It appears you are also ignoring time. The Polywell is NOT a static device, it is a dynamic device.

Speechless...

What happened to the thoughtful oppositions of art carlson?

I miss Art.

Now we have Joseph. Joseph who apparently never learned to tell time.

The sad part is we didn't even start talking about phasing and waves. I was trying to keep it simple.

The relativistic space-time was thought up for the convenient description of the same phenomena, when time and the distances are the different in various frames of reference. For this purposes the Riemannian geometry is used and not Cartesian. So, it is an abstraction.
Though habitual for us Cartesian system is an abstraction too. But this abstraction is well understood for us unlike Riemannian. Now I hear from the people assured that any straight line crossing a circle passes through its center, the charges of ignorance of at least the concepts of space-time?

We talk about the system (machine) having characteristic time of milliseconds and velocities of all particles are too far from speed of light. Be noted that rest energy for electron is 511 keV, rest energy for nucleon (proton, neutron) ~960 MeV.
Has any particle in Polywell the energy comparable to these two numbers?

Why?
Consider it a question.

That is why I asked it. By your response, (I wouldn't call it an answer) I guess you don't know either.

One rumor has it that he was able to have a one-on-one conversation with Dr. N. who was able to convince him that this thing just might work so he decided to wait and see. If so, seems he is better at "waiting" than the rest of us.

Of course, the other is that he just got disgusted and left.

Ooh, I get it! Sorry, just woke up.

The "thoughful oppositions" left with Art. Seems Art left the thoughtless ones behind with Joe

Its like a joke! Only.... not as funny.

Ummm, are you "sheechless" about Joe's statement or krenshala's response?

Joe,
Despite your not-so-vailed insult, I assure you that I do not think that. But you seem to hop around so adroitly in your assumptions that I sometimes have difficulty understanding the basis of your discussion.

You seem to have an issue regarding two-beam instability, which suggests that you either think that somehow beams come into the MaGrid and two or more meet at the center and do something that prevents this thing from working or you think that beams come in and somehow run into a "maxwellian background plasma" and do something that prevents this thing from working, though how this can be TWO beam instability I don't understand.

We've already dispensed with these two scenarios.

Is there another scenario?

It is all about Joe.

Joe,
You are smart. You do not argue well.

I think that most arguing against you are trying to argue that Polywell is anything but a "straight line" crossing the circular center. What makes it work is that enough density in space-time does end up near the center with high enough energy delta to make a reaction. The inbound to outbound to not moving target ratios of these reactions has yet to be understood. (And you should be happy given the construct of your idea for fusion lives within the boundary of Polywell) The main point is that the reactions/densities have happened enough in previous live tests to have the potential of scaling for net power and justify further exploration with more live testing.

Why did you not see the what the fourth dimension was for the simple construct? I am sure is was not because you don't get time-space.

"Enough density" has an unit (number of particles)/m3 or (number of particles)/m3*sec ?

I do not insult anybody. But I am repeating only said that Polywell as well as any other approaches is not ready for commercialization concept. Our disput began from this my point.
And I am not seeking scenarios and two "my" scenarios do not contradict each other. And "thermal" is much wider term than "Maxwellian".

Area under the curve.

Sorry, if this was your point, your manglish (mangled English) hid it well.

As far as I know, no one is suggesting that ANY fusion process is "ready for commercialization". There are a lot of suggestions, heck even outright statements that should perhaps have been stated as strong opinions, that certain paths (tokamak for example) will NEVER be ready for commercialization. Even if/when they reach breakeven, the cost per plant would make the energy therefrom unaffordable.

So far, a number of folks, myself included, still hold out hope for certain other paths, like Polywell for example.
