Plasma Propulsion for Palm-Sized Robot Drones - Plasma Thrusters

Plasma Propulsion for Palm-Sized Drones

Military researchers keep building smaller and smaller robotic spies. But reliably propelling the things hasn't been easy. Using flapping wings, tiny propellers, or ducted fans, the drones all have a tendency to break down, because of the itty-bitty moving parts.

Which is why Darpa-funded researchers at Oklahoma State University are working on a propulsion system for tiny drones with no moving parts at all. It uses plasma thrusters instead
