How are they getting the electric currents to the plasma? Seems like the conductor would burn up. If it doesnt burn up how are they dealing with degradation from neutrinos?
Not enough info to say whether it will work or not.
Probably the same way neon lights work....................only huge anodes and cathodes made of unobtainium................
pheromak technology:
Laboratory spheromaks involve very large currents, typically 100’s of kiloamperes and high voltages, typically kilovolts. These currents and voltages are obtained using high energy capacitor banks which are switched in microseconds. The formation geometry is arranged such that magnetic flux cuts across the electrodes connected to the capacitor bank. This configurations generates helicity (twistedness) in the flux tube going from one electrode to the other. With enough helicity a spheromak is formed.

Probably inductive coupling, or maybe even microvave rf coupling. Inductively coupled, long life electrodeless fluorescent lamps have been on the market for a while, and work on the same principle.
