Hum, someone there must be running out of funding. For the pseudoscience, I guess that the mass energy of the photon go directly into warping the geometry of space-time. (and more Zero point energy particles are usually created inside the warp (bubble) than outside...but if the engine can reverse the bubble...then the engine will not acquire its mass...and disappear...?) How exactly the entire bubble can move through another dimension is beyond me. but it sounds like a great way to discover a higgs particle.... Or not...
