Comment on Electromagnetic Levitation Quadcopter [video]Comments−Gravityloss9yhttps://www.youtube.com/watch?v=OI_HFnNTfyUThey could do it with stationary electromagnets. :)−andysinclair9yThanks for posting that, I found it intriguing and ended up watching the entire video. Amazing to think this was back in 1975!−Meegul9yWhat an excellent presentation. I don't have much of a physics background, but this was immediately understandable.−ricardobeat9yI think that's the idea for the boosters that would appear at even intervals in the Hyperloop track. It would be infeasible to build the whole track as one huge linear motor, which is why Musk's paper suggests an air cushion instead.−Gravityloss9yIn the video I linked the other part of the system is just a flat disk of aluminum.
