Re: Summing it up - to date

I count three other threads in addition to this one on this particular issue: 1. Where do the electons go? 2. Energy extraction alternative and -the hot one right now- 3. Electron recirculation. Each of them has some pretty good stuff, and of course there's a huge amount of overlap. I tried to extr...

you mean a bit like a sort of graduated anechoic chamber - an absorption filter if you will? i was thinking of similar sorts of arrangements a while back to mitigate collisions with the grid coils - studying some of the models at http://www.falstad.com/mathphysics.html and seeing how charged particl...

from confinement to ignition to (continuous?) burn

on transitioning from confinement to ignition to (continuous?) burn: can anyone explain to me, what the current plan is to achieve 'ignition' and 'sustained' fusion in the WB, and what happens to our containment model once these states obtain? Just as some background, Ive been reading through 'Aneut...

Wow, 122 comments. Go Roger! Thank you sir. I also had 32 recs for the dairy, thats good for me. but not good enough for the reccommended page. Not a lot of diaries were being published that evening, so my diary stayed on the front page for a while, giving the diary a better chance to collect comme...

Re: Coupled Oscillators and HT Superconductors

(Nice Plasma pics from WB7 by the way. Any neutrons yet?) I think we should stay away from asking Dr. Nebel about specific results that he would be reluctant or unable to talk about. We should respect the fact that he can't answer. The only thing asking will potentially do is make him nervous about...

Running a tokomak in IEC mode (magnet confinement of electrons, electric confinement of ions) would be an interesting experiment. No cusps for electron leakage, but magnetic contours less favorable to stability. erm, how about the other way around - tok in a wiffleball - a spinning plasma (or perha...

rcain The Wiffle-ball was demonstrated on the WB-2 over 10 years ago. It's not so much that wiffle-ball confinement is so great but that mirror confinement in a cusp is so awful. Dr Nebel. Thank you very much. Please excuse my lack of knowledge there. I'm doing my best to catch up :) (Nice Plasma p...

So you're imagining a balloon shaped something like a pizza wedge? Rather than having two, why not shape this wedge like a lifting body, with small control surfaces for manuevering. I wasn't thinking of something in the shape of a zepplin, I was thinking of something more akin to the Aeroscraft . I...

If you are looking for speed, I think airships are entirely the wrong thing to start with; what they are more likely useful for is for slower moving (bulk) cargo transportation; slightly faster than boats, and they can reach landlocked areas. An efficiency oriented (hybrid) idea I have been tinkerin...

Re: The Akron, the Macon, the ... Bussard?

If Polywell's are net Helium consumers, we're in trouble. If they are net producers, let me think: copious helium, vast amounts of heat, fuel is negligible - imagine 100 MPH superdirigibles cruising the stratosphere. p-B11 Polywells are net producers, each mole of boron used as fuel creates 3 moles...
