for kick-a$$ technology?
I was shown a piece of superconducting material that they actually use at Cern once during a lecture, a piece of material with a cross section of no more than a square inch (well, maybe a little more... like 1,5 square inch) that they pass 15.000 amps through. Pretty amazing. Obviously that doesn't work at room temperature, it needs to be cooled down to only a few degrees Kelvin in order for it to become superconductive.
And has the Large Hadron Collider destroyed the world yet?
