Stubblefield coils (bifilar) and speculations

[Pirate88179]

@ All:

We don't have AC in the primary, it is DC.  Also, I am still not convinced that the output of the secondary is AC it might just be pulsed DC at a given freq.  Either way, I do think we have reached beyond galvanic here.  I used iron wire, not coated.  I think it was for fencing.  Again, I used my magnet to tell me if the iron content was high.  The rebar I tested did not have much iron at all.  I did used a galvanized iron spike as it had way more iron than anything in the store.  Jeanna has always wondered if the zinc coating played a part in my experiments, either to the good, or the bad.  I don't have an answer to that.  I do know that my large cell put out volts and mA's when totally dry so I think I can rule out galvanic to some degree.  Jeanna also did some work with a compass that showed some strange behavior near our coils.  I think we need to look at this a little more.

Gary is correct in that we have not had a cell large enough to operate a "switch" to generate either ac or pulsed dc in the secondary.  I hope to build that cell some day.  The same with Jeanna's spark gap tests.  Not enough juice in my opinion.

As far as the wood goes, my thoughts are these.  Wood, when dry, is an insulator of an unknown dielectric number. (unknown to me at least)  If this is the case, it seems to me that any insulator would work as well.  This, of course, is just a guess on my part.  I know of no properties of dried wood that would make any difference to what we are trying to do.  This does not mean that there is not one I do not know about.

I used cotton string in between my cu and fe wires on each layer, which I found easier to do than winding cloth around each wire as I went.  This seemed to work well but, it was not as it was done in the patent.  I was pleased with my results but, as Jeanna has pointed out, possibly our results might have been better sticking to the patent.  But, Jeanna has also raised the point that N.S. had God knows how many changes since he filed the original patent.

Where does this leave us?  Experiment, experiment, experiment.  No way around it I am afraid.  Everything I look at these days in the way of energy production seems to always include the bifilar coil arrangement.  From Tesla on down, this seems very important.  There is something here.

I will post more when I can get back to my "energy garden."

The  properties  of the  dry  componets are important   for  replication purposes .
In my  opinion   the  dry properties  go out the window  as soon as  the coil goes into the ground .

Hi resonanceman,

Nice to see another replicator on board to get the Nathan Stubblefield cell functioning.


Hi all,

The NS cell that I moved to a dryer place is picking up strength, it is now at 0.12vdc at 0.20ma and the same primary coil is also showing 0.050vac on the analog meter, the digital meter show no ac. I suspect the sampling rate of the digital multimeter the culprit. Since the sun came out today, I was able to take a few pictures of that cell.

It is composed of 90 ft of copper wire wrapped in cotton coil with a 90 feet 4 strands awg 16 black iron wire twisted. That's the one with the coax running indoors for measures.

Take care,

Michel

EDIT: The coil shows a North pole at the top of core and a South pole at the bottom.

Great Michael!,

I have one coil which is made from a pipe (soft iron and hollow), where the south of the compass needle points to its top. The rest made with various iron or galvanized iron stakes (all solid) show the north point of the compass pointing to the top.

Is yours hollow?

I think you promised me an oscilloscope reading of your coil when you were finished with it? I would love to hear what it says.

My coils that use those same metals (dark brown iron and copper) also show about the same voltage range. The lowest amps was 0.018mA ( 18uA)  last spring with a functioning meter. I don't want to report now with the cap yet because the meter is not right. The highest reading was in April at 0.292vdc and 0.149mA (not much but more than now.)

Also now, I am using a 300 ohm resistor from time to time to try to see what that does. and it pulls it down for a while.

BUT before you turn away from this project, please clip a non electrolytic cap between the iron and copper terminals at the top (10Cu, 10 Fe) and take readings all around especially with the oscilloscope!

BTW, mine always get better with moisture. They get weaker till they die when they dry out.

thank you mucho,

jeanna

Hi Jeanna,

The outdoor cell has a pvc 1 1/2" core with a 5/16" threaded rod 3 feet long in the center that holds the two ends together because my coil wires loop inside the pvc pipe to make the coil like the patent (4 twisted awg 16 black iron wire is rigid so I needed much room). The higher voltage on the core is weak.

All my cells have the North pole on top.

I'll try to get my son-in-law to bring his scope for a screenshot. The cell I gave him must be rusting in a corner of his lab cause he did not test it, too busy I guess.

Also now, I am using a 300 ohm resistor from time to time to try to see what that does. and it pulls it down for a while.

I use a 1 kohm 1/8 watt resistor as constant load on my cells, they seem to gain in power over time, not much but some.

BUT before you turn away from this project, please clip a non electrolytic cap between the iron and copper terminals at the top (10Cu, 10 Fe) and take readings all around especially with the oscilloscope!

I'll work on the other projects but will keep checking on the cells. I placed a cap on the tpu style cell and I get about 5% increase in voltage so far. I'll try to get the scope shot as soon as possible.

BTW, mine always get better with moisture. They get weaker till they die when they dry out.

Mines too but that cell was in water not just moist. 

A shot of the tpu style cell almost done, just missing the control coil where the wires come out. So far the 1st coil (nearer to the core) produce 0.60vdc 0.60ma with the cap on and the resistor as load. The second row of the coil puts out 0.05vdc and the third coil show nearly nothing as output (might get something once the control coil is wound and activated with electrical pulses.

That's about it for today,

Take care all,

Michel

P.S.: The TPU Style cell has 132 turns on each row, 396 turns copper/iron wire in bifilar total in 3 rows, using about 150 feet of awg 12 copper wire and awg 16 black iron wire. I tried to find larger black iron wire but so far it's the only size available at the local hardware stores.

EDIT: The TPU Style cell shows 0.22vac on the analog meter.
