From what I understand (and that's not necessarily very much), the arc flows
through a path of ionized air molecules. The high voltage current maintains
the ionized state, but even after the current is gone, some molecules are
still sitting around in their ionized state. That's why a Tesla coil arc
can get longer and longer in still air. Now if you're waving around this
light sabre, your creating a thin cloud of ions all around you. Soon the
arc is going to be free to go wherever it wants. Yes, you'll have to find
some means of controlling it. I'm sure magnets could do the job if they
were huge, but that's not a solution.
I've wondered about this very thing, too. I've been thinking maybe
ejecting some kind of directed plasma from the handle would do it. By that
I mean that you're producing the plasma inside the handle, and then
forcefully accelerating it outwards, perhaps down a tube with pinholes all
along it. But we're talking serious energy here. I wish I had better
