Stubblefield coils (bifilar) and speculations

[dllabarre]

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.

Thanks Bill


@All

Anyone using a magnesium rod, where did you buy it?
I've only found 1 online supplier and they only have 12" magnesium rods.

"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)."

I've read where people wind a spacing material along side the copper and iron wire.  Something like heavy string or plastic line from a weed eater. They then remove the spacing material after the copper and iron wires are secure. 

copper wire / plastic line / iron wire / plastic line

This will evenly space the copper wire and iron wires from eachother.
Of course it's not easy to wind 4 items at the same time but if it was easy then everyone would have one. 

I'm wondering, if you use string or small rope that is the same diameter as your copper and iron wires, if you could leave it wound because it will hold moisture keeping the copper and iron wire wet?

Has anyone tried to leave a spacing material that holds moisture in place?

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.

Very good, jeanna.  You're right.  The Creative Science plan I had strongly suggested to soak the ground with water around each wire for greater current output.  Dry ground would get you less, even nothing.  They said water it regularly; every two weeks at least.

Here's the patent, #600,457:

With the same diameter the tube would have more surface area. You would think you would have more potential with a tube which you may. But!
Electrons basically flow on the surface. If you increase the current they go deeper into the wire causing resistance which heats up the wire. Thats already a fact. In my mind its always been about surface area to increase the potential. What I overlooked is the electromagnetic field itself. In a rod it would be more focused and could make the energy flow more efficient. Even using pointed rods may be better. The higher potential materiel's is a plus as well as mass to get more out.
The big question for me is why no one has duplicated Stubblefield to the extent he did. It all leads back to him and the existing environment and conditions he was in. Its really peculiar how he died.

That is exactly the way I wound my coils.  I used cotton string the same dia. as my iron and copper (bare) wires and left it in place as I believed it would hold the moisture just like the old cotton insulated wire of the old days would have.

I wound the wires bifilar first, and when each layer was done, I then wound the string in between the wires which requires two passes per layer.  I never wound more than 2 layers tho so at 12" long x 2 layers, it is a small coil.
