What is a hoverboard?
The hoverboard originated from the movie Back to the Future II. As a futuristic version of the skateboard, the hoverboard floats eerily a few inches above the ground, silently, and without any apparent means of levitation. Creating a technology to emulate these characteristics has proven to be a far greater challenge than we originally perceived. Yet, from the very beginning, we knew there were only a few ways a hoverboard could possibly work. We described them as: (1) Electrostatic Repulsion – an electric charge on the bottom of the board repels a like charge on the surface. (2) Lenz’s Law – a magnetic field on the board repels an induced field on the surface. (3) Geomagnetic levitation – a super strong magnetic field pushes against the Earth’s magnetic field (the inspiration behind the Magnecraft) (4) Anti-gravity – finding a way to cancel or mask the force of gravity (we decided to leave this one alone). (5) Forcefield Air-cushion Technology (FAT) – using forces rather than a physic
