CO2 problem solved, by seastars

They have nano nickle on their shells, which converts CO2 directly to concrete....

ok, not directly to concrete....


Is also a way to convert CO2 from ocean water directly to methane or hydrogen, and the ocean is much better at collecting it than trying to capture out of the air.

James Lovelock proposed a network of plastic , freefloating , vertical tubes -200 meters long - set into the ocean. These would passively pump sea water up to the surface and fertilize algae blooms. Plankton would consume algae which would excrete as waste carbon , which would then settle down to the ocean floor.
Life began in Mother Ocean , maybe the sea holds the key to sustaining it.

and another way to incorporate the cycle.

they are using iron to break carbon coal, and trapping the CO2. You could then use the previous cycle to convert the CO2 to fuel.

and another use for the chalk from the first paper

Great way to use coal, to make hydrogen and nat gas with these projects
