  This is old news. Things are happening very fast right now. The latest
superconductor transition is around 90K, well above liquid N2. Rumor
has it that a 150K transition has been seen. Rumor also has it that a
"dry ice" superconductor may be possible. There is a rub however. These
materials are oxides. No one knows how to make a wire out of them. Yet.
