It takes orders of magnitude more power to capture the carbon from the atmosphere than was gained putting it there in the first place.
It requires sucking in and processing inconceivable quantities of air requiring inconceivable amounts of land for the facilities, because the carbon we need to capture has been released and distributed into the earths atmosphere.
The engineering required to scale out any existing or envisioned technology to put a meaningful dent just on our yearly emissions is more than simply replacing the worlds energy production with zero emissions generation and storage.
Whether you can conceive the amounts of air and energy it requires is not really scientific arguments.
A scientific argument transcends personal beliefs.
You might believe that such a feat is inconceivable, but lets agree not to pollute the language any more by using the word "scientific" when we mean "believe".
