Thanks Wesley, I like Luc's approach of small steps and I like your distinction of the behavior of the gobau line and why a return path is not required. I've watched a few of your vids and have altered models accordingly so I can adjust height of top load .


I'll working with old coils and building a new circuit and I'm waaaaay less proficient than luc and have less time to dedicate. When I get stuck though I'll be coming back to your posts. I have enough room here to erect something big

video made by  non  professional but  talking about the historical facts and  one of  them is 2018 establishing
office  in Bahrain  by NewPower cooperating with  Viziv Texzon   
watch it from here:

conclusion:
despite all of the skepticism Corum  brothers  who are  the source  of  everything  around using  their business with  high rank of  former lobbyist,military, known
figures in  politics  are pushing oil industry to consider:
- what will be the future  of  oil?
-what will happened if oil industry will  be  ignoring them?
-will they   be  willing to  cooperate and put billions of their own money to be at the right side at the right time.?
There is no place  for everyone there,  as someone must be  a loser.
Chevron is already  sucked  into  it and Milford Texas  Tesla Tower ins the  result of that.
For us  Viziv  is  only training  ground.
Learning how  to  send energy from  point A to B  is mandatory to have practical  and theoretical  skills to get to the next step:
Extraction  of Energy from Schumann waveguide.

I have enough room here to erect something big 

Size is not so much important. 
The reason why Viziv is so big is:
- the  voltage  and power foreseen/ expected ·  envisioned as to be transferred  by the  tower.
- the frequency  of operation 18kHz  , Corum  Bro's  don't  yet use  CC and CCW  winding technique  to make coil smaller.,
To make tests  with  smaller coil:
- the frequency of tests  can be  as high as 54Mhz..
- the transmitter can be  typical Ham transceiver  with  typical 100W# PEP.( use it  only at 10W as you may burn the  power transistors due to impedance mismatch)
-at any of  ham bands  the Ham is allowed  to have legal tests .
-the mode of operation CW ( use it in CW at best with electronic keyer  , not continuous CW!! as you may burn the  power transistors due to impedance mismatch)
-the  structure  and first tests  can be  done from starting scratch  in 1 day.(at best using 2 people.)
-The structure can stay there and be used  many  times with alterations done later.

_{legal note: HV is dangerous   I don't take any responsibility  for anything you  do.
that note applies to all of  my posts and comments  in here and in any other pace.
If  I'm not the Ham than I must  use e.g, - the friend who has  FCC  approved license to operate at Ham frequencies.
The best advice is do nothing heee.}

Thanks Wesley for all the details.

Here are my v 2.0 secondary Tesla coils side by side with the first set I tested.
The new ones are wound on 39" inches long 4" i.d. pvc sewage pipe.
1400 turns of 22 AWG

Wesley, I have a question regarding the primary coil. Could I use 3/8 flexible copper pipe instead of Litz wire?... which is best?... does copper mass matter?

Kind regards
Luc

Yes you can and yes it  is recommended
By the way,  great  job  .

it doesn't  have to be flat  coil

I found another make and type, with similar specs and it uses 3.333 kHz measuring frequency when in the ground resistance measurement mode (page 17 in pdf file https://www.instrumart.com/assets/DGC-1000A-manual.pdf ).  It is very likely your meter also uses a some kHz test signal in ground resistance mode.

3.3kHz sound about like the frequency of my meter. Listen to the (below) video again which I purposely brought the camera mic close to the meter and you can clearly hear it. You can download this free audio spectrum analyzer http://www.techmind.org/audio/specanaly.html to find the peak frequency.

You measured 440 Ohm for one of the copper pipe groundings, does the other pipe have a similar resistance I wonder. When you have time would you check both at the same time.

Today the original grounding rod I measured with the impedance meter is 340 Ohms and the second one is 640 Ohms
