Okay. They are not exclusive. But I can care a bit more about things affecting humans' future than things affecting someone's earnings. Not that I really care so much about humans (we will get what we deserve and that is it, for me). Back to my question. A small hint: nowhere on this Carbon Business website have I seen what they do with captured CO2 (I admit, I did not spent too long looking for it). I assume that if pilot installation (let's call it Pilot) captured a ton per day, they promptly released it straight away. Later on, the upgraded Pilot is said to make a barrel of "fuel" (what kind of "fuel"? anybody knows? is it described in Cell article?), but this too is going back to the air as soon as the quality is good enough to feed an engine. Looking at the picture of Pilot, I think the materials used might be equivalent of 2 m^3 (cubic meters) of steel, which gives weight of about 15 tons (15000kg). A world consumes 100 mln barrels a day, means there is a need for 100 mln Pilots. This means 1500 mln tons of steel. Global steel production was 1691 mln tons in 2017. A person quoted in The Atlantic article hoped we could "stabilise climate without changing our lifestyles", but this quick BOTEC tells me "I am afraid this is not going to be so". Even if 100mln Pilots get built (doubtful; how long will it take, anyway), and assuming Global Warming is driven by CO2 increase, those units merely stop increase of one greenhouse gas, at a huge costs, and then the change will go on anyway. Can a business be made of this? Sure. I do not blame them, I just refuse to be enthusiastic.
