Of course they would! You are generating an electric field between those balls and the ground potentials that surround them. The balls will be pulled in the direction of the e-fields that are 'flowing' down to the ground potentials. There would be no e-field between the balls (they are at the same p...

All agreed. I was trying to keep the flow of text as simple to be sufficient. ELM's are viewed as potentially seeding global disruptions, they are, themselves, not the disruptions. Either way you swing it, ELM's need to be managed as they are an intrinsic consequence to the desired 'H-mode' for good...

As the newly declared "bonafide tokamak evangelist/troll" I guess I am duty-bound to explain this as I read it, as best I can. In a tokamak there are two modes of operation 'H-mode' and 'L-mode'. L-mode is what conventional MHD/Vlasov/kinetic-theory/&c. ostensibly predicts and is a fairly gentle den...

If you think that being in a electric field suppose no energy requirement to fuse 2 proton, you are wrong. No, I don't. Where did you get that from? The argument is that there is no electric field between the protons. See the further detail, below. P.S. don't consider a proton as a capacitor, to ha...

Back of the envelope calculation - reams and reams of caveats may apply: (This is worth exactly what you've paid for it!!! - I like that saying!) Capacitance of a remote sphere of radius a = 4.pi.e.a (e=permittivity) for a proton, charge radius a=0.875fm, capacitance of equivalent sphere = 4.pi.(8.8...

Forget the energy method; the answer is simple. The plates aren't charged. The positive charges (holes in this case, I suppose) want to get as far away from one another as possible, and that means the outer surface of the box. Despite the high positive potential on the plates, the number of protons...

The notion of charges attracting each other is just that - a notion. Actually the notion of charges attracting or repulsing each other is electromagnetism, it based on the observed comportment of the atom. Philosophically we could say it's a notion that we created to represent a comportment of elec...

The notion of charges attracting each other is just that - a notion. What we are actually doing is conceptualising a change of configuration in a potential field and a change of state of that system. In the case of electric charge, we need to find an electric field before charged particles move, and...

"because tokamaks see instabilities at these fluxes, Polywell will see instabilities". That's kinda misquoting me, isn't it? I'm saying that things should be expected if others have had simlar troubles in much the same situation. That is, if you want something to be successful. If I get stuck one y...

I thought you were getting confused with Pacific Northwest Labs there for one moment:

Quite different outfits.

if the core was 1cm radius and 800MW, this would be a total proton flux entering the surface of the core of ~16GA/m2. I think the numbers posited are 10 cm and 100 MW. That would be about 1.6 MA/m2. I'm referring to the table of data in http://www.askmar.com/Fusion_files/Polywell%20Ion%20Focus%20Co...

So what you end up with is a mechanism by which ions tend to lose angular momentum. That's what they say. There was a long thread on The problem with ion convergence in which I detailed (quantitatively) why I don't buy it. blimey! I got to page 5 diligently and saw enough that this is much along th...

Chris, as a non-technical outsider, let me propose what seems to be the problem. You ask questions: great. Then people post links to threads where this stuff has been discussed previously. You seem to then come back and say that nobody has answered your question. well.. Ok I see this perception. Bu...

Alpha sputtering is very worrisome and I don't think there's a good model for how that can work yet. Thanks, TallDave. Now that seems a sensible start to addressing the issue I tried to raise, and from here I can then possibly make contribution!! Regrettably, this may mean that the device will have...

I am just an interested layman, but this has been discussed at length on the forum. The system will need to operate in a vacuum, which will need to be maintained. The pumps that maintain the vacuum will remove the helium byproduct. Only a short length, to the technical detail that interests me, to ...
