They give the following numbers: 80 containers, 36000 tons of CO2/year, 90% efficiency. We also know that there's roughly 0.75g of CO2 in a m^3 of air. So we do some math, converting to a proper system of measurement and back to lalaland units using 907.2 kg in a US ton and 35.315 cubic feet in a m^3: 36000 [tons of CO2/year/80 containers] / 80 [containers] * 907.2 [kg/ton] * 1000 [grams/kg] / 0.75 [g/m^3] / 90% [efficiency] / (365 * 24 * 60) [minutes/year] * 35.315 [cubic feet/m^3] = 40636.4383562 [cubic feet / minute / container] So one of their containers filters about 40000 CFM at 90% efficiency. Was any of this helpful? Not at all. Just looking at tons of CO2 produced vs. captured would have given us the same picture, and that's the numbers we started with. > if 100 factories were built, each producing one unit per week That's a tiny amount at planet scale and also incredibly slow. Humanity builds around 150,000 cars every single day. Some factories crank out a thousand a day. And I'm going to go out on a limb and claim that a car is probably a more complex product.
