Judging from the steam pouring out of the contraption, it would seem they're using superconducting electromagnetics. I don't imagine you'd get more than 15 minutes before it needed to be 'recharged'. Also, depending on it's operation, it may require an agreeable surface beneath the board (some form of metal or metal composite). Edit: visited the Lexus site. Yes, it's superconductivity. So, you need to keep your magnets in a very, very cold state for it to achieve its quantum levitation. Unfortunately, you're not likely to be able to do stunts on this board.
