Hello romero and all

OK i am almost ready for a first test

I did the coil exactly as Romero  that is  84 turns  plus 22 turns plus 6 big turns.

the coil 1 and 2 have the same stranded wire (blue) and  for the big coil (green and yellow) there is 7 strand of plain copper,

the center is made with 4 stranded copper and something torsaded for connection to one ground line, plus the main blue wire connection to the spark gap.

the mot is rated 700 watts. I will use it directly (without the cap and diode for a first test. What do you think ? Or can i use the MO cap  (0.95 micro farad and 2100 volts) and HV diode.?

I will ground it with 2 ground line conducting to 2 galvanised steel bar going 1 meter deep in the ground. and separated about 15 meter.   I intend to use a wire with 3 time 1.5 mm2 bounded ,for the ground lines .

I intend to begin with a halogen 500 watts what do you think ?

If it works, i will post the pictures of the construction of the coil step by step.

good luck at all

Laurent

Stop pussy footing around and plug it in!  Just make sure its outdoors and well fused. On AC you wont be able to run it for more then 90 seconds anyhow.

I am wondering about the quality of the actual earth surrounding the copper pipes.
I have a little spot with trees next to my house, i have been digging 2 holes 60 cm deep, but the peculiarity of that spot is that there is the basement of a ruin under it and someone just put a layer of maybe 20 cm peat or something like that over the rubble and many trees and plants have grown there.
The question is really if a good ground for these kind of devices necessitates a relatively unobstructed "access connection" to telluric currents or if it´s merely a source of electrons if there is enough earth surrounding the rod.
Also even though the rods are at a 10m distance with an unmeasurable resistance between them, is there actually current flowing between the two?
This whole topic is really not as intuitive as electronic circuit theory hehe.
I did manage to get an earth battery going there, but that had only a distance of maybe 80 cm between the electrodes.

At this point only an experiment will determine if your location has good ground with very low resistance.  Try adding water around the ground rod.

You can also try taking your setup out in the country.  Amateur astronomers do it all the time, where the city lights are too bright, they take their telescopes to dark skies in the mountanis or fields.

Regards

@woopy
excellent work.

You said that application of ferrite is not necessary! At in a photo woopy ferrite rings are obviously visible. And you say for woopy that it is good work! Specify it is necessary to use ferrite rings or not? If "YES", that it gives?
Thanks.

Nice clean build, woopy !
Congratulations.

Looking forward to your tests.

Please try to test the importance of the inner
twisted wires inside the tube.
Will this add to the output power or can it be changed somehow or
how does it effect all the circuit.
Many thanks.

Maybe you have a scope and use a small pickup coil ( don´t connect it directly!)
to show some scope shots of the waveforms being produced ?
Many thanks.

telluric currents are very unlikely to be source power its just a natural event that telluric currents exists. IF the source of power was ONLY telluric frequency it would discount all other methods of OU extraction. Nor would it work on ONE earth systems.

I wouldn't worry about your earth so much if you can bang down 1/2" copper pipe 18 inches or 2ft its good enough. For every foot deeper you go increase lights by a very very  slight increase in brightness.

"Also even though the rods are at a 10m distance with an unmeasurable resistance between them, is there actually current flowing between the two?"

True a static meter test will show Mohms resistance or maybe 1 volt and few milliamp. I explained this before its the "bird on the HT wire" you can not see the thousand amps and volts when you are sat on the same potential.

Only when you create an ambient disturbance you tap the Radiant Energy and it doesn't matter if you do this at 5Hz or 5GHz. When its working yes the amps are REAL coming up earth wire.
