System and method for removing carbon dioxide from an atmosphere and global thermostat using the same
First Claim
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.

Abstract
A system for removing carbon dioxide from an atmosphere to reduce global warming including an air extraction system that collects carbon dioxide from the atmosphere through a medium and removes carbon dioxide from the medium; a sequestration system that isolates the removed carbon dioxide to a location for at least one of storage and generation of a renewable carbon fuel; and one or more power supplying units that supply heat to the air extraction system to remove the carbon dioxide from the medium, at least one of the one or more power supplying units being a fossil fuel plant.

10. A worldwide system for directly removing carbon dioxide from the atmosphere to at least reduce the rate of increase of carbon dioxide in the atmosphere of the Earth, comprising a plurality of individual systems located around the planet, each of which is capable of reducing the amount of carbon dioxide in the planet'"'"'s atmosphere by extracting carbon dioxide from the atmosphere, each individual system comprises an air contactor comprising an amine supported on a solid substrate and capable of absorbing CO2, the amine being supported on a solid surface;
- so as to be exposed to the open air;
a regenerator for the CO2-containing air contactor;
a source of process heat steam and a flow connector for passing the process heat steam at a temperature of less than about 120°
C. from the source of process heat to the regenerator for capturing carbon dioxide from, and regenerating, the medium, and a fluid flow connector to pass the CO2 from the regenerator to a storage location, so that the plurality of systems together can effectively extract carbon dioxide from the atmosphere at a rate that at least reduces the rate at which carbon dioxide concentration is increasing in the atmosphere.
