Are we aware of super conducting material that can operate at room temperature? Of course, but it would do mankind little good as the materials exist on worlds not compatible with Earth. The substances would either not remain in a pure state here, or explode or rapidly burn, or poison the Earth when they escaped their bounds as they inevitably would. The answer to mankind's energy needs do not lie in superconductors, however seductive they may be. There are energy sources known to your government, developed and operational, which dwarf by their operation the goal of super conductor developers. There is no need. The problems that should be addressed lie not in science but in politics and the corporate decisions that force archaic energy sources to continue. We are speaking here of coal, oil, natural gas, and nuclear energy. This is the issue that should be addressed!
