Yet another version of the hoverboard has appeared but once again it is of very limited usefulness. This particular model appeared in a car commercial and did not require any special effects, just a lot of money and liquid nitrogen. By implanting $100,000's of magnets in an area and filling a board containing a pair of powerful magnets which are cooled to superconductivity with liquid nitrogen you can indeed hover for about 10 minutes or so. After that time you will need to top up the LN2 as the boards magnets will gain enough heat to lose their superconducting magnetic levitation. The cost to run it does give a better ride than the Hendo board but also requires a much steeper investment. Still, hoverboard! Check out videos and more via Hack a Day.
"It is definitely real: the Jalopnik writer got to ride it himself, and described it as “Unbelievably difficult yet at the same time unbelievably cool, both because you’re levitating and because the board is filled with magnets more than 300 degrees below zero“."
