    And does ERW work if the pulverized rock is in a big pile on the sea floor? Or would we have to dig the highly radioactive area up and spread it around the surface?

    Yeah… Doesn’t the carbon sequestering happen from rain absorbing carbon in the atmosphere and then attaching to the rock to mineralize it? Something tells me 6-7 km of ocean might impede that process.

    And does the radioactive water truly stay at the site of the explosion? Or will it be spread through the entire ocean via currents?

    Dilution is the solution…ocean big?

      The ocean dissolves a large amount of CO2, which then, just like in the rain example, can react with minerals. It can react faster if there is more surface area of said minerals.

        Do you know if Co2 that dissolves into water is less buoyant, or is it held in suspension? Or is this relying on the sediment being suspended in the ocean for a while before being deposited back on the ocean floor?

          I am not sure if I understand you. Dissolved CO2 in water of like normal water. There is no crazy difference. If water can get to the rocks, so can the dissolved CO2.

            Oh, I was just pondering the efficiency. If Co2 is held in suspension and only the top layer of sediment is going to be exposed to the carbon in the water, and not to a degree of co2 more concentrated than normal.

      Dilution was supposed to be the solution to the whole greenhouse gasses emissions, turns out atmosphere not … that big.
