1. A system for capturing carbon in a carbon-poor media to create a carbon-enriched media thereof, for assimilation of the carbon captured by the enriched media into an algae biomass, the system comprising:

  • a reactor for growing algae biomass in the media, wherein the reactor has an input port and an output port;

    an absorber having a plurality of panels, wherein each panel has a surface area, and wherein the absorber has a first input port, a second input port, a first output port and a second output port;

    a source of combustion gases with a conduit for directing the combustion gases into the absorber through the first input port of the absorber;

    a pump for establishing a volumetric flow rate of carbon-poor media from the output port of the reactor and into the second input port of the absorber, wherein the carbon-poor growth media is presented on panel surface areas in the absorber for a counter current flow interaction with the combustion gases to create the carbon-enriched growth media for discharge from the first output port of the absorber and into the reactor through the input port of the reactor;

    a first sensor for measuring a first carbon concentration level, C1(measured), in the reactor at the output port of the reactor;

    a second sensor for measuring a second carbon concentration level, C2(measured), of media discharged from the first output port of the absorber; and

    a controller for operating the pump with input from the first and second sensors to establish an optimized assimilation of captured carbon from the carbon-enriched growth media into the algae biomass in the reactor.
