Anyone who understands the concentration of CO2 in the air knows that these things are nothing but a PR stunt. You’re not going to pull enough out of the air to have any meaningful contribution; there’s just not a lot there to pull out. For all the harm it’s causing, CO2 makes up a tiny part of air composition, only about 0.04%.
These things are built for idiots who think the solution is as simple as “just run the air through a filter” and don’t grasp how much air there actually is, and how little there is to pull out.
That’s what the article is about. It also goes into biomass energy land use and the unknown effectiveness of grinding up rocks + laying them on farmland
