The Emthruster: Thrust without reaction?
Perhaps it is not a "true" reactionless drive, since it seems to act on the quantum vacuum (I think). However, the engine is a sealed unit with no exhaust ports, unlike an ion thruster. Nor is it reacting to external forces, as does a lightsail or a magsail. Since its thrust is created and exerted within the device itself, rather than through interactions with the surrounding medium, I think it might qualify as a reaction-less drive for all practical purposes. [NOTE: The above statements assume the emthruster actually performs as advertised Smile]
