The Basics of a Plasma Thruster

Plasma thrusters are basically just magnetic bottles that you're heating up using some sort of electrical energy. The exhaust is naturally uncharged, doesn't have electric charge, because what you have are both positive and negative particles shooting out the back. You don't need to do something extra to make sure they're neutral. So there's not a whole lot of stuff to break, except, of course, for the plasma eating the bottle.
