the electrode setup was a concentric ring setup so it was simpler than a spherical setup like a fusor kind of device
the most common fusion concepts nowadays involve magnetic enclosure and or compression, of plasma, and electric charge based acceleration of the plasma.
> Theory for a gridded inertial electrostatic confinement (IEC) fusion system is presented that shows a net energy gain is possible if the grid is magnetically shielded from ion impact. A simplified grid geometry is studied, consisting of two negatively-biased coaxial current-carrying rings, oriented such that their opposing magnetic fields produce a spindle cusp. Our analysis indicates that better than break-even performance is possible even in a deuterium-deuterium system at bench-top scales. The proposed device has the unusual property that it can avoid both the cusp losses of traditional magnetic fusion systems and the grid losses of traditional IEC configurations.
That means it should be relatively easy to verify in a laboratory, right?
As a rule of thumb, fusion is only really vastly better than fission once you turn it off.
That said, I agree there is likely something wrong with the design.
I wonder whether you could detect the increased efficiency well before reaching break even (that wouldn't prove that you can reach break even of course)?
Really, if your not asking for money just a location that's a fairly easy sell. If it doesn't work at all that's no real cost to them. If it almost works that's a cheap neutron source that's easy to turn on and off which is valuable. And if it actually works that's one of those world changing things people are willing to support.
" Equations describing plasma equilibria are derived from the total energy of the system. The MHD equilibrium is shown to hold even for systems where the magnetic field may locally vanish. Through conservation of helicity, confinement is shown to be intimately related to electromagnetic tension. For an axisymmetric device, the presence of a magnetic field or current circling the axis is shown to be destabilising. This provides a simple explanation for the poor performance of some devices for which MHD predicts stability"
there is a cadence between electric charge motion and magnetic flux, and a dynamic balance has to be manufactured.
the addendum describes the magnetic confinement of electrodes to be a source of instability in the reaction.
as well as providing a corrective factor for the mathematics, describing the theory.
Compare that to the paper's figures, starting on page 2.

And Bosi seems to have been at Sydney at the time as well:
This makes me wonder what would happen to this device? Is it a device like the SG?
>> Projectile Accidents: This is the scariest type of interaction, in which the MRI’s magnetic field literally pulls a restoration out of the mouth. The projectile restoration can injure the person with the restoration or, possibly, others nearby.
>> Damaged or Dislodged Restorations: Magnetic fields may not interact strongly enough to actually remove a restoration. But they may still be strong enough to move, break, or deform restorations.
 Informally I watch PBS Space Time and similar channels, but good though that content is, it’s not the same as a real qualification.
