No, you get it now at liquid nitrogen temperatures (77K), which is a lot cheaper. Around 131K is the record, although higher temperature (160K) is possible under pressure. There is no restriction IN PRINCIPLE on how high it can go. A similar thing to superconductivity (superfluidity) is observed in neutron stars. But finding the right material is the main trick... It turns out that the right material is a copper oxide. In other words, if you oxidize copper, you get it to superconduct at high temperature. Weird -g- But these materials don't go above 160K
