

The transmitter has a 163uH coil, an empty socket for a future gate driver, 2x 100pF in series (50pF) cap and is
driven now by my FG.

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

Blue is the the input voltage (5Vpp DC)
Green is the input current
purple is the voltage across the 50pF cap
Red is the math trace (blue x green = input voltage x input current)
 
The DMM is across the 50 Ohm load and shows 244mV.

So we have 25.6mW input, and the output across the receiver shows 1.2mW  (P=U²/R  =0.244²/50 = 1.2mW)

Moving the receiver closer increases its output, but effects the transmitter resonance frequency.

Will build 4 additional receivers now.

Regards Itsu

Hi itsu,

Thanks for showing the details on the measurements.
Would like to ask the DC resistance of both the transmitter and the receiver coils when you have time to check them. 

Yes, it is normal that the receiver coil detunes the transmitter coil and vice versa, especially when you will have
all the 5 receiver coils. You will need to fine tune all the trimmer caps a little whenever you change on the distances
between TX-RX coils. In fact, you would need a fine tuning possibility for the TX LC circuit but maybe with slowly
fine tuning the function generator to the slightly pulled TX LC circuit (pulled by the RX coils whenever distances
are changed), you would not need a trimmer cap there. 
Of course when fine tuning the generator for the TX circuit, the receiver coils need retuning a little again,
a mutual back and forth interaction happens and should be corrected accordingly. On the receiver side
an analog meter will nicely show the voltage maximums instead of a DMM.  I think you know all these.   8)

Hello itsu,

https://www.google.com/search?q=kanarev+pulse+power&ie=utf-8&oe=utf-8&client=firefox-b-m
Kanarev showed the problem with pulse power calculation.

Voltage pulse amplitude
Current pulse amplitude

Power pulse amplitude

Pulse duration
Pulse repitition period
Pulse frequency

Duty ratio
Duty factor Z

Average Voltage

Average Amperage

Average power

So the first question : how much real input power ? pulsed P to P = ( UxZ)x(IxZ)     = 25,6 mW ?


Sincerely

Of Snakecoils and other things

In the early days of radio, engineers and experimenters figured out fairly quickly

that if you wanted efficient transfer of power, you would need to have excellent

coupling (K approaching 1.0). Minimizing distance between air core coils by nesting

them one in the other co-axially helped to achieve a higher K while separating them reduced K.

Where multiple secondaries were needed, these were also nested co-axially to keep

the coupling factor between coils as high as possible.

Itsu has just demonstrated the effect of a low K transformer, where power transfer

is greatly reduced. Had his coils been nested coaxially, the K factor and coupling

would have improved considerably.

Somehow the idea has crept in due to the inexperience of certain "teachers" that

just adding a lot of coils separated from the primary coils will magically increase

the power transfer. This is not so.

When the words "primary" and "secondary" are substituted for "transmitter" and "receiver"

it becomes obvious what we  have is a common air core transformer with a low K factor.

and thus a large  amount of the mystique is removed.

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.

 Loads that only require milliwatts such as super bright LED's or neons only lightly

load the secondaries and serve to fool many in place of the accurate primary and

secondary power measurements needed to be done with good equipment. The cry we hear

is "see how many led's I can light on all my little coils with only one transmitting

coil" but no real measurements are performed.

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.

Regards
