Stubblefield coils (bifilar) and speculations

[Michelinho]

As I was reading on the Stubblefield post, I read that people try many different material to achieve greater output. I just realize that the water in his cell might just be mandatory and I explain:

The Stubblefield cell's core and one of the bifilar are of the same type iron and the other one is insulated copper.

The use of moisture or water or wet ground helps promote the formation of iron oxyde and at a molecular level, it performs as a transistor.

We have measured in situ the electronic conductance spectra of the passive film formed on an Fe electrode immersed in a borate buffer solution using electrochemical tunneling spectroscopy (ECTS) and electrochemical impedance spectroscopy (EIS) techniques, and we have followed their changes as the electrode is electrochemically oxidized and reduced. We demonstrate that pre-passive Fe(II) oxide and the passive Fe(II)/Fe(III) film, behave as p- and n-type semiconductors, respectively and that their reversible inter-conversion is mediated by the availability of free charge carriers on the electrode surface. ECTS spectra have been also modeled to obtain the main electrochemical kinetic parameters of the electron transfer through both p-Fe(II) and n-Fe(III) oxides at different sample potentials and pHs values. We find that the electronic energy barrier in the oxide and its dependence with electrode potential and solution pH, determine the reactivity and passivity of iron.

I remember reading that one of the property of iron oxide is that it filters high frequencies and also it being used with boron in magnet compound. Maybe it should be worth investigating?

What little else I have found point there too Iron oxyde and iron is magnetite:

Magnetite is a ferrimagnetic mineral with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. The chemical IUPAC name is iron(II,III) oxide and the common chemical name ferrous-ferric oxide. The formula for magnetite may also be written as FeO.Fe2O3, which is one part w?stite (FeO) and one part hematite (Fe2O3). This refers to the different oxidation states of the iron in one structure, not a solid solution.

The Curie temperature of magnetite is about 580?C. Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in discovering and understanding plate tectonics. The relationships between magnetite and other iron-rich oxide minerals such as ilmenite, hematite, and ulvospinel have been much studied, as the complicated reactions between these minerals and oxygen influence how and when magnetite preserves records of the Earth's magnetic field.

Magnetite has been very important in understanding the conditions under which rocks form and evolve. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity. Commonly igneous rocks contain grains of two solid solutions, one between magnetite and ulvospinel and the other between ilmenite and hematite. Compositions of the mineral pairs are used to calculate how oxidizing was the magma (i.e., the oxygen fugacity of the magma): a range of oxidizing conditions are found in magmas and the oxidation state helps to determine how the magmas might evolve by fractional crystallization.

Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks. Magnetite also occurs in many sedimentary rocks, including banded iron formations. In many igneous rocks, magnetite-rich and ilmenite-rich grains occur that precipitated together from magma. Magnetite also is produced from peridotites and dunites by serpentinization.

Magnetite is a valuable source of iron ore. It dissolves slowly in hydrochloric acid.

From the first paragraph of document: http://www.cosis.net/abstracts/EAE03/13495/EAE03-J-13495-1.pdf

Iron oxide (w?stite) is an archetypal compound in the family of simple transition metal. oxides, being known as Mott insulators.

That would solve another riddle, modern insulated copper wire should work.

Hope I'm still tinking right,

And I thought I was going to sleep. 

If iron oxyde filters high frequencies, it will filter the magnetic bubble created by the bemf. So his cell filters unwanted high frequencies pulsed which makes it a rectifier.

I think I am overenginering the Stubblefield cell.

Good night,

Welcome Michael,

why sleep when you can wrap a stubblefield generator?

Please go ahead and overengineer this thing. I think we have thoroughly exhausted the galvanic elements and no matter what else we did we couldn't get  beyond this.

I am very interested to watch your progress. I think you may have some fresh ideas that will get something going now.

To me, this thing "felt" like a transistor, so I will particularly want to follow that.

I will be away til monday , but please keep reporting.

My only or first question is that  I noticed you mentioned the center of the bifilar wire, I assume this means you twist the copper and the iron wires together to produce this?

Earlier we decided to copy the way the patent named the wires. The unconnected ones he (NS) called 10'2 and later he called the other end of the copper wire the 5 and the other end of the iron wire the 6. I usually call these the 5cu and 6fe or something like that so people unused to this will have a clue.

so, according to this nomenclature, you are twisting the 5cu and the 6fe together and leaving the 10's open? 

Again welcome.

Hi jeanna,

I think I have a tentative scenario.

The 5 and 6 which are the outer terminals on the cell. It is where the load is connected. The two center taps (10) are left open during conditioning of the "cell" but are connected to the control coil after the cell is live. The cell acts like a capacitor that charges from below, and discharges in a load above. When the capacitor discharge, there is a strong bemf that is looped in the control coil that re magnetize the core oppositely possibly alternating between North and South attracting opposite telluric capillaries that blast the core with a strong magnetic current that restart the cycle. Creating possibly the ac effect noticed by some.

The other possibility is that the back emf that race down the primary coil magnetize the core and the back emf rolling around the control coil sucks in the fresh load of telluric current that starts a new cell cycle. That would give pulsed dc.

I was just looking back at the Patent for reference and noticed the lower tip of the cell. the small protrusion of the threaded end with the nut shows an ideal profile for a "look down" probe. Designed that way or coincidental. There you go, more over engineering... 

I am kind of ready to start building, just missing one component. I will get it next week and go from paper to product. When it is done, I'll set it and condition it for a while monitoring the output for live action safely inside. 

Take care and have a nice weekend,

Michel

More over engineering,

As mentioned in the Patent and that just flashed, the cell can be used with the secondary coil attached to the center taps ( 10 ) or without the secondary coil attached to them.

That would give the possibility of higher dc voltage not pulsed as the cells are set in anode cathode pairs.

That makes many scenarios to study. Pulsed DC, DC and AC. Only an analog multimeter can make sense out of this. Digital will be useless and depressing.

Take care,

Michel
