the easiest solution is growing dense vegetation including trees, then using that for things[0] or burying it until we have a better mitigation strategy for atmospheric carbon.

Another solution, and one that, if i weren't such a lazy, is ocean based carbon binding. You can run electricity directly through ocean water and precipitate the carbon out as calcium carbonate, which is both: useful to humans as is and after processing; and useful to the coral reefs and crustaceans/mollusks or whatever in the oceans.

If anyone wants to kick me about a million US dollars, i can make a POC on a used barge with solar panels and as much recycled material as possible, and have that just run off the coast of florida or something. I figure the total cost to get a barge is around a quarter million, all-in[1], the electronics and seawater stuff is about another $150-200 thousand, and the rest is mine for the idea and the lawyers' to get this approved and left alone to do the research.

[0] burning it for heat is fine, as the net CO2 levels will remain constant, but i mean things like houses and boardwalks and boats, furniture, and so on.

[1] could be more, now, the last time i was researching seaworthy barge costs it was between $100,000 and $200,000. I'm hoping there's someone that can donate the barge so i can make the rest more fit for purpose - redundancy, better solar, better mppt, better batteries, better materials for the electrodes (it takes platinum and titanium iirc, i haven't looked at my documents for a long while.)

The earth will recover. We may not, but earth will.
