In theory. It could be made with no moving parts and steered via thrust vectoring by varying the location of the negative voltage. Lightweight high voltage equipment like that is very expensive to make at those reliability levels currently, but the idea of an operational window of a year+ doesn't seem like a pipe dream. We'll probably see applications in military intelligence (spying) and drug smuggling before other more civilian uses.

Ahh, okay..."no moving parts". I get it now.
