I've also wondered about those statements about electrons in the MAGVID text (the USENET posts "GroomLake`Colonel`Reveals'All" by James Stephens), but clarifications from James Stephens is probably totally impossible to get. John Searl claims that it is the neodymium that somehow "generates" electrons that are accelerated outwards by the action of the rollers around the plates, but Roschin & Godin as well as Paul Murad and his team has built crude SEG replicas without neodymium, and both teams have reported weight loss in their prototypes. A physics literate friend and myself have discussed the MAGVID this evening, and he thinks that Ramsauer-Townsend cascades plays a big role here. Also the term "bunching" or "bunch" in relation to magnetic & electric fields is something he talked about at length. He wants to understand how things work before building. My take is the opposite ;-) I will continue my discussions with my friend on this subject ("where do the electrons come from?"), because he's also interested in flying saucer propulsion (he has read Paul Hill).
