What's the purpose of this octahedral grid?

Ankovaks, What do you see the purpose of this octahedral grid design is? Is it to be a replacement for the coils used in the current WB-6/7 design? Is it intended to surround the existing WB-6/7 coils? Go inside? You've been very clear that part of what you are doing is ensuring that the currents ar...

FORTH handles it differently. You can only access (without contortions) the last definition of the operation. Example in pseudo code: (1) Define Operation (2) Define Operation (3) Call Operation In such a situation the Call only references (2). Debugging then is much simpler. Well, yes, but.. (1) D...

Re: Why 10-25 times net power?

This whole mess started out with the following: Article on the "Piston" fusion device states needs 10-25 times output gain to be viable. I am a neophyte but have been following the fusion blogs avidly. If a device had a 25% net power gain and was cheap enough to operate less energy costs, it would ...

Consider the analogous 2D case: six equally-spaced magnets, 3 pointing in, 3 pointing out, alternating around the center. If you plot the field lines, there is still no field in the center, and the lines go to the adjacent magnets, not to the opposite side. True. But draw the little magnetic field ...

The thing that always bothered me about that drawing was the directions of the magnetic fields produced by the coils on the opposite faces of the octahedron: if you apply the right-hand rule to the coils on the opposite faces, the resulting magnetic fields do NOT oppose each other. This seems to me...

A fusor works by fusing fast beam ions with lab-stationary background neutrals in a partially ionised [very low fraction] gas discharge device where most of the ionisation is through consequences to electron conduction through said gas discharge. This was not my understanding of how fusors work. Wh...

OK, it's been bugging me for a while that I can't answer this basic question... What is the Magrid? Is it the 6 physical coils? Is it the surface of the whiffleball (i.e., the quasispherical edge of electron confinement)? Is it a physical anode surrounding the core? I had believed that the Magrid wa...

So it doesn't matter if the polywell is a ball of electrons or a spherical shell, the geometry will give the same result to first order. Assuming that the electrons are a tight ball/shell in the center of device and the ions go relatively far outside the electrons, then yes. This is the mode I've a...

Personally? I'd go to a boron dealer and buy it. Pure B11 and B10 are already commercially used and purified.

Yes, indeed I'm confused. And to further extend my confusion I'll argue further. First, my understanding of a a Faraday cage is that it is a barrior against electrostatic fields, it doesn't say anything about what fields may exist within or outside of it. http://searchsecurity.techtarget.com/sDefin...

We seem to be using the noun "ball" and "shell" interchangeably. Do the electrons form a ball, inferring something (more electrons) inside and net forces inside, or do they form a shell, inferring a vacuum inside with no net forces. I'm not sure it matters. The way I envision it the ions travel far...

Dan, What Art is trying to get at is that within a closed uniform shell of charge(of any shape, but it's easier to show with a spherical shell) there is no net electrostatic force on any charged objects within that shell. With a sphere, look at an arbitrary narrow cone whose vertex is at an ion insi...

Re: Zimwalte

Putting two and two together I'm wondering how much of the future of the Polywell was tied to the DDG1000 (Zimwalte) cruisers that the Navy was making? My guess is "None at all." While there will probably always be some pushing-the-envelope new tech in a new ship design, Polywell is still too unpro...

Re: Wiffle ball effect on Alpha's

The acceleration caused by the fields is proportional to the charge, but inversely proportional to the mass. The alphas are about 3600 times as massive as the electrons, so the forces on them are about 1800 times weaker than on the electrons. So the alphas won't be affected much by the magrid. You ...
