Abstract: Algae production systems and associated methods are disclosed herein. In one embodiment, for example, an algae production system can include a plurality of elongated growth receptacles arranged in a desired configuration at a work site. The growth receptacles have a generally non-circular cross-sectional profile and are configured to hold an algae culture, and wherein the individual growth receptacles have a generally non-circular cross-sectional profile. The system can also include a carbon dioxide (CO2) subsystem configured to supply provide CO2-enriched air to the growth receptacles, a fresh medium subsystem configured to supply a fertility solution to the growth receptacles, and a harvesting subsystem.
