[snip] I note that they don't mention where the energy is coming from to heat the CaCO3 to split it into CaO and CO2 again. This would need to be derived from either a clean nuclear source (CF) or Solar thermal. Given placement of the collector in a desert, the latter would seem most appropriate, at least until CF matures, however I doubt they included that in their cost estimate.
BTW vehicles could probably be fitted with Ca(OH)2 or CaO based scrubbers in the exhaust (analogous to catalytic converters). These could be exchanged at gas stations when filling up.
