Claim 14:
15. A photobioreactor comprising:
a containment structure arranged to contain a liquid culture medium for cultivating seaweed, the containment structure including at least one sidewall extending vertically between a top and bottom section, the bottom section including an effluent portal arranged to allow extraction of cultivated seaweed;
a spiral liner positioned adjacent to an inside surface of the at least one sidewall and being in contact with the liquid culture medium;
a recirculator including an inlet adjacent the bottom section and outlet adjacent the top section, the recirculator including a medium return system forming a channel within the containment structure between the inlet and outlet, the recirculator including a pump, located within the channel of the recirculator, configured to continuously receive a portion of the liquid culture medium via the inlet from the bottom section and output the portion of the liquid culture medium via the outlet to the top section;
an array of sensors arranged to monitor at least one environmental condition within the photobioreactor;
an array of light emitters arranged along a surface of the spiral liner;
a plurality of flow generators, positioned within the containment structure in a spiral configuration between the top section and bottom section, arranged to direct a flow of the liquid culture medium from the top section toward the bottom section of the containment structure along a downward spiral path; and
a controller arranged to receive sensor data from at least one sensor of the array of sensors and, in response to the sensor data, adjust the at least one environmental condition by at least one of adjusting a flow rate of one or more of the plurality of flow generators and adjusting a light intensity of one or more light emitters of the array of light emitters.
