Carbon filters? part soloution of global warming?

[athrax]

When air goes through a carbon filter it separates the carbon and turns it into water and lithium carbonate. Could the lithium carbonate be sold and that money used to buy parts for hydro electricity plants that use the water, or the water be used for drinking as it is already pure?

CO2 scrubbers generally use Calcium hydroxide - Lithium is a bit pricey.
They do make water but it's contaminated with NaOH (at least in diving CO2 scrubbers) so you wouldn't want to drink it.

Anyway - the process of making the absorbent (Ca(OH)2 or LiOH) is incredibly energy intensive - so not a solution to atmospheric CO2.
