The only catch is that, unlike Marty McFly’s board, Hendo’s levitation trick only works when the board is sitting atop a non-ferromagnetic conductor — in other words, a solid sheet of metal that doesn’t contain iron or steel. For this reason, you unfortunately won’t be able to ride it around town. Practically, a board like this would be about as useful as a pair of ice skates as a means of transportation, but in a special metal-floored rink (like the one Hendo shows in the video), this thing could definitely be a good bit of fun.
It is a baby step.
Hover-hockey?
Ice skate are more practical.
#3 You can hover along high voltage copper wires.....
