for those that did not know: polywell fusion technology is directly evolved from Farnsworth Fusor research. it looks like they think that the plasma
instability problem smooths itself out at higher temperatures and densities. that was a theory and the research seems to be bearing out that theory.
at this rate why do we need ITER or NIF?
The experiments have to bear out the theory. The history of fusion is littered with unexpected instabilities and complexities which arise in each new
regime of scale-up, and they have always made the problem worse. If scale-up makes things better, that would be fabulous, but there's also the
problem of capital cost similar to fission plants. If the minimum size means really expensive, then it just won't be built even if it works. If you
can make a 50MWe 1st plant that's profitable and successful then you'll get investors and later scale-up as a real business.
For fusion energy we don't need the NIF at all. It's a nuclear weapons program, and I don't think we should be spending more than the basic minimum on
ITER would turn out to be useful even if a different configuration becomes preferred to a tokamak. There are intense problems in materials
engineering & controls which would occur in any practical fusion power source.
It's like saying whether to scrap the apollo program if somebody found a better rocket engine design than the F-1. There's still plenty of work.
