The idea that graphite may contain in inclusions that are superconducting at room temperature is highly speculative (putting it mildly) and not an idea that is taken seriously in the condensed matter physics community.

Possibly, but a lot of real progress has been made by trying things that turn out to work and then working backwards to figure out how.
