Stubblefield coils (bifilar) and speculations

[the_big_m_in_ok]

When creating a regular earth battery (not a Stubblefield coil) is it best to use solid rods or tubes (pipes)?
Thank you,

I used solid wires of different materials.  Creative Science(fuellesspower), I believe(?), used rods in at least one of their earth battery designs.
It could be either way.

Old style transformer cooling dielectric oil was often made of some kind of "mineral oil" or sulfur hexafluoride(SF6).

Adding oil may or may not improve efficiency of a Stubblefield system? If it was originally used as an insulating dielectric?  Does someone have a definite answer one way or the other?

The patent is the authority here.

It is water. The ground must be moist.
There needs to be a small galvanic "current"" going on.
I imagine the patent is offered on one of the first pages of this thread.

US pat. #600,457

"a novel voltaic couple... while at the same time producing in operation a magnetic field...inductive effect to induce a current in a solenoid or secondary coil." Page 1 lines 38-48.

It is a very interesting patent to study.

It just hit me after reading your post Bill...I wonder how the coil would conduct if was moistened with oil before planting.

As a matter of fact I would say crude oil would likely be best as it is of the earth.

Just a thought.

Regards...

Cap:

I don't know.  On the one hand, the oil would displace the water which may be bad.  On the other, if the oil works as well, or better than the water, it would be "moist" a lot longer.  All I can say is, give it a try.  That is the only way to know for sure.  It is a good thought.  Water does not conduct and is a dielectric, just like the oil used in the transformers.  Now, ground water, with all of its impurities, is a decent conductor.  I have no idea of which way it would go.

Except for in the very beginning of my experiments, I have used solid materials.  I have seen that the solid materials, having more mass and surface area, delivers more amps. (mA's actually)  So, my vote is for the solid stuff.  I hope this helps.

Hi protonmom and all,

I have also started to wind a NS coil.
Using enamel coated copper wire (= magnet wire) and galvanized iron wire. Plastic sheeting as insulation between individual layers of the coil.

After having wound ca. 6 full layers i tested it (with the view of adding more additional layers later).
When I put it into water the readings were not encouraging (compared to my experiments with similar size rod-in tube cells).
It seemed clear to me that I had not done it right.

Kind of desperate I soldered a non-insulated piece of copper wire to the open copper end (10) of the NS coil and let this hang into water as well.
Voltage and current readings went up noticeably.

So I conclude that when Stubblefield wrote of "insulated copper wire" he was really talking about the 'cloth insulated wire' of the time, i.e.
I think the copper has to also be in contact with the moisture/water. So the wire is not allowed to be properly insulated in the modern sense of the word.
Again: The more bare/unprotected copper surface there is, the higher will be the current and voltage reading, according to my findings.

Will have to redo the coil with bare copper wire, employing just some spacing material to prevent contact between the copper and iron (don't know how to do it yet).

It will be interesting to hear about new findings of protonmom.

PS: I don't think the better readings with bare copper are due to galvanic effects or electro chemical degradation of the metals. There is something else happening.
Water molecules are dipoles. They oscillate, responding to the earth magnetic field and the NMR oscillations of the metals, making an ideal carrier for the resulting fields (field changes) emanating from the two dissimilar metals ....
