The ERC technology is all about capturing and converting CO2 from major sources like Coal combustion, Cement manufacturing, Steel manufacturing, and is not designed or intended to replace nuclear power. Nuclear power does not produce CO2, but is very costly to permit and build, has political issues, and has safety issues in current designs and fuels, and has radioactive waste disposal issues. Coal is cheap, but has mercury, sulfur dioxide (acid rain) and CO2 emissions problems and solid waste problems (radioactive and toxic metals ash disposal problems).
One of the reasons I think Larry went after LaFarge CO2 emissions to start off is the Cement manufacturing has no nuclear or solar options with zero CO2 emissions!!! There is no solar option for making cement, it is made by removing CO2 from limestone, to make lime, cement which is needed to make concrete, for roads, buildings, dams.....!!!
