This is a quote and you may disregard this article / publication because its perfect example how confused people are about
Tesla's Wireless Power Transmission System.

"Tesla often refers to energy being carried by the currents rather than by Hertian waves. For example, he writes

    "From my circuit you can get either electromagnetic waves, 90 percent of electromagnetic waves if you like, and 10 percent in the current energy that passes through the earth. Or, you can reverse the process and get 10 percent of the energy in electromagnetic waves and 90 percent in energy of the current that passes through the earth."

Straight away we see a problem with this. He is talking about a situation in which the reactive component of the field is to be much larger than the real components, in other words the intended destination is within the near field of the source (within say a half-wavelength to achieve the proportions suggested), or else both source and absorber are contained within a low-loss (high-Q) cavity. He is expecting the earth currents associated with the reactive near field to convey energy to his receivers independently of the EM field."

So the funny part is that he explains the process of a lanching a surface wave but still disregards its existence or possibility of its utilization.

The tesla coil can operate in two modes:
- voltage (V)
- current (A)

for V the effect is high HV
and for A high A.

This is not strange, but has anyone done such an experience and knows how to do it? I did such tests and I can say that Kapanadze could use the Tesla coil in mode A.

Hello Stivep and other forum members,


I am sorry to have to step in to clear up some misunderstanding.  If my memory serves me well, the main authors of this paper have already left to other countries a long time ago. I don't think this work has anything to do with Guangdong[size=78%].[/size]


I don't visit this forum very often but feel free to discuss, ask questions and share your knowledge with others.

Title:
Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760


From  part  #1  we have learned   that
-earth as    multilayered part of interface  is suggested.
-that is  in line  with Marconi's early experiments,
-the paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves.
-we could also look at  picture  representing multilayered  interface
-  we  had the first look at wave behavior while  "loading" into  interface

From  part  #2  we have learned:
- the  differences  between  regular EM wave known also as Space wave and Surface wave.
- the 4 layer suggested   ground  as one of parts of interface Air/Earth
- the wave  in  the  interface  must  be  in TM  mode

From  part  #3  we have learned:
-  that  the thickness of both layers  of the  interface is expected  to be 1/4 of  the  wavelength Y

From  part  #4  we have learned:
Basic schematic   of  Avramenko fork and  voltage multiplier   that can be used at any frequency
in association with Goubau line or any other type of interface.

From  part  #5  we have learned:
SIMULATED AND MEASURED RESULTS OF BASIC WPT (Wireless Power Transmission)CONFIGURATION
We can see from Fig.3b Fig.3c impressive performance   of TM in the interface.
=======================================================-this above is another confirmation of expected performance over the regular  EM wave
.-this above is another confirmation of expected performance TM  in the interface at low frequencies.
-this above is another confirmation of fact that this wave is not  present in Far Field 
_{The exact  statement  saying  it  is int the article I just must have time to find it}

<sub>I went into the article.
I search who is Paul Nicholson  the guy  is mystery  to me.
The REAL Science of non-Hertzian waves, by Paul Nicholson  no  original  link  to article was found

I happened to read the  reprint few years  ago  but it was not deep  study.
End of story is that  Article was likely published  in 2002.  the missing  are  the drawings he  referees  too.That is why his article-  reprint is somehow unclear.
The guy  had no idea  about  surface  wave and interface  as it was  at that time in  its infant  stage.
Definitely he was/ is educated  guy with nice English skills. 
He got few things  right and article is worth  reading.
Waveguide and lightning  is nicely explained,  however  again  his limitation is his approach based on lack of novelty of surface  wave science.
So my plan was to  contact him  or visit him  with some  suggestions.</sub>   

Along my search  I  got  few helpful links:
- http://www.tfcbooks.com/mainpage/links2.htm
- https://www.backyardastronomy.net/natural-radio-receiver/

"This last link  says thank you to  Paul Nicholson"

who  is  he? ??

VLF receiver is nothing more than an audio amplifier attached to an antenna.

One of the most popular uses for a VLF receiver is for listening to lightning strikes from around the world,
and the interesting effects that this activity has on our atmosphere.

lightning strike is not a narrow band event as is say a military VLF transmitter like NAA in Cutler Maine at 24KHz.
These types of wide band signals are characteristic of natural EMF activity from Earth

The article  includes schematic and waterfall of Rx.
-https://physics.stackexchange.com/questions/132576/why-is-lightning-referred-to-as-high-frequency-source
Lightning strike 

The negative flash/stroke is found to have 200KA  of current with a voltage close to 300KV (cloud to ground).
According to wikipedia, average duration of a lightning is 30μs. If we take a gaussian current splash with σ=30μs,
its spectrum will be a gaussian with σk≈33kHz.

-https://en.wikipedia.org/wiki/Schumann_resonances

Lightning discharges are considered to be the primary natural source of Schumann resonance excitation;
lightning channels behave like huge antennas that radiate electromagnetic energy at frequencies below about 100 kHz.

-https://www.qsl.net/dl4yhf/spectra1.html easy way  to receive ULF .

Especially interesting  is this link:
http://onlinelibrary.wiley.com/doi/10.1029/2005GL023028/full
Detection of thirteen resonances of radio waves from particularly intense lightning discharges
So  we know from all of links  above  that lightning is  responsible(mainly) for  Schumann   resonances and
lightning by itself is  the source of its  own  resonances  and its harmonics separately.

With that we may ask what  happen if EM wave at right tilt angle and polarization hits the earth?
Will  it land  in the interface?
Can we help EM wave to do what we what it to do  by Kapanadze process of activation?
https://youtu.be/XOTLfnMOSqQ?t=993

Lightning strikes reach the ground on Earth as much as 8 million times per day or 100 times per second,
according to the National Severe Storms Laboratory.

and we know that we need   50/60Hz per second for our electricity in our outlet.
Random amount of EM  waves  per second  produced by  lightning  with right  properties  to land in the  interface
can be  calculated.
Than this energy can be  received stored in capacitor and rectified.
The only  why we  use  AC is that is convenient but DC is used by most if not  all of  our  portable devices  also  by choice of convinience
