Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[MW383]

And here is a cross sectioned model of the coil. This very difficult to work with on my machine, crashes or takes forever. And that is on a brand new Dell cad station w/ i7 cpu, etc... I need to find a less stressful way to model this damn thing.

At any rate, it looks suspiciously like the cross section in the patent. It should be noted that this is bifilar wind (see previous pictures) It should be further noted that dimensionally, each wire is .048" + .012" fiberglass = 0.060" total diameter. So keep this in mind when looking at the wires that appear in direct contact. Both copper and iron therefore insulated. Due to constant computer crashes, I was not able to color code things or model up wire + insulation seperately.

smaller picture shows a bundled iron core stuffed in.

In general, I'm a firm believer that an organized construction will provide solid magnetic field gains via proper localized relationships. Some of my original posts last year hinted at this but now that I look at the 3d models, I am becoming convinced. Thus my interest in insulating both wires so that windings can come out just like my pictures. I still think insulation thickness between layers plays a part in local field games happening here. I guess what I will do is build a simple 2 layer coil having different insulation (battery separator) thickness and see how far I need to get layers away from each other for best results. A magnetic field expert (not me) needs to perform a layout on how things will work in organized coil construction. Opinions welcome on this subject...

Doesnt look that intensive. 32 bit or 64 bit Os? A plain background without lighting effects may speed it up. A Plain black coil and size it down may be quicker. Is the i7 the extreme 3.33 with the 12meg l2 cache?

Computer = Dell Precision T1500. 2.8Ghz i7, 4GB RAM, 64bit OS and 64bit Solidworks. I'm not computer expert, just use to run CAD.

So here are some colorized pictures and a little picture of field lines in a coil. I see this representative for the iron windings. Copper would have the same but it will get pounded by the stronger Iron based field. There would be opposition and overall weirdness in my opinion. This assuming both iron and copper running same polarity. Should Tishitang's logic be applied, run copper in one polarity and iron in opposite polarity, now the game gets real interesting. He has various diagrams and texts that talk these theories through. There are other theories out there that are similar. A proper coil construction would enable one to easily test all of them. And that is where I am quickly headed.

If you took a piece of graph paper and rolled it into a tube it basically shows you how the fields intersect on this coil with iron wire. Thats how Im seeing it.

Not sure if this has been brought up yet, so sorry if a repeat. In looking at patent figures further there can be seen various inconsistencies in the representation of primary windings.

Figure 2 seems to agree with my modern CAD from bottom 2/3 coil standpoint.
Figure 3 quite different from either Figure 2 or modern CAD.
Figure 3 wire ends on one side does not agree with number of winds (assuming one continuous wind in down/up/etc... fashion)

So are figures just figurative then? 

I have built coils with one wire that went down/up/etc... This is highest resistance way to wind these things. I would tend to think that there are magnetic field implications with this winding method. (scamble winding seems preferred in secondaries but do we want it in primary?) I have produced CAD that indicates all same wind direction that could easily be wired in a parallel fashion (lowest resistance). In fact I have built small coils this way that were indeed stronger in field and electrical output. 4 wires would still exist, 2 per end of coil.

So forget patent drawings...What makes sense to do? Scamble wind multiple layers with single wire OR a more structured approach? From a field standpoint, what makes the most sense? Any opinion welcome....


Perhaps winding method means little, or effects efficiency to a small degree only? I guess I still lean toward having a uniformly structured system.... I am doing more cad that is based on cross sectional view and field lines. Should give a brief view of what is happening in this coil. I studied many magnetic field photographs for different coils and it is quite facinating to see both localized fields as well as global fields in these pictures. Also re-read induction, self induction properties. If I remember right, NS coil described as high self inductive with low resistance. It is obvious this coil has high self induction. Everything packed tight and next to each other, ferrous core present, ferrous windings, etc... We can wire for lower resistance. Maybe that is the extent of what we need to worry about in the primary.
