Do we have a long term solution for all the toxic waste that coal power plants are blowing into the air and the radioactive ashes that remain? Nuclear waste seems like a tiny problem to me in comparison.

Also, people seem to be more interested in nuclear waste than in coal waste, so I expect more sophisticated solutions.

Stop burning coal is the long term solution.

Short term solution is similar to nuclear, just gather it in random places and hope you've gone bankrupt before anyone asks you to pay for dealing with it because if you pay up front then you are obviously economic self-harm and people would move straight to the long term solution.
