The 'impossible' thing is slightly misleading. Impossible with conventional mechanics but possible with quantum mechanics

yup, the explanations of why it would work seem plausible... at least to this non-expert. The idea of a propellantless thruster is quite compelling, even if the forces exerted are relatively small and performance falls off with velocity...

It would be good for satellites, and with more thrust (if possible) great for long range travel. In space you can just constantly accelerate because there's no drag. That's why ion engines like VASIMR have been researched: they use a small amount of energy for a small amount of thrust, but they run constantly

Well, ION engines DO use stored reaction mass, they just use tiny amounts of it... and also expend HUGE amounts of energy to do so. They still offer weight advantages over chemical rockets for station-keeping roles, but yeah, this thing could literally accelerate FOREVER, until it reaches C that is...

Right. My point was this could be used in place of ion engines, and would be significantly better since it doesn't require stored energy. Slap an RTG on it and call it a day...
