1. A system capable of directly removing CO2 from a planet'"'"'s atmosphere by extracting and collecting carbon dioxide from the atmosphere, such that when a plurality of other such systems strategically placed across the globe, and coordinated so as to collectively function for extracting CO2 from the atmosphere is capable of reducing the ambient concentration of CO2 in the planet'"'"'s atmosphere from what it may otherwise be, the plurality of systems being in locations geographically dispersed around the planet with each capable of removing carbon dioxide from the planet'"'"'s atmosphere by extracting and collecting carbon dioxide from the atmosphere, each system comprises an air contactor, wherein the air contactor comprises an amine absorbent on a solid surface, the amine being capable of absorbing carbon dioxide from the atmosphere, and of being regenerated by having the carbon dioxide removed therefrom using process heat steam;

  • a regenerator wherein the amine absorbent of the air contactor is regenerated;

    a fluid flow connector extending from the regenerator to a source of low temperature steam, at a temperature of less than about 120°

    C., the source of process heat steam being the steam exhaust from a steam-operated electric generator, the steam for operating the steam-operated electric generator being heated from a primary process using a primary energy source, for extracting and collecting carbon dioxide from the sorbent medium and regenerating the sorbent medium; and

    a location for at least one of storage and generation of a renewable carbon fuel, so that the plurality of systems together can effectively extract carbon dioxide from the atmosphere in an economically efficient manner.
