Stubblefield coils (bifilar) and speculations

[jeanna]

OK
This repeat of pics is especially for Artic Knight.

The patent and brochure show details for building the unusual part of the coil. I have come to realize after reading many pages of Tesla's lectures, that certain things were well understood by people back then which are not used anymore and so are completely forgotten.

The use of sparks to 'prove' that there is electricity happening is one.
The use of sparks to create the make and break is another.
Tesla devoted pages and hours in study and explanation of how to overcome the problems inherent in using the spark.

The father-son portrait shows 3 units with the globes in place.

The one outside shows NS in a spot in between 2 generators which are at least 30 feet apart, maybe 30 feet from him in the center.
So, some of the juice could be coming from the antenna effect as well as the teluric earth effect and the small galvanic effect.

He used iron wire and copper wire.
There is a very small galvanic difference between these twu metals.
Except for one, we all used zinc coated wire which has the galvanic effect of pure zinc for a while.

The one I still have planted is one with iron and copper wires wound on an iron stake.
I don't think the iron is soft iron, though.
He specifically said soft iron.

He had an idea lake Gary, to make this something anybody could make from simple and readily available materials.

I hope this is what you want to see.
I have pics of mine, but I think you wanted to see his. There are many others peppered throughout both eb threads.

Here are some pics I relocated of Stubblefield's earth batteries.

These 3 that follow are from the brochure on the "battery".
There is a hand written note referring to how the patent office refused to allow the name he wanted and insisted on naming it a battery.
In light of the inverter/induction coil as joule thief, I wanted to add these to the photo album.

@ Jeanna:

Great post!!!  That tells a whole lot does it not?  Funny how we worked on these and then moved to the joule thief and now.......it's like deja vu all over again.

Thanks.
