Not just a lot of exposed rock surface. But also, there are energy costs for pumping water to the exposed surface. Factoring in the efficiency of the carbon removal from the water, I find it hard to believe it is a good solution.
Wouldn’t it be better if we focus on better sources of energy? I am no expert, but I know about it more than a common man due to my academic background in civil engineering.
