A few watts of Continuous 10 Thz lasers hitting K3C60 (a fullerene), can make the material behave as a room temperature superconductor. What still must be done is make the 10THz lasers continuous or have 100 million or a billion pulses per second. This seems like a doable way to make useful room temperature superconductors.

An organic material in a metastable phase behaves a little like a room-temperature superconductor when excited with laser light. The behavior fades almost as quickly as the laser pulse that induces it, the team behind the discovery say that with the right light source, it might be possible to keep the material in its superconducting-like state continuously.
