Funny thing is that crushing rocks could be solution to CO2. Olivine rock chemically fabsorbs CO2 when dumped in seawater. Crushing the rock increases the surface area.
Mining, crushing, and dumping rock are all something that we can do, and should be doable when electricity is cheap and green. It should be more efficient than pulling CO2 out of the air.
