very much known video blogger forum:
The guy who created that forum  is  opposing the concept of Viziv and that is OK with me.
however  it is interesting comment  there  (link above)It explains  very low losses due to
VLF.
EEV is brilliant Engineer, however  he better keeps to that what he knows the best.
He  "attacked" FE community calling us  with names.He also made special
video expressing his opinion.

With all due respect  he also tends to  ban some individuals who have
opposite opinion.

The main difference between us is that (I believe that) he needs to make
money on any activity he  does..
I see his YouTube as very professional, but  not much beyond that .
It is just his narrow field of expertise
he is good at.

A Zenneck wave is produced at the zero of the reflection coefficient of a plane incident TM wave (at the Brewster angle of incidence) on an air-dielectric interface, whereas surface waves are produced when the TM reflection coefficient is infinite. Both the Zenneck wave and the surface wave are TM waves and are nonradiating, as they have, in general, exponentially decaying fields with distance. For the Zenneck wave, the evanescent transverse field components do not change appreciably with frequency (because the phenomenon of Brewster angle is independent of frequency), whereas for a surface wave, with an increase of the frequency the wave is more closely coupled to the surface.

At Wardenclyffe Tesla operated at frequencies from 1,000 Hz to 100 kHz.
He found the frequency range up to 30 – 35 kHz, "to be most economical."

_{Based upon an analysis of the Colorado Springs Notes and other sources [including Corum & Corum]
it appears a basic World System oscillator would develop a wave complex with an extremely low frequency (ELF)
in the 6 – 1000 Hz range [obtained with an alternator, NTAC, p. 155] plus a very low frequency (VLF) component around 25 – 35 kHz.
Tesla specified a frequency of 925 Hz for power transmission in the patents "System of Transmission of Electrical Energy"
U.S. Patent No. 645,576, dated March 20, 1900 and "Apparatus for Transmission of Electrical Energy"

Hello

Experiment Experiment.
Instead of wire connecting two tesla coils -- Distilled Water.
So i cut a 5 feet of plastic pipe in half so it formed a vessel. Filled it with distilled water and  using alligator clip connected end of coil and water .
Coils are tuned so when connected with wire you can see lit light bulb on receiving side. Power Level low so no transmission without a connection.
In my opinion this could be interesting if one can make a power transmission. Measured over 20M Ohm of resistance. Is it possible to match impedance or surface wave transmission is the only option??

Thank You   
P.S.
So far I did not succeed 

yeah why not make a mini tesla coil or use a TV lopt so it creates a plasma spray from loads of sharp spikes and put into a mesh tube to create an ion field anduse magnets to direct theions out to a collector ?

Earth Transmission Wirelessly sending power through the earth is a project funded by the National Science Federation (NSF).
The purpose of this experiment is to send power to sensors in a field an and to determine the characteristics and viability of sending power within the earth.
The principle of earth transmission is similar to the single wire wireless power transfer characteristics of a coil.
The earth completes a path between the top and bottom electrode of the system. 
Placing a current through the top electrode of the well will cause a current that will transmit into the earth and propagate across the skin layer of the earth.

This is a very similar phenomenon like seen in a Zenneck wave.

As Tesla said the goal is to charge a capacitor to the highest possible voltage and discharge it violently through the primary in the smallest time frame with no alternations or reversal.

Could you please point me to the reference where Tesla said the was discharging a capacitor through his primary without alternations or reversals?

It is no easy thing but I can tell you from experience that when you do get it right all hell breaks loose. Quite literally everything becomes a conductor in ways few would expect.

You know this from experience? What did you do to "make all hell break loose? What unexpected ways are making everything become a conductor? If you did this once, then why not do it every time? Please tell me the experimental conditions that created this effect.

Respectfully
Orion
