Stubblefield coils (bifilar) and speculations

[Michelinho]

Hi all,

I installed the NS cell in the sump pump hole. I drilled the cement layer and drove an iron pipe 2 feet 1/2 into the ground so the tip is about 8 feet under the outside ground level, I hope to catch a telluric current that will feed the cell to high power. I installed a 15 watts bulb on the connectors as monitor.

Take care,

Michel

@ resonanceman ,

Do you have a meter that  measures  inductance?
I would love to see  what would happen  if each  of the  coils on your  toroid was set to resonate at a chosen frequency   ( L C resonance )

Nope, I don't have one but I'll try to put the scope on it and get a few readings and also some pictures for Jeanna.

The  coils  you  have been working on   look great .
I wonder  if your  yellow  coil  has enough power to  drive a solenoid type switch.

Not yet but if it catches a telluric current, it should light up a good size lamp according to Mr. Stubblefield.

For  your  toroid  I think that  0.60ma ( dry?)  is probably very good  considering   you have 3  coils  on there. ....   If I understand right .

Thanks, It wasn't dry but surely not wet all over the coils inside. Yes, 3 rows of bifilar iron/copper wires.

I believe that  most people that  added  a secondary  found that  the  output dropped .

It should not lower the output of the main coil, it produce a potential as the cell cycles in AC which is about half the level of the DC readings. The secondary coil on the green cell is showing a little potential on the meter even if the main coil shows nothing, so I guess the iron/copper coil oscillate as soon as it gets moisture.

Take care,

Michel

If you can find  a frequency  with  your scope maybe  finding  resonance  on the primarys will  boost the AC higher than the DC

@ Pirate,

How you wound that heavy wire on the big one, I have no idea.

My thumb is still sore. I made a special coil winder for that cell with a 12" crank and with a brake cause I had to stop at every 10 feet to wrap the coton on the copper wire with 2 layers cross wraped to help prevent shorts. That is probably why the potential is low for its size next time I wrap cotton, it will be the one that stretches so the layer get thinner.

Take care,

Michel

If it ever gets to the point of needing a spark gap, I found this: http://drsstc.com/~sisg/SISG.pdf

I hope this helps.
