Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[turbo]

Hi Mr Spates
That looks like it but i have somewhere a high quality document.
I will try to look it up this evening.

@ Marco

You mean this?

Hans, do you know how much electricity it takes (took) to vibrate the soft iron reed on that early loudspeaker? I'm not interested in making sound but real curious as to that reed moving up and down. I'm considering building one and was just wondering how strong and how far that reed could be made to work.

Thanks

David

Moving coil ammeters are based on the same idea. They are capable of picking up microamps.

Hello Folks,
Sorry ive been mia my girlfriend broke her ankle and got a concussion so I've been playing mom.  At least they gave her ample pain killers.

Ive finally got a little time this weekend to perfect the relay im working with so hopefully i'll be on my way to integrating that soon.  As for the rotary gap im still acquiring parts.

@Marco

Welcome .  I don't know how much of the thread you've made it through so far so heres the long and short.  We started with a galvanic table and different metals in either sheet or rod form .  The farther apart on the table the better the resultant voltage.  A few here have successfully isolated cells meaning two pieces of metal with a flower pot, but those were our early experiments.  A side focus has been constant throughout on the Nathan Stubblefield "Earth Battery" and wireless phone system.  In the past few months our main focus has been on the Stubblefield earth Cell and the results have improved greatly.   Make sure to not get confused when reading the bedini page and others about this cell because half of them are wrong and cant read.  After exhausting reading of this patent we all came to a better understating of it and built our cells from that principal.  He describes two physical devices in this patent. The cool part is this cell has great potential.

"The Primary" Coil is a bifilar wind of iron/steel wire and copper wire wound on a zinc or iron bolt/ threaded rod. The primary wires are insulated from the bolt/core with cloth as well so no electrical connection is made. The wires wound side by side all the way down and then back up no 90 degree cut like one would use in other circumstances.  The iron wire must be insulated with cloth or fabric eg something water permeable , Theres a few audio stores that sell cloth tubing like a sheath at any diameter to suite your wire. The larger the gauge wire the better , more metal in essence. Im using The uninsulated strand of copper from  a length of romex and some steel stranded wire/thick cable i found on a large spool in the basement. Make sure to insulate the separate layers meaning once wound from top to bottom take a piece of cloth and cover that whole layer and the wrap back up the iron bolt. 

This will yield a reasonable ammt of power as it is if one wets it.  Our highest readings were somewheres around .9 v 80 ma so plenty to run a few novelties but here is the good part.

A layer of insulation cloth should be placed around the primary when completed and the the secondary should be wound on that.  Single peice of wire most of us are using magnet wire if that far, and bruce has some litz left which should be cool.  after that is wound with as many layers as wanted the secondary should be secured.  The secondary wire can be insulated in mica, varnish plastic or any of the normal ones. 

So you wet the thing down, take one lead of the copper from the primary and one lead of the steel wire and touch them together. if this connection is held it makes what NS reffered to in the patent as a SELF SUSTAINING ELECTROMAGNET. the secondary in turn is hooked up to a mic or telegraphic relay .

The EARTH BATTERY is actually what he refers to as a PRACTICALLY SELF GENERATING INDUCTION COIL.  It states All that is needed to Make This device work is the normal make and break of the connection between the wires 5 and 6 in the patent which are the copper and the steel/iron wires from the primary their other ends are just left free not touch to preserve the character of the electrodes it states.   Now when you make and break that connection in the primary it disturbs the secondary and  ac voltage/ current shows up on the secondary wire ( Litz or magnet wire).. The faster i did it the higher the ac readings were from the secondary. So with a relay to preform this function or a passive rotary spark gap this can be achieved.   

This is where were at now and working on both avenues, The relay can be built into the cell itself on the top with a springy piece of metal and a contact point.  when the connection is made the center bolt will act as an electromagnet momentarily and suck the springy metal towards it breaking the connection and releasing it back to the contact point for the process to happen over and over again.  The "relay" is self powered from the copper and steel/iron terminals from the primary. This is one testing route im working on.

I think it would be more promising if someone were able to use a rotary gap on a hobby motor powered by a double a or something with a potentiometer on it to adj speed/freq that way the output of the secondary could be tuned since it directly relates to the speed of the making and breaking of the primary.
Feel fee to ask us for pics or whatever else you need to get started if you want to build one. But electronics knowledge is always appreciated even if you don't have time to build
                                                                                                                Thanks for your interest,
                                                                                                                                                  Joe

@ Joe:

Excellent synopsis of our progress thus far.  I am still experimenting.

Hi All,

As some of you may know, my scientific background is as an experimental biologist. I only used this in my career for 2 years and that long ago, but some attitudes die hard. I was having a hard time with the 'spray' of new elements that were suddenly added all at once when we shifted to making the NS bifilar coil with a secondary wrapped over that. I just needed to isolate some of the elements for myself. And so, I will share with you what I did today and what I found as results.

Here goes:

The following is a NON-GALVANIC, BiFilar winding both without an iron core and WITH an iron core. (reflecting the coil body 4 without and with core piece 1)

I wrapped a plastic drinking straw with a bifilar winding of 24 gauge copper and 24 gauge galvanized steel. The copper is a piece of plastic coated telephone wire.

There are 50 winds of each wire per layer and 4 layers. I imperfectly covered each layer with tape to make a separation of the layers and to make winding easier. (I probably should have make a more perfect separation, but since it is dry I may have escaped trouble here.)

I attached DMM probes with clips onto Cu terminal 5 with Red + and Fe terminal 6 with Black -.

1- touched Terminal 10 Fe with a magnet.
=zero volts or amps

2- Shorted terminals 5, 6
= zero

Edit: for clarity, I touched these terminals with one hand on the Fe wire 6, the other on the Cu wire 5
3- with DRY fingers, I pinched terminals 5, 6
0.050VAC-0.100VAC (50-100 millivolts ac!)
0.205VDC
0.3u(micro) Amps

4- with WET fingers (saliva) I pinched terminals 5,6
0.700VAC
0.500VDC
2.9-3.0 uAmps

Now, I added a galvanized sheetrock screw inside the straw. It is almost as long as the winds. I repeated the tests.

5- with DRY fingers, I pinched terminals 5, 6
0.100VAC-0.200VAC
0.220VDC
0.1-2.0 u(micro) Amps (this slowly rose over 10 seconds)

6-with WET fingers (saliva) I pinched terminals 5,6
0.400VAC
0.500. 0.470, 0.450 VDC in 3 successive hits
3.7, 2.7, 2.5  uAmps in 3 successive hits

There are also 2 results using a compass.
(Remember the whole thing is non galvanic and dry.)

The bottom of the coil pulls the S pole of the compass to itself.

The sheetrock screw that I tested and which showed ZERO effect on the compass before going into the straw had a very strong effect on it when I removed it from the straw after only a few minutes of pinching and testing!

The head of the screw that was for a short time at the top of the coil by the terminals, now has a strong N magnetism.

Ahh, I feel so much more informed. (Don't you? )

Thanks for your time reading this,

jeanna

Edit:
P.S. There seems to be an amplifier effect. If I pinch the probes of my dmm I see around 0.020 VDC (this changes with my brain chemistry, of course ) BUT when I pinch the terminals 5,6 I get 0.200vdc. This is an amplification of 10 times. Of course, I could be misunderstanding what I see.

I also do not read any amps or vac which could just mean they are too small to read.

I also do not read any resistance from my fingers which I had expected.
