Earlier this year there was a hoax video with 'Doc Brown' and Tony Hawk and a new hoverboard that was developed. That video was all fun and games until now? Hendo is a kickstarter campaign that claims to have created hover engine technology that uses magnetic fields to levitate an inch above ground (it does, however require a special surface). I can only begin to imagine the possibilities with this type of tech. Did I mention that one of their rewards is a dev kit?
