Yeah they seem to hide that info well. The "Hover engine" is basically just a big electromagnet. "Hendo hover board uses a magnetic field architecture to transmit electromagnetic energy. One downside here is that it needs a metal surface to hover" That's a pretty big downside. Not only that but it seems to hover barely even an inch even with the giant metal surface and seems to just scrape the surface half the time they're standing on it in the video.
