I'm not quite sure how this works (need to do some reading), but boy is it cool! Imagine the possible uses of this technology. AWESOME.
Edit: Here is another video with some explanation. This is so cool I can hardly stand it.
Remember the movie avatar? The "unobtanium" the humans were mining on Pandora was a high temperature semi conductor. I.E. the same as the material in these discs but w/o the need for super low temperatures. You can see how a material like this would make all kinds of cool stuff possible.
