Here's the Polywell thread at the same site.

Thanks Dave.

Without commenting on the validity of the math or anything that's over my head, but this is hilarious:

Fusion by claim of the various designs only happens in the core or center 5% of the spherical devices, the only place by claim that density and ion energy is high enough for significant fusion. So one doesnt have to treat the entire device. Specifically, where do you see Rider mathematically wrong?

The same place as Rostoker, -- pretty much from the start. To begin with, he continually conflates ion temperature and velocity--once again, a useful concept in an isotropic Maxwell-Boltzmann distribution, questionable in an accelerator. That leads him to the assumption of the isotropic collision operator as noted by Rostoker referred to above.

His "maximally efficient system for maintaining a non-equilibrium distribution", the basis of his model, (page 69 if you're looking at his dissertation) is an unnecessary application of heat thermodynamics that leads to the search for "recirculating power," a nonsense concept for an accelerator. It's a self-licking ice cream cone of a model which presupposes its conclusions as initial conditions. You could use this model to prove a lightbulb doesn't work.
