You cannot continuously extract energy from permanent magnets any

Do you have a citation for that?
No, this is a common observation. Magnets act like springs. You push
them together N to N, and they spring apart, yielding no more energy
than it took you to push them together. Actually, there is some loss
and over time they are de-magnetized, just as springs gradually wear out.
I find no reference which says that permanent magnets are conservative.
And I know of no way to extract energy from them. Countless people
have claimed there are ways, but no one has ever demonstrated one, to
my knowledge. In any case, it turns out Hathaway is claiming the
energy comes from high temperature superconducting, not the magnet.
That also makes zero sense to me. You might as well say: "we extract
continuous energy from the capacity of the capacitor."
