" The core of our technologies use the Lorentz force imbalances generated by our thrusters to generate thrust without requiring on-board propellant. There has been a lot of erroneous information in media articles regarding Cannae’s upcoming launch of a cubesat mission into LEO. To clarify our previous post and press release: Cannae is not using an EmDrive thruster in our upcoming launch. Cannae is using it’s own proprietary thruster technology which requires no on-board propellant to generate thrust. "
