There are hard limits on recapture efficiency. The only way to make it remove more than it creates is to use energy like geothermal. Even then, the production of a carbon capture facility generates enough emissions that it would take years of constantly running, and you’d only ever reach it if you’re using 100% clean energy to power it.
We have fully renewable powered carbon capture facilities active right now. The manufacturing will take 2+ decades to pay off in captured carbon, and it would take 450,000 of them to capture 1% of carbon. It’s not a viable path. Period.
And it’s perfectly normal for technology to advance and become more effective and efficient over time.

So you build it like a Walmart? 90 percent of the square footage is ~~parking~~ solar?

Grind up basalt slightly more than we normally do. Spread it out.
It’s exothermic.
Rate limited, but more than enough to undo the damage if we stop digging up 95% of fossil fuels.
