So it would be a great thing to get the carbon back into the soil... but not by using ceramics or sth like that... let the plants do the job :-) Some farmers have realized that they heve heaps of benefits from mulch-till and no-till. Now the politicians and kyoto activists should realize that, too! the problem is, that the six foot deep black dirt was black because of the ORGANIC carbon stored in there. a lot of it is now gone to the atmosphere as well due to, as you stated correctly, lots of deep plowing which is absolutely senseless.

It can be seen as a black flash on the surface of a sodium based glaze. In Ceramics, we call it Carbon Trapping, and folks have been doing it for at least twenty years. It seems that carbon sequestration hasn't been thought through thouroughly to me. WHere we need the carbon is in our farm land. THe great plains used to be six foot deep black dirt from years and years of buildup of carbon from prairie plants and animals and wildfires piling up there. now the dirt is no longer black, but gray or red, due to lots of plowing and erosion of the lighter particles, and the earth color remains. Healthy soil is black, and black predominantly comes from carbon. If carbon could be collected in solid form or liquid form and plowed into our fields, or applied to our fields, wouldn't that make a prolific soil base? no need for petrochemical fertilizer to be added on, just use the waste carbon from everytshing else. Burning biofuels with even miniimal carbon sequestration logically leads to a net loss of carbon year to year, cycle to cycle. Of course wind into compressed air sounds fabulous too.

How much wind energy would be needed to pump the CO2 into the ground? Should I read the worst case added fuel need as 40% of the amount of coal energy that goes into generating electricity? I'm not sure what the efficiency of a coal-fired power plant is, but say it is around 40% which is probably close to where we are today. Would that mean that for an 800 MW plant you would need to provide up to 800 MW of wind energy (40% of the fuel needed to generate 800 MW) to pump the CO2 into the ground? Or in other words. Skip the coal plant and just use wind? Sooo… How much wind energy would be needed to pump the CO2 into the ground?
