There's been some good stuff on superconductors in Electronics lately,
including notes about a company that is using superconducting IC's to make
very fast oscilloscopes.  Cute stuff.

Unfortunately, the newest superconductors are _not_ up to liquid nitrogen
temperatures.  The best I've heard yet was 53 degrees kelvin, which is well
below liquid nitrogen (~70 K, I can't remember exactly).
