I'm sorry -- it's much, much more likely that this guy is wildly wrong than him actually finding 1G reactionless engine thrust. It's bad science to outright declare his stuff to be impossible, but it's not bad science to say that I'm not going to spend time on it until he has demos that are being reproduced by others.
Also, I hope he's wrong. Reactionless drives in space are potential civilization destroyers.
