When full-scale experiments begin in 2026, the machine should produce ten times the power it consumes.

When they can extract 20% of that power as usable power they might have something, but they will likely have to extract significantly more to operate at scale, as 80% of 100 Megawatts would be a lot of "waste" energy, presuming that most of it would be thermal energy. The efficiency would seem to be a major limit on cycle time. Not very practical if one or two cycles melts or disables part of the machine. I don't have any idea how this will be done. Some sort of macro quantum efficiency?

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
