its a very well known process basically it is your campfire in the garden with wood then you put out the glowing coals of cour camp fire put it into water to stop the burning and then you dry it on air... result is very clean coal.
humans do this for 1000 of years: https://en.wikipedia.org/wiki/Charcoal_burner
so stop talk bullshit the need for coal from coal-mines are "zero" because all the coal you need to make photovoltaric power plants can be made by organic wastes and classic Charcoal burner processes.
just think about this: many houses use wood to heat their water and heat the house in generall if you do this with photovoltaric solar power plant then less and less wood from the forest is burned all the wood you save can be used by charcoal burners who then produce clean coal.
and also the coal made by this is cleaner and more pure than natural coal...
