It may be a ‘quantum’ device. If so, then the Newtonian Laws go out the window..................
Yeah, if it really works I don’t think the mechanism will be related to transfer of inertia, because that all seems to cancel itself out in this kind of closed system.
Whether it turns out to be quantum or not, I don’t know, but if this is real, it can’t just be the particles slamming into the device and pushing it that causes thrust.
