I didn't want to accuse you of something like "not being an engineer" (which is perfectly fin as long as you're not working in digital marketing :) ), i'm sorry, it was poorly worded.

I've read the paper, it is very interesting, it does not talk about machine pumping carbon out of the atmosphere however (the figure appeared low, now i know why). But yeah, DAC might be a solution. I'll rather take the IEA rapport on this [0].

Removing CO2 from the atmosphere and removing carbon is not the same thing. You then need to either seal the CO2, or transform it ( in a power-to-gas station? ). Also their base case of 15% capex/year can go outside see if i'm there.
