@3ddave that's what I was hoping for. I needed to bounce this off of people with expertise to test the logic.
So unsound mechanism and not enough energy in the world to do it. I actually thought it was possible. At least now I can stop.
@miningman yes sounds like I've got a good source of MgO near Radium. I've read a bit about that project.
Carbon removal to correct the excess in the atmosphere is going to be a difficult sale. I seems like governments are providing incentives and directives to reduce CO2 emissions. It's going...
@mintjulep yes I agree. I question the neutral philosophy of carbon fuel production. Sequestration of O2 in the CO2 isn't the correct solution. We aren't even addressing the O2 in H2O from combustion. Who would have thought that we could influence the amount of CO2 and O2 in our bubble?
Density MgO 3.58
Density C 3.52
Kind of close but might be enough.
Energy can be solar, wind, geothermal, hydro, tidal, perhaps nuclear.
I don't think we can afford cooling. Don't want to lose energy in the MgCO3⇌CO2+MgO reaction. Want to recover energy from 2Mg+CO2⇌2MgO+C for electrolysis of...
Q - kiln MgCO3⇌MgO+CO2
R - pure CO2 tank
J - Molten MgO
K - carbon anode
L - molten metal cathode
O - CO2 injection site
M - carbon to be submerged H2O
@3ddave. Thanks for the math.
2Mg+CO2⇌2MgO+C
441.5 x 48.61/12 = 1800 GT Mg
I'm using tons here.
I need about 570000 tons of Mg assuming that a lb of Mg takes 5 min to convert to MgO on pure CO2.
About.04 grams of Mg per person.
Or 950000 tons of MgO.
About .06 grams MgO per person.
The Mg is...
