Now send some lightning through it, and you have the ability to print magnetic coils in midair aka force fields. Make a whole array of that and you have a launch loop without ever having to erect an arc. Or reduce it in size and print it on demand into the outer layers of a traditional fusion reactor plasma-donut, to dampen minor fluctuations, without constantly modifying the underlying superconducting coils. So cool this actually works.
