Not so fast ! https://en.wikipedia.org/wiki/Coal-seam_fire https://en.wikipedia.org/wiki/Coal-seam_fire
- floatingatoll 5y agoNow I wonder if coal is more electrically conductive than dirt as well as thermally susceptible. Could you ionize a coal vein? Maybe we can transmit AM radio with it and map it with a heavy metal detector!
- Bayart 5y agoIt's carbon so there much be conditions in which it's semiconductor or conductor-like. But even if those occurred naturally, they'd have to occur consistently throughout a seam for it to be carrying radio waves. In any case coal dust should have pretty good electric capacitance. Combine with flammability...
- dredmorbius 5y agoFortunately, California has a very low incidence of coal fires.
