electromagnetic containment sounds like the most viable solution. Now how are we going to solve the inevitable heat dissipation problem.
Basically we're trying to mimic the conditions of the sun, and wield such immense power in a very tiny handle no?
Don't think this will ever be possible :)
I think eventually something like a lightsaber would be feasible. I like to envision my Southern descendants having fun by hovering along in their speeders in the middle of the night slicing off the tops of mailboxes.
