FAST TRACK  It takes thousands of years for this mineral to form naturally. Now researchers have found a way to make magnesite, or magnesium carbonate, in the lab in just a few months.
 

Scientists are one step closer to a long-sought way to store carbon dioxide in rocks.

A new technique speeds up the formation of a mineral called magnesite that, in nature, captures and stores large amounts of the greenhouse gas CO2. And the process can be done at room temperature in the lab, researchers reported August 14 at the Goldschmidt geochemistry conference, held in Boston. If the mineral can be produced in large quantities, the method could one day help fight climate change.

Ok,so what do they do with the rocks? Even rocks wear down and turn to dust,you know.

LMAO.....

Hmmm less see.   Globull warming alarmist claim that humans have contributed about 30-40 billion pounds of excess CO2.

Based on a Molar Conversion of 1 mole CO2= 44.3 gms. gas/mole and 1 Mole of MgCO3 =84.3 gms. solid/mole

MgCO3 + CO2 + H2O ->. Mg(HCO3)2

Looks like a straight one to one molar conversion.  Therefore...

To just remove a billion pounds of CO2 (Say 2%), it would take (and cost) the manufacture, and distribution like a desiccant of about 1.9 billion pounds of this material.  Which furthermore, might not be 100% efficient since only the surface of the mineral would be effective 

My guess....Someone didn't think this through.

I believe nature has already generously supplied us with that process.

It is called photosynthesis and is utilized by the trillions of plants existing on this planet.

The material acts like a catalyst, and can be regenerated.

The material acts like a catalyst, and can be regenerated.

I worked in the petrochemical industry 30 years.   

Do you realize

(1) the cost and fossil fuel usage to regenerate this kind of catalyst?  One's I  remember can get over 1000 F.
(2) The cost and Real estate needs of placement of vessels regenerate spent materials in this volume? Not to mention staging, shipping, and manpower.
(3) And then there is the issue of the volume ?  Logistical near impossibility. I'm skeptical that it would even put a dent in arthopogenic CO2.

Interested to hear in any way this might be a feasible technology.  At my vantage point, there isn't any.
