> Would the basalt capture CO2 more effectively if released into the atmosphere or into rain storms?
Guess: it would do so more quickly, but not necessarily more effectively in the long run to the extent it balances the energy required to loft it. (Even if it's all green. You could just that energy to grind and distribute more basalt to the ground.)
