A radio-wave trick from the 1980s could keep fusion reactors running continuously

Summary
The coil in question, a central solenoid, works a lot like a transformer. It keeps ramping up its own current to induce one in the plasma, but it eventually runs out of room to ramp. Those stop-start cycles also wear on the machine over time, so engineers would much rather...
