The best things for carbon capture are plants. Obviously it can be done artificially, but the cost in energy is astonishing.
In theory, we could build a nuke in 5 years. The trick is to isolate on one basic design and replicate, perhaps the SMRs may come back, but I doubt it. Each nuke is unique, or almost that. Anyway, it's not going to happen after two more reactors come on line later this year and next, that's it for the US.
Each large aircraft carrier contains two nuclear power reactors. We park them at Norfolk and San Diego out in the harbor and no one blinks an eye.
