Anybody know about this?

Sure sounds like a lot simpler geometry, and one that could be tested relatively easily.

Last time I saw a notional Q that high was Friedwardt Winterberg's REB-Pinch in 2003. Impressive.

Someone with the proper bakground daring to have an opinion on this?
Josephchikva perhabs?
May I guess that the physics in this case does not allow any predictions of high probability?
It, seemingly, rarely does in the case of devices for production of fusion energy.
I googled magnetized inertia fusion and found this material from 2011-03-30:

I just cant see how a reactor that is burning gold covered pellets of frozen hydrogen isotopes is ever going to be economic. It just does not compute, sorry. If it is not economic, it is irrelevant, no matter how big the Q is.

Must the hohlraum be made out of gold?

I havent seen anyone talking about a hohlraum made from anything else but gold.
The other problem is of course tritium breeding. If you breed the tritium in the burn chamber, you somehow have to get it out of there and then deliver it to the facility where the pellets are made. Doing that without leaks will be fun and/or costly.

The article's author wrote:Slutz and Vesy start with a fairly standard pellet: a cylindrical piece of cryogenically cooled deuterium/tritium, surrounded by either aluminum or beryllium (this is the conductor that the magnetic field acts on).
