- Passive magnetic levitation, which was developed by the late physicist Richard Post in 2000, uses unpowered loops of wire in the track and permanent magnets in the train pod to create levitation. By contrast, maglev requires complex and expensive infrastructure upgrades, such as power sources placed at intervals along the track.
If none of that makes sense to you with all of the technological jargon, all you really need to know is that the “train” goes really fast. Forget flying cars where we can crash into each other, let’s just keep everyone going 760 miles per hour on a train track inside a tube.
