It is not possible to have a magnetic field line that does not enclose current. It is no more possible to have field lines from a permanent magnet that do not go through it than it is to have a closed field line from an electromagnet that does not enclose one of the wires. It follows from Maxwell's ...

Magnetic materials are composed of small dipole magnet regions called domains. Each domain is a small dipole. If one lines up these domains in a chunk to point in the same direction, then this chunk becomes a dipole magnet. There is no way to add a bunch of dipoles to make a magnetic field that does...

One could do an experiment similar to the Levitated Dipole, see http://en.wikipedia.org/wiki/Levitated_Dipole . However, it would have a loss cone similar to a mirror machine because the magnetic field lines go through the solid magnet. The earth is a dipole and has a plasma around it called the Van...

The idea of the Bussard fusor is to use the magnetic field to hold electrons so you get a negative potential in the center. That entices the positive nuclei to accelerate into the center. By holding the magnet rings positive, you reflect any fast moving ions back towards the center, and the design ...

Perhaps it would be quicker and less expensive to hire Indrek Mandre or someone else to follow up on his simulations. See http://www.mare.ee/indrek/ephi . Because electrons cost 10kev apiece, the electron confinement time is critical. The one electron he simulated did not go very far. However, I don...

From http://forums.randi.org/showthread.php?t=58665#27 we find that the electron confinement time is 0.1 microsecond, but we also find that the electrons recirculate 100,000 times. Which is correct? If the life is 0.1 microsecond, then one needs to fuse the fuel in about 85 microseconds to break eve...

From http://en.wikipedia.org/wiki/Mean_free_path , the mean free path of a molecule in air at atmospheric pressure is 68 nm. This is probably comparable to the mean free path of an ion. I think a free electron would attach itself to a molecule the first time it hit one.

Go get a copy of Krall et al. (1995). It will of course explain it in much better detail than I could summarize here.

Nothing newer than 12 years ago?

A vacuum chamber is essential. The best we can do without it is a simulation. See http://www.mare.ee/indrek/ephi/ They simulated one electron. It appears to be able to give the trajectory of electrons but will not simulate electron-electron collisions, or electron-ion collisions, or the influence of...

Thus, in order for a Polywell to be driven in the mode described for the basic concept, open, recirculating MaGrid (MG) machines are essential . This, in turn, requires that the entire machine be mounted within an external container surrounding the entire machine, and that the machine be operated a...

For further technical details about WB6 operation follow the next links with some Bussard´s comments and final results: http://forums.randi.org/showthread.php?t=58665#27 This link seems to contradict itself. It states that electron life is about 0.1 microsec, but that the electrons recirculate abou...

For electron confinement I suggest you to see the next youtube videos: http://youtube.com/watch?v=ao0Erhsnor4 ( www.mare.ee/indrek/ephi/ ) http://youtube.com/watch?v=jmp1cg3-WDY As far as I have understood the "wiffeball effect" is based in that the more electron trapped the smaller space they have...

Pstudier, I suggest you study the DTIC documents available by Bussard and Krall. http://www.dtic.mil/dodsrch/ search for "Bussard polywell fusion" All those papers appear to be just theory, and the latest is 1992. I have seen very few actual numbers based on his experiments. If Polywell is to work,...

I studied plasma physics about 30 years ago. My degree is in Physics, but I spent my career doing engineering in an unrelated field. I was hoping to calculate things like energy and electron confinement time, whether this thing will have velocity space instabilities, etc. Polywell appears to be MHD ...

I do not consider Wikipedia a good source. Well, it is certainly wise to be skeptical. On the other hand on anything controversial, the talk page will present both sides. Quite often the references cited are much more valuable than a google search. Finally, what we discover here should be added to ...
