Re: Bussard's Polywell patent application is finally dead.

so actually no... a lot of plasma physicists are very specialized, to the point where one person of a specialization wont just know indepth information of another specialization. Dont claim that tok guys know the fine details of beam compression, or even something that's more down their alley, like...

Re: Bussard's Polywell patent application is finally dead.

Busard said people trained in tokamaks use to not understand the polywell. That is one more delusion. As Bussard from his side worked on TOKAMAK concept too: http://en.wikipedia.org/wiki/Riggatron And what do you think, people here even not having the regular physics education - programmers, milita...

Re: Bussard's Polywell patent application is finally dead.

Fission Mafia? Are you sure that at least initially fusion energy will be cheaper than fission? What mafia has to do with viability of certain fusion approach? If patents are granted utilizing only two criteria: novelty and usefulness. May be or not that Bussard proposed novel but less useful appro...

Re: Bussard's Polywell patent application is finally dead.

So the fossil fuel industry strikes again? Expediency issue strikes and not interests of some branch of economics taken separately. Humanity needs new energy source not today but needs about 50 years readiness technology. There is not necessity to make big investments today. All the more in questio...

Re: Actual Polywell News!

And of course in the Polywell thermalization of the fusion ions with the fuel ions is insignificant. Of course insignificant? At what number density? In which form energy of electrons injected by electron guns will be converted? If I recall correctly you mentioned desired number density of future P...

Re: Actual Polywell News!

I'm explaining how it's supposed to work. Motion of ions can be considered as combination of two: · harmonic oscillation around the center · chaotic (thermal) motion Because they are going to increase B-field strength from 0.8 to 10 T, so in12 times, and expect that number density will increase in ...

Correct.
93143 wrote:The electrons are fast where the ions are slow, and vice versa, which is one reason why the plasma doesn't neutralize.
Dubious too.

Re: Actual Polywell News!

The statement of the first quote: The absence of a large externally driven plasma current leads to many attractive features: Stellarators are inherently steady state, stable against external kink and axisymmetric modes, and resilient to plasma disruptions. Wrong statement. Not yours but developers'....

Re: Actual Polywell News!

Any donut machine (maybe more types of machines) that has a significant enough pressure gradient has bootstrap current. Right when has has a significant enough pressure gradient. Now please inform which earlier stage (for example C-series) stellarator had and when and what machine such current was ...

Re: Actual Polywell News!

but that doesnt have any ohmic current in it though, which can be wise, because ohmic current confinement cant be steady state. And please define what do you mean saying "ohmic current"? Iduced current? As Ohmic heat is produced by any current if there in conductor (plasma donut in our case) is a n...

Re: Actual Polywell News!

So you may ask, why dont they do it this way? Well, politics and also I guess tradition. Polytics that forces so many Governments to spend billions for wrong program and to stop right? "do math himself" "100% stable all the time" Hahaha-huhuhu-hehehe And so on Please provide also link of bootstrap ...

Re: Actual Polywell News!

I wrote a summery of stellarator work, and yes there's sims and experimental results to back the claims that having 3D shaping coils would make tok current instability problems go away. Wrong. Real experiments showed that toks are more stable. After which stellarator C4 or C5 (I can be mistaken in ...

Re: Lawaranceville E-Newsletter

Recently here was quoted an Australian paper on Polywell running at low beta. The question is: why low if high possible? Why not just ask them? I am sure they will tell you. They are very willing to talk. Or is it the answer doesn't fit your argument? Why I should ask them? My question is quite rhe...

Re: Lawaranceville E-Newsletter

Objects seen in the mirror are not so close as they may appear. Absolutely correct. Also recall that mirror in which the most people see at various fusion approaches is corrugated. And all reasonings of those people about money needed for making commercial fusion is very ridiculous. As very brief k...
