No. This is a ion thruster, a class of thrusters which already exist and are used in various satellites. They carry a propellant (xenon), then use electricity to accelerate and shoot the propellant out the back. This provides extremely efficient, but low amount of thrust (like a nudge).

This development gets rid of the need to carry propellant. They satellite will scoop it up from the atmosphere, saving weight and prolonging life.
