This is a marvelous effect. I wonder if it would simplify the problem of mag-lev trains, especially ones that run vertically along a space elevator?
Conventional mag-lev trains use magnetic force to lift the train, and gravity to oppose the lift. They require complex controls to keep the train car the right distance from the track. I do not think they would work going straight up or straight down. Or upside down for that matter. I guess you would have to have two magnets on opposing sides of a track, pulling and pushing to keep it on the track, plus magnetic force to raise the vehicle. It would be better if you could set the car at the right distance and angle, and have it maintain that distance by physical laws rather than human controls. It might be good for roller coasters too. - Jed
