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?
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?
They expect the pulverised rock to be spread by the blast and distributed on ocean currents, the CO2 is throughout the water column, it moves over concentration gradients, if one volume of water has 1g/L and another has 3g/L then CO2 will move from the 3g/L bit into 1g/L bit until they are in balance
I think they hope the pulverised rock will be spread so it works quicker, not having to wait for CO2 to balance

Dilution is the solution…ocean big?

Thanks, that makes things make a bit more sense.
