TED: Boaz Almog “levitates” a superconductor

If my jaw drops during a TED Talk, I have to share. It certainly did during this one and during the quick audience shot, I spotted a few with the same look.

I’m obviously curious to hear more about this an its potential. My one question to start, if that same disc being 2mm thick can support a small car, how do you adjust it? It can’t be as easy to manipulate as the very thin example he was using on stage. That thicker one would be really locked into place.
