my understanding is that a "funny cusp" refers to what i would call a "saddle cusp" because it looks like [url=http://en.wikipedia.org/wiki/Saddle_point]this[url]. so there are three cusp types: point (roughly z=x^2+y^2), line (roughly z=x^2, y = 0) a, and saddle (aka "funny") (roughly z=x^2-y^2). t...

Not what I said. I am merely expressing my personal opinion that it is hypocritical to say that another project is sucking up money because it hasn't come up with results when he himself ran such a project but doesn't think or suggest that might very well happen a second time. I've no issue to some...

Heaven help anyone who has to build a Polywell out of this!

I believe Coruscant is powered by a multi-decameter polywell of this configuration.

happyjack: sure, technically you can go from yours to a wb-6 without breaking or joining any field lines (actually there would be quite a bit of that, on the individual field line level). but at beta=1 the geometric differences in the mag-field are going to become topological differences, in a clin...

it is not identical to the mag field topology of wb-6. wb-6's mag field topology is roughly that of a cuboctahedron [img src=http://upload.wikimedia.org/wikipedia/commons/a/ab/Cuboctahedron.gif] yours is that of a cube w/line cusps all along the edge. wb-6 only has a few very short line cusps right ...

Six "rectified" "spherized" squares: two problems: 1. there is an odd number of faces at each vertex. so around a vertex you have, say, north in, north out, and... what's the third? you can't alternate polarity. so you're fields are going to combine and aren't going to be very convex to the plasma....

why baseball seem doesn't work

in short, it has two huge line cusps, one on either side.

Real Spherized Tombo: me likey. get 3rd spot on my list. my new prioritized list for modelling/simulation: 1. hanelyp's configuration on pg 1 of the brainstorming thread (radially-aligned coils), 2. mine and hanelyp's cusp conversion / disruption techniques on pg 26 of the brainstorming thread (sin...

now, now, fellows. i presume you're talking about what's been called the icarus' or tibbet's/icarus'. in that case, yes, those have HUGE line cusps. the thing to do, then, would be to keep in mind that people can be sensitive (more precisely, people ARE sensitive, 'cause after all, they're people), ...

Perhaps it is possible to prioritize your list? Also, some of the concept pictures are stick figures I don't understand, sorry. it's already prioritized, in the order i listed them. saw that one coming. ;-) (though actually i'd move cusp disruption / conversion testing up to the second spot. i real...

Further, I'd like the readership (or some subset) to advise on which variants to investigate... for that i imagine the brainstorming thread would be a better source. i'm partial to hanelyp's configuration on pg 1, tombo's inverse wb-6 on pg 5, mine and hanelyp's cusp conversion / disruption techniq...

I know it doesn't consider the torquing forces trying to flip the coils over. (Trying to align the coils N-S) Those forces should be zero if the coils are perfectly aligned and don't vibrate... i think the thing to do with that would be a sort of "perturbation analysis". check what would happen if ...

i just realized that my crazy whacky six-coil design is just the cusp disruption coils on the single-coil octahedral magrid, above, with the octahedral magrid removed.

i suppose my main point is there will come a point where doubling your energy input isn't going to double your ion density because the grid will just bleed off that input energy faster so the resulting density isn't going to change proportionally. and though that point may be slightly higher with a ...

So are you trying to say that if you plotted 'loss' on y-axis against 'grid intercept area' on x-axis then you think you would just see a horizontal line? i'm saying you actually have to plot at least 6 axis. loss, grid area, present ion/electron volume (or density or what have you), ion/electron l...
