Don't know, seems like a good explanation. We have a number of machines that can take CO2 out, the "enough machines" is the problem.

- they either require space (forests or whatever)

- are hard to produce in sufficient numbers (materials, production capabilities)

- are expensive to run (like energy input, maintenance), in particular don't generate new red balls while removing them.

- disposal cost (where the machine becomes the carbon, like trees, cutting them down and doing something with that)

Once we got it out, on a "pile of carbon", the problem becomes much easier.
