Using ‘D Tibbets’ earlier design concept: Imagine drawing a great circle through the north and south poles of a sphere. Rotate the sphere 90 degrees about its polar axis and then draw another great circle through the north and south poles. Using the arcs drawn one could configure a magrid consisting...

Note: The preceding argument, relating to both inward and outward directed magnetic fields CANNOT be avoided regardless of the selected coil configuration of ANY magrid design. One must face how to best handle both the inward and outward directed magnetic fields in their chosen design.

There are no "VIRTUAL COILS" because those rings are not complete. The "cusps" are merely places where the outgoing magnetic field lines concentrate, because of the geometry of the coils. Physics-212 stuff, guys. Chapter 28 of my first year physics text (Giancoli, 2008). I'm sure you are only getti...

Speaking of bowed sides. I have been considering the idea of bowing the magrid until the ends of the grids meet at the top and the bottom. Start with a WB6 truncated cube. Discard the top and bottom grids. Lengthen the side grids till they are ~ 2 times as tall as wide.* Then bow them inward until ...

I wonder if ‘bowing’ the line segments of the octahedron would help with sphericity?
i.e., imagine drawing the octahedron line segments about the surface of a sphere.

Thanks for the ‘Nice analysis’ compliment.

Just for comparison, here is the same four coil model shown with all north poles facing toward the core:



Notice the line cusps between the individual coils.

This is a simple planar magnetic model which shows four alternating N,S,N,S poles facing toward the core for simplicity. A somewhat similar magnetic field arrangement would be observed in the case of eight N,S,N,S,N,S,N,S poles facing toward the core in a 3-D octahedron configuration. http://i115.ph...

I just noticed that with an octahedron magrid featuring 8-alternating pole faces using triangular plan-form coils, one could easily attach the coil-form connection nubs at the center of each line segment. The center of each line segment is an area where no cusps exist: http://i115.photobucket.com/al...

Is this an issue? Good question. At the present only the MPGs have had this plan-form. I have read that they were amongst the only other machines to do fusion, so perhaps the condition is of LESS importance in this design than in a round plan-form machine like WB6. Personally, I like the bow-legged...

Just did a calculation on a rectified unit cube. The area of a square face on the cuboctahedron produced is 0.5 square units. The area of a triangle face on the cuboctahedron produced is 0.2165 square units. There are six square faces on a cuboctahedron and eight triangle faces on a cuboctahedron. S...

Just to make sure, am I correct by saying that from the core viewpoint I should observe clockwise currents flowing around all the square surfaces of the cuboctahedron and counter-clockwise currents flowing around all the triangle faces?

Can you guess which? This, of course, is the next logical question. At first thought I would think that it wouldn’t matter which polarity of the six square plan-form coils was observed as viewed from the core (as long as they were all the same). Is there a preferred polarity (N/S) of the six square...

From the patent definition it’s clear that the optimum magrid configuration is an octahedron not a cube. Another member in this same thread (I believe it was ‘tombo’) recognized this back in 2008. Actually, Dr. B never proposed a "cube" polywell and never actually built one either. What he tried to...

Been up all night and all day... Will be back early next a.m.

But they aren't going in the same direction, wrt a radial sight looking into the coils. Isn't it necessary to have all currents going around clockwise, or ac, when looking towards the centre? Else the mag fields will simply curl around the edges and there would be no 'cusp-containment'? What you'd ...
