Stubblefield coils (bifilar) and speculations

[jeanna]

Nice job!

@Jeanna,
I missed something here.  Where did you first start talking about a Dome?? 

Oops, I guess I posted it on the wrong thread! It is easy to do that these days.
I have a dome frame in my back yard. It is made of electrical conduit tubing. I walkd behind it to install this year's EB and one day, I grabbed some speaker wire and strung that from the south end of the 30 footlong EB to a place on the dome fully expecting the volts to rise. But they did not! they went down. Then Bill reminded me that when he added some very big thing his volts went down but the amps went up.

I am getting a new cheapo meter that can read amps this week so I will continue with this. [I honestly cannot tell you where the original post was.]

Now,
I must say this...
"Do not bury it!!"

Stick a long metal post into the ground and make it so the NS gen can be connected to that post.

Al the clear pictures have a long (3 foot long) post where the patent has a short bolt.
All the clear pictures have 2 in clear evidence. Even in that family protrait there were 2 enormo barrel shaped Generators that were 3 feet above ground and there was a pair of them.

I think you might as well benefit a little from our failures. I am really sure the only thing that is buried is the end of the post!

Also, if you can, make 2 longish ends on the top. I am talking about the wire ends we called the 10's. The ends of the wires that are at the beginning of the windings. They are the pair that is buried below all the rest of the winds.

I am so glad you have gotten this far!

Now, to get you a scope somehow.

Renseek posted an open source scope that works on a sound card.
I just don't know how fast a sound card frequency will go, or rather how much higher than audible sound it will work??

Also, Jeanna, what ever happened with the cement pots setup you made?  Can you direct me there also?

Oh dear, I was hoping you could do that. It must be on localjoe's thread in the winter. I know it was raining a lot during that time, and I had learned how to make cement so um...
I cannot find the pic but something else from around then it was dec 17, 07.

Did you want the data? or did you want to see one. I still have them. One still has carbon granules in it!

jeanna said:To be honest, I looked at Stubblefield's patent drawing and didn't understand it.
(Some patents are purposely like that.)

I understand.
I read the patent every day for probably 40 days.
The only thing about this patent that is sooo confusing is the junk he was forced to put in there by the patent office.
They would not grant him a patent unless it was a galvanic battery, which it was not.
So, every reference to it being a galvanic battery needs to be erased, and the whole business about putting it in a jar is added for the patent examiner too, and should be disregarded. But HE wasn't trying to hide anything. He was trying to promote something nobody understood.

I believe the NS generator is like a buried transformer having a primary hooked up to two electrodes of differing metals, also buried?

Please see my advice to protonmom about the stake in the ground and not burying it.

The secondary is the power takeoff?
For a center tap,(like a transformer?) your dealing with AC?
Only one wire has current?  The center tap?

Yup
The load is off the secondary. He says a load can be off the primary but that is in the galvanic part.

The way I have hooked it up right now, is the twisted centertap is connected to the southern buried zinc nail which is 15 feet away from where the meter is. There is another set up at the north end just the same but to the carbon probe.

The speaker wire may also add to the electret effect?
A metallic dome---ungrounded---can generate a fair amount

Well, ya gotta use something. I am using more wire than before because I had such little galvanic action from the earth before, and I was using 24 gauge tele wire single strand. bill was using 14 gauge hook up wire, which I am using for the 9 foot apart probes in the ground EB.

The dome is very much grounded

Thank you,

I am getting 49 mv ac on top of anywhere from .845vdc down to .245vdc. The ac component does not seem to change... more to come here.

Here are some pics from the brochure provided by the pogue library.

Also 'in the ground' and 'buried' are used but the picture shows that only the stake is actially in the ground.

@jeanna,
thank you for posting the two text copies from the library.
Especially the first text scan with the info about one of Stubblefield's coils (core/coil length 7.5 inches, wire length longer than 100 feet).
In that first scan it also says "Figure 1 here refered to".
Do you also have a scan of this "Figure 1"?

Some more thoughts:
You wrote that you think that Stubblefield did not use a switching system to make/brake contact between 5&6 in order to get induction and thus AC in the secondary, but that he relied on some kind of natural frequencies for induction.

I think he would have used a switch. Yet, using the coils for phoning, he would have used a microphone as the switch.
Applying the microphone between 5&6 the magnetization of the primary and the iron rod would have changed modulated by the microphone. He would have then been able to pick up that signal with a receiver, stuck into the earth somewhere else.

So NS coils can be used for 4 purposes
1: electromagnet
2: power generation of DC in the primary
3: power generation of AC in the secondary, using a proper switching mechanism between 5&6
4: creation of a modulated signal to be transmitted into the earth as a magnetic signal by means of  the iron rods, to be picked up by a receiver.

@protonmom,
the current reading obtained with your new NS coil published in
http://www.overunity.com/index.php?topic=4455.msg197009#msg197009
seems to be 92.5 on the 200 mA scale.
So the current output is 92 mA. This far surpasses any result I was able to obtain so far. Also the voltage (0.83 V) is quite high.
Congratulations.

Can you please give some details about the wires you used and about construction?
Or post a photo of some wire samples?
Bare copper wire and bare iron wire?
Or galvanized iron?
What did you use for insulation to prevent direct contact of the two wires?

If you attach a paper clip or small screw to a piece of thread to make a kind of pendulum and then dangle the screw in front of the coil, won't it be attracted to the core, when the wire ends 5&6 are shorted/connected or while an Amp-meter is attached between ends 5&6 (which is the same as making a short circuit)?

Or can you go round the coil with a compass (with 5&6 shorted), to see if it reacts?

It would be great if someone could get to the point that the core gets magnetized by the flowing current.
Winding a secondary before the core's magnetization is confirmed, makes little sense, in my opinion.

Thanks mom.

@Jeanna
I would think if your dome was pyramid shaped you might get a jolt or three.
I take it the dome is just dome shaped.
On the cement pots, I just wanted to find out what YOU found out.  I can search some more for that info.
Thank you for the Pogue stuff.  All of that helps
You say not to bury the EB and I wont.  I guess it is fortuitous that I made my eb in the way I did with the ability to add on if so needed.  I can just add more all thread to the core for the "post".

@Oscar
I agree that NS must have used a mic as a switch, only I always thought it was the telephone receiver he used.
As for how I made this latest eb, I used all thread as the core inside a hollow steel pipe.  And wooden discs for the ends.
I wrapped the core with cotton sheet material, then started winding the layers of fe galvanized wire, and cu romex.  The romex cu was wrapped in cotton sheet strips.  Each layer was wound tight with 21 rounds on the first layer and the rest all ended up to be 20 rounds.  Don't know why I could not make them all 21 rounds.  Then each layer covered in the same cotton sheet material as the bolt.  (same as the strips, too...thank you Martha Stewart)
I will try the paper clip in a minute and post that.  As for the compass,  if I held it over the core, the compass pointed to what I believe is magnetic north because when I remove it from the core, it points to the north it usually does.  (does that make sense?)  If I hold the compass near the bottom of the core the needle points towards the core.  If I hold the compass in front of the top of the core it points away from the core.
I will get back with the paper clip test shortly.
