    You'd get a cold arse sitting on that thing, and it'd be very energy inefficient to keep the material at -185 degrees. Cool none the less.

    We already use this technology for transport. Ever heard of mag lev trains? It's the same principle.

    That's pretty cool (pun intended)

    Not sure it's the exact same thing, otherwise why would this be showcased years after Maglev trains?

    The differences are slight, but the effect is the same - superconducting magnets used to hold an object in the air. Plus this technique (specifically, quantum locking/flux pinning) has been around for at least ten years. Maglev trains have been around a fair while longer, but they haven't always used superconductors.

    Having said that, currently maglev trains require 'hugging' of the rails, whereas quantum locking means you can properly hover. It might be feasible for a hover car with room temperature superconductors and roads made of strong magnets. Unfortunately, there isn't enough neodymium in the world to do that.

    It's not the same technology.

    With this, I believe, the difference is that the magnetic field is no longer affecting the object with parallel lines. As you can see, the object can be rotated and it will hold its position. With conventional magnets it would either re-align or just fly off.

    No, it's not the same technology but it's a very similar principle - using superconducting magnets. The difference is that this 'locks' the car in place. However it doesn't look especially secure as the guy can move it with his hand without too much effort. To me it looks like a car would get blown off the road by a decent gust of wind.
