Like a roller coaster?
Electromagnetic - isn't this just a really big linear induction motor? Like what roller coasters such as Disney's "Rock n' Roller Coaster" - use to give riders that zero-to-60-in-3-seconds thrill? If so, maybe there is some other amusement park tech we can repurpose for military use . . . how about using "It's a Small World" for psy-ops interrogations?
