GE has been putting hundreds of millions of dollars into Super Conducting generator research. The problem isn't just temperature. Once you start flowing more than a small amount of current, the super conductor looses the super conducting properties.
If the power density issue could be fixed, we'd have liquid nitrogen generators. Hell, most of the generators above about 100 MW are Hydrogen cooled to reduce windage losses. Liquid nitrogen would in some ways be easier.
