Abstract: Carbon dioxide containing gas is collected from a point source or atmosphere and is dried, treated, and compressed. The compressed gas is fed into an algae reactor which maintains optimal conditions for algae growth. The algae grows until it reaches sufficient density to be harvested. The harvested algae is processed and packaged for sale. Additionally, revenues may be earned by quantifying the amount of CO2 captured and sequestered by the algae and determining the carbon credit equivalent value. Byproducts may additionally be sold in addition to equipment sales and licensing.

Abstract: A photobioreactor (100) for use in treating polluted air and producing biomass may comprise, at least in part, a generally vertical tube or fluidic pathway (102), a generally vertical helical tube or fluidic pathway (104) having a light source (106) partially positioned within the helical fluidic pathway (104), a head cap assembly (108), and a base assembly (110). In one illustrative example, the light source (106) may be a light emitting diode (LED) or a plurality of light emitting diodes (LEDs). By one approach, a gas diffusion apparatus (112) is located at the base assembly (110) adjacent the generally vertical fluidic pathway (102).
