One of these machines could sequester about 10 tons of Co2 per annum. (1) According to the linked article we have roughly 25 billion tons of Co2 emissions yearly. If we take 5k cities in the world (2), and each had just one machine you could cut emissions down to about 500k tons per year, that is a 1e6 factor magnitude difference. If each city had a single "farm" of 20 of these (they are 3x3x7 after all for roughly 400 m^3 of space) you'd be down to 25k tons of Co2 per year.

- kebman 7y agoI wonder how much CO² you could sequester from the atmosphere per year by removing just one cargo ship.
- IanCal 7y agoNone. You'd reduce emissions if it was not replaced by anything else and you don't look at the impact of what was being transported, but you'd not sequester any carbon.
- IanCal 7y agoHang on, if they sequester 10 tons and you build 5000 of them you would sequester 50,000 tons per year, not nearly 25 billion. 10 tons is in the region of what the global per capita emissions are so you're looking then at about 3+ billion needed.
