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 ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
