Now I do not know who you are, but from where I stand Dr. Nebel is the only one working on a real Polywell fusion device, that makes him the expert, he has the data and that trumps theory. I hope you don't mind if I take his word over yours. Feel free. But if you are a scientist, you know that lots...

How about comparing the high-end hopes for polywells to the high-end hopes for tokamaks when tokamaks were in the same stage as polywells are now, i.e. having produced three neutrons? It's easy to be optimistic as long as you are also ignorant. ...Polywell is in credible! I wouldn't call it ignoran...

On what basis do you come by this conclusion? On the last 25 years of research and $25M funding which has produced so much evidence that your conclusion is undeniable?? Go back and read the whole sentence again. Or are you trying to be funny? It is always possible to write in such a way as to be to...

I still don't understand (and have never had an answer when posting the suggestion) why a toroidal solenoid would not do the whole job better. If the whole way Polywell works is some 'multi-species' collective behaviour of ions and electrons, rather than the flat density of both that Art and I expe...

Art, That is no problem if the ions and electrons pass through each other periodically. Right now, they are mixed together all of the time. If they pass through each other, and spend only a small portion of their time in "contact", then that is a small amount of time for energy transport to occur. ...

Of course. But the fuel mixing ratio is a separate parameter from the overall plasma density. Changing the density, without altering other parameters, doesn't get you anywhere. That's all. From my understanding the typical issue with Bremsstrahlung is that the fusion by-products transfer their ener...

The bremsstrahlung issue is independent of density, which is one reason the objections to p-B11 are so robust. Both the fusion power and the bremsstrahlung power scale with n^2. It is? I would think the probability for electrons to have a change in momentum goes up as the density of plasma goes up,...

Sort of. We can assume that if there's energy produced by fusion, we can get it. The question is, how much energy do we have to inject to make up for losses (transport=leakage of high-energy electrons and fuel ions through the confinement, leading to loss of their energy)? If it's significantly les...

Since, the plasma is fairly close to electrically neutral throughout, your going to have electrons close to the ions... Unless, the plasma is "banded" where you alternate layers of electrons and ions like a lasagna. Course I have no idea what I'm talking about. Is it possible to setup standing wave...
