The positive charge on the ions keeps them in the center region due to the positive charge on the grids. Those ions that do get near the grid will be low energy. Really? Inside the grid there are almost no E fields because the grid forms a Faraday cage. You can not compress ions into a region of em...

Rider's claim that the system would collapse to equilibrium before fusion could occur seems to be definitively proven wrong by the WB-6 results, if I understand that correctly. Did he ever say that, though? His point was that energy loss would always be higher than energy output unless you could fi...

What was Bussard's bremmstrahlung argument, exactly? I remember he said it would be much smaller than Rider had calculated, but I don't recall if he said why. Rider's claim that the system would collapse to equilibrium before fusion could occur seems to be definitively proven wrong by the WB-6 resul...

A Letter To My Congressman

At this point, I'd just like it to be on their radar so that when the WB-7 results are announced they're primed for action. Please offer your thoughts, pro and con. Mistakes, things I left out, things I shouldn't have put in, etc. The initial version will probably be a hardcopy sent to my Congressma...

IMO we will see 10 digit funding from Congress. To speed this along. I think once this hits the headlines Americans will demand it. That would really be something. This certainly would scratch a lot of political itches if it looks viable. I can see major portions of both parties falling all over ea...

This would seem to increase the likelihood that the scant WB-6 results will be validated and extended, and that a serious (i.e. funded into eight or nine digits) attempt at a net power machine will be forthcoming.

to TUNE THE OUTPUT DISCHARGE OF THE TESLA COIL to the water itself I think he's onto something. If you just reverse the polarity of your magnetic monopole and feed the result into an improbability generator equipped with a source of Brownian motion (say, a nice cup of really hot tea), I believe thi...

Yeah, lots of curves in a truncated dodec. Should be very interesting times for the machining folk.

Do we have any idea what kind of concentric diameters we're looking at for a 100MW design?

That's interesting. Is the concentric-pipes cooling method common? It seems like it might present problems in manufacture and maintenance. I can't recall seeing it before, but my engineering experience is barely hobby-level. For all I know most superconducting magnets are cooled this way. Just wonde...

Fission-powered desalinization seems to be a reality. http://en.wikipedia.org/wiki/Desalinization Australia, Israel and Singapore seem to be good markets as well. I think Bussard also had a design for a floating Polywell desalinization ship. If p-B11 can't be done for whatever reason, D-D Polywell f...

Coincidentally, the moon's lunar soil has lots of He-3 absorbed by the solar wind. It's been proposed as a mission reason to go back to the moon for fuel. Why do you think the Chinese want a lunar base so bad? Nah, they're going for the same reason we went there. The economics of lunar mining are i...

The trouble with a tokamak configuration is that the centre of charge for the electron distribution is outside the confinement area (ie: in the hole in the middle of the donut). This is the point Bussard kept making re Polywell vs tokamaks in his speech at Google: like gravity, the electrostatic fo...

Re: A force greater than fusion

Greed - More specifically, intelligent self interest. I am not qualified to judge the accuracy of the physics, but I believe in it, and am willing to put serious money in a corporation trying to build a practical device. Unfortunately, I have not been able to find a way to invest. I know I can cont...
