how on earth is this propelled?? the usual system is this: http://www.rtri.or.jp/rd/maglev/html/english/maglev_frame_E.html where fields are created in in guideway walls to propell the train.... amazing stuff. BUT http://www.bwmaglev.com/technology/default.htm Its easy to see how attracting magnets can make the train levitate.... but how is it propelled?? One is called Electromagnetic Suspension... (EMS) and the other is electrodynamic suspension (EDS). I THINK that the first example is EDS and the second is EMS... if so, how are EMS systems propelled...? The HowStuffWorks site is really inconsistant in its explanation and has only served to confuse me more. does anyone actually get this??????
