This one machine in Germany is already making the equivalent of ~15 great pyramids per year, by tons of material moved:

Carbon capture is difficult currently, but we'd have to problem dispensing with this amount of material per year on a global scale.

- dash2 3y agoBut the point of the machine was to move the carbon after it's been produced. I agree there's a separate question, how much air do we need to suck through carbon extraction machines.
