Another question. In another thread I have been enlighted to the fact that a hollow charged sphere has no effect on a charged particle inside of it. But, is not the decellerating grids that are susposed to decelerate the alpha particles the same thing? Or does the centrally located structures (magr...

I have 3 or 5 posts on fuel injection here: http://iecfusiontech.blogspot.com/ I have looked and looked and can find nothing about the power ratings of ion injection means. Please may I ask for your help in pinpointing the blog that discusses this. Read this about lusers: http://www.catb.org/~esr/f...

I do not consider your response reasonable. The fusor works, no question, within its known operational limits. Are youtrying to scuggest that the Polywell has actually had 50 years of investigation aswell?? I thought that critisism was kept for tokamak? The fusor's success or otherwise has nothing t...

Polywell has had only a small group of people working for a couple of decades, the two programs are simply incomparable. Tokamak, under the small team of Lev Artsimovich at the Kurchatov Institute, began working towards their first tokamak, T-1, in 1955 and by 1968 were testing T-4 and producing th...

It's all proposals and ideas! 25 years down the road on tokamak, they were already researching neutron bombardment of selected materials. So Polywell is way way behind, then, it does not yet know what the actual problems are yet to even start developing the experiments that might find out what quest...

But, just the physical bulk of this thing will be problematic. I keep hearing that a fusion-power Polywell is ready for building, if only there was the $200M. But it looks like there are many many fundamental design elements and bits of understanding that are missing. Lots of critique over tokamak -...

OK. But what about the magrid. How many steradians of coverage do they represent? This is assuming the alphas will get past the magrid, no? Or do I misunderstand I'm also a bit unclear where the electrons recirculate, if there are ion energy recovery parts where the electron recirculation should go?...

I've had a search for how the Polywell would be fuelled and found a couple of vague references to ion injectors sited at the magrid. Please let me know if there is anything more detailed. What I am looking for is to understand how the device would inject 100Amps of proton ions. That's quite a proton...

I've had a quick search and nothing seems to have been discussed over the exhaust from a 800MW reactor. If you get 3 x 4He forming at the centre with their combined 8.68MeV of energy, they're going to high-tail it out of that 110kV well with ease. They will totally nail and bombard the coils and the...

I was thinking of collisions more like quater to half-way out, rather than just the slow stuff right at the edge. And once ions are scattered half way and heading circumferentially, they would be more likely to then collide with radially moving ions, which would then be displaced circumferentially, ...

For those ions scattered off their radial paths, i.e. with a circumferential component, is there any mechanism that brings them back into a radial path, or do they keep their angluar momentum about the centre? The term 'annealing' has been mentioned a few times. I have no idea what that is, but what...

And you are right that it is 'just a definition'. Merriam webster: 'Confine': 1 a: to hold within a location b: imprison 2: to keep within limits But the divertor (or limiter) doesn't confine the plasma it sees. Why is it called the 'limiter'? - perhaps because it limits?? This *IS* the definition o...

this strength is way to small to stop/ divert the much heavier ions. Dan Tibbets What magnetic field do you think is there, then? I have demonstrated above the arithmetic to show that a field of 0.05T is all that is required to arrest the motion of a proton towards a 110kV potential over a distance...

This doesn't make sense. Reaction force as in Newton's third law and rockets? Really, and, pray tell, how much of the vacuum vessel would the plasma fill if the divertor was not there?? Your answer should then be 'up to the wall', or whatever other physical structure gets in the way of the plasma f...

Can I please clarify this description; Do A) ions go from the edge of the device and accelerate all the way down a potential gradient, through the wiffleball's magnetic surface and into the ball of electrons. If it does not collide, it comes back out, out of the wiffle ball and back up to the high p...
