Stubblefield coils (bifilar) and speculations

[protonmom]

Thanks Jeanna, but remember what I said?  I can see photos if and when they are posted to the forum, (as long as they are not too huge...but cannot see any graphics or pdfs that I have to download.  And I cannot see any videos at all.  But that is okay...I can go to the library to view them one of these days.  I do appreciate you taking the time to make them.  I will get to the library as soon as I can.
Now, guess what I have been doing all day?  I had to completely tear apart my new coil and start over.  There was a short, and I still don't know just where.  But it is a good thing I had to tear it apart to fix that, because I found out that Stubblefield was right when he said no cover on the iron wire.  I had used that interfacing, and boy what a mess that was trying to re-do those wires.  I ended up having to use all new iron wire.  And I had already run out of the interfacing, so I had to leave the wire bare on this re-make.  The good thing about that is, my readings were higher already at only the first wind layer.  I am going slow and winding as tight as I can and keeping the rows as even as possible.  I sure hope it turns out okay this time.  I would like to see some evidence that I actually made the thing work for a change.
Thanks again for making the videos.

In the 2 coils I built, both of my wires were bare.  According to what we could determine from the patent back then, it seemed important that the wires be insulated from each other, and the core.  The way I wound mine using the cotton string in between and the cotton layers under and over top of each layer accomplished this.

So yes, I agree that if you insulate from the core, and just insulate the copper wire (or the iron wire) so there are no shorts, it should be fine.  As long as moisture can get through all of the layers and to all of the wires it should work.

This is what I remember about it.

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.

@Cap-Z-ro & all others,

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?

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

Thank you,
