A new carbon capture plant will pull 36k tons of CO2 from the air each year
I have no faith in machines that suck the atmosphere through a straw.  The thermodynamics and fluid dynamics just don&#x27;t pencil out.  We need to remove something like 3.5 Tt of CO2, so 3.5 Kt is nothing.  Our only hope in this regard is solar&#x2F;uv-powered systems, mainly biological, for example algaes in pelagic waters (that grow and then die and sink to the bottom of the ocean).  These systems aren&#x27;t trivial to build either.<p>For other GHG and pollutants there are uv-powered systems like TiO2, olivine etc, though there are also limits to how much they can do.<p>Basically we have to &quot;mash our hand on the keyboard&quot;, i.e. try to do them all, but I can&#x27;t see machines like these making any meaningful contribution.<p>Note: I&#x27;m working on methane destruction straight in the atmosphere, so I&#x27;m putting my money (and my time) where my commenting is.
