These real-world hoverboards and bikes are really helicopter cousins, using rotors or sometimes ducted fans to provide lift. Because they fly low, it looks like hovering, but it's really just a different form of flight. The Lexus hoverboard, which appears to hover a couple inches above the ground, instead uses liquid nitrogen-cooled superconductors and magnets. It also has natural bamboo, which doesn't mean anything for aeronautics but creates a nice luxury feel. In the video, a skateboarder places his shoe on top of the board, leaving us wondering if it actually supports the weight of a human. Since the screen fades to black, it's safe to guess that it doesn't, but Lexus wants people to "follow the journey" at the hashtag #LexusHover. Cool marketing stunt, luxury brand.
