I see no connection to the EM drive. The paper you mentioned suggests an alternative inertia formula, however it doesn't break conservation of inertia as far as I can see. The "theory behind the EM drive" [1] is completely based on classical electrodynamics and therefore it's flawed. Classical electrodynamics conserves momentum and energy. It doesn't mean that the EM drive can't work though, it just means that this theory can't work. [1] I only found this: http://www.emdrive.com/theorypaper9-4.pdf http://www.emdrive.com/theorypaper9-4.pdf Is this what you refer as the "theory behind the EM Drive"?
