Here's what your 8" dia coils and feedlines look like on a 2 meter dodecahedron. http://i299.photobucket.com/albums/mm317/tombo1234/dodecrings2meterx8inch.jpg They are mighty fat. If you truncate it and add 20 more coils at the icosohedron points it gets well nigh impossible. It may as well be a clo...

The FPGeneration picture does not show a toroidal sheath. It shows each of 3 coils as about 8” wide in the radial direction and 1” thick in the transverse direction and exposed to the plasma. Wouldn’t that intersect quite a few of its own field lines? The set of points close to their coils would for...

They look like Bitter coils. (said to be capable of 20T in another thread. not bad) I think a Bitter coil kind of focuses the B field through its center hole. The non-circular cross section conductors probably have lots of field lines intersecting the coils (bad). Would that be the case in a Bitter ...
