How does the 242 kJ/mol to extract carbon dioxide from seawater compare to the air technique? (The article in the OP gives us no good way to tell...)

Also, I think that while there's much more carbon in seawater than air per unit volume, there's actually more CO2 in air when you look on a ppm basis. I'm not sure which metric would more relevant here...

could coal plants use this process?? Angry Dragon Oct 2012 #1
There wouldn't be much point ... VMA131Marine Oct 2012 #3
What I meant to capture the Co2 that coal plants spew out Angry Dragon Oct 2012 #4
Co2 is fungible ToxMarz Oct 2012 #5
You could. Some algae-to-biodiesel proposals suggest coal plants as a CO2 source NickB79 Oct 2012 #14
That would be as silly as diluting gasoline with alcohol. sofa king Oct 2012 #16

But here is the rub NoOneMan Nov 2012 #23
So since it won't pay of instantly, we should just keep burning stuff like always? jeff47 Nov 2012 #24
Keep burning stuff like always opposed to burning more stuff like always? NoOneMan Nov 2012 #25

Don't know the energy requirements of the air technique either Bosonic Nov 2012 #20
