Joule Thief

[jeanna]

hey jeanna could you pm me with a drawing of that nathan stubblefield generator your talking about if you have one?

It isn't possible to pm a pic, so I made an entry with the pics on bills bifilar Stubblefield thread.

that EB stuff is wicked, ... release a torrent of energy from the earth and NS might have a similiar idea.

Yes.
As I said on the other thread, but it can be repeated here.

After reading those lectures that Tesla gave to EE's and regular educated folk in 1894, I realized there was a lot that was generally known and understood back then that we do not know or understand.
It was particularly about the spark and how it shows evidence of electricity that caught my eye, but there was more of that nature.

Anyway, I have more pics, but these are what you're looking for I think.
The brochure is pretty interesting about how it is an induction generator. (not... a battery)

Have a look.

@ Jeanna:

Those pics are of Stubblefield's telephone device, his earth batteries are the ones in the box that Hans posted. (I have that photo somewhere)  They are quite a bit larger than the telephone coils.  But, what I don't know, and may never know, is if in those pictures of the phone device, were those rods and coils coming up out of the ground from the EB coils?  In other words, were those poles attached to the earth battery coils and we can't see them as they are buried in the ground?  I have always wondered about that.  We may never know.

Yes, I know, but it is what he used to power his phone devices.

Look closely and you see the familiar shape.

Is this what you built ?Bear in mind this thing was enormous . As big as a power transformer on a light pole . There is a picture somewhere showing his inventions and it show how big it was.I estimate it would take over 1000 dollars in wire alone to build this like he did .

Not the one on top.
That is very confusing and for some reason Bedini included it on the same page.
The complex one in the lower pic is what I and several others built.

I just posted more pics from the brochure on bills bifilar thread. It is where he made the statements that it is an induction coil like the well known kind (at that time which was with sparks) and the electromagnet. This is what the patent office refused to allow.

The last pic from the same brochure is where he states that if you put 2 of these things into the ground and connect them up correctly, they can be used to send the voice at sufficiently loud volume to be adequate for conversation.
Have a look. It is a joule thief/EB. I so love this!

That brochure is not generally available and I treasure it. I have it because of the generosity of the librarian at the library in Murray Museum and Bob Lochte who wrote the book "Kentucky Farmer Invents Wireless Telephone"
