How this works: The magnetic field is bent around a superconductor, leaving the force lines locked in place. This allows the attracted objects to travel in tracks along the field at a fixed position and orientation in height. More
Researchers at Diderot University in France have already created a prototype board that utilizes this technology. Once set onto a magnetized track, it can carry a person up to 220 pounds. You can check out one of their trial runs at the video below, the future is now!
