McGuire's patent application mentions using liquid LiPb or FLiBe
coolants.... and not all coils are to be superconducting, if I am reading
it correctly. The patent mentions details of shielding, with thickness
varying from 5 mm to 126 cm. Looks like this is more oriented towards
demonstrating general technical feasibility than merely theoretically
analyzing plasma magnetohydrodynamics and nucleonics.
They are talking about the possibility of levitating the internal coils -
They want to use 2.2T coils, which is a lot less than planned for ITER (14T)
I wonder how much is the "fits on truck" issue a real technical
consideration vs. a way of hype-building vs. patent-law consideration.
Simply saying you can make a working fusor is one thing but repeatedly and
very publicly saying it will be rather tiny speaks of a whole new level of
iron-clad confidence (or in-your-face BS).
I am not so worried about the shielding issue, or even the plasma leak from
mirror coils, which they say have been addressed in the patent, using
liquid coolant and plasma recirculation. The main issue with tokamaks,
exponentially growing plasma instability, also should not be a problem
here, since plasma current is not used as a source of confining magnetic
field (as it is in a tokamak, if I am understanding the stories correctly.
Dave Kirtley (or somebody claiming to be him) also commented here:
"I do think what they are doing is interesting."
- which coming from a direct competitor (Helion Energy) could be high
