Just thinking big here, would it be possible to build a giant ion thruster and move the whole planet? How big would it need to be?

(By the way, I'm asking for a science fiction story idea I have. )

Is there anywhere to get an understanding of their process? And how are they making 4000T magnetic fields?

What technologies or breakthroughs would let us build portable neutrino detectors? Will it ever be possible?

Curious what it would take to make ion propulsion work in an atmosphere?

I know current designs can't but what would it take?

Thanks. Those are great. What’s causing the pinch effect though? Why can’t the electrons just flow straight through the plasma?
