You probably saw the kickstarter video already, but here is the pitch for Hendo Hover's real-life no fooling hoverboard:
When placed on a sufficiently ferromagnetic surface, the device really does lift an adult and allows them to frictionlessly glide along. There it is, we did it, a hovering board. Let us don our multi-colored plastic baseball caps and throw our bullies into manure in celebration!
Well, maybe not yet?
This is an elegant display of mag-lev technology, but there's a reason why there are bullet trains but not hovercars. Check out this demo of the Hendo Hover "whitebox" which is a smaller-scale version of their technology. Make sure your speakers are on low before hitting play.
DO YOU HEAR THAT? THAT'S THE SOUND OF IMMENSE VOLTAGES BEING SCRUNCHED INTO A TINY BOX.
The amount of electricity needed to lift a person is enormous, Any battery light enough to use on a hoverboard isn't hardy enough to actually carry you very far. The rig on display in the video is an amazing proof of concept, but I don't think it can sustain you for even five minutes, let alone an awesome chase scene. Oh god, and can you imagine the sound of a whole skate park of these things?
