Claim 10:
11. A method for cultivating a biomass using a photobioreactor comprising:
containing a liquid culture medium for cultivating seaweed using a containment structure, 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;
positioning a spiral liner adjacent to an inside surface of the at least one sidewall and in contact with the liquid culture medium;
continuously receiving a portion of the liquid culture medium from the bottom section via a recirculator inlet of a recirculator, the recirculator including a medium return system forming a channel within the containment structure between the recirculator inlet arranged adjacent the bottom section and a recirculator outlet adjacent the top section;
outputting, from a pump located within the channel of the recirculator, the portion of the liquid culture medium via the recirculator outlet to the top section;
monitoring at least one environmental condition within the photobioreactor;
positioning an array of light emitters along a surface of the spiral liner;
positioning a plurality of flow generators within the containment structure in a spiral configuration between the top section and bottom section; and
directing, by the plurality of flow generators, a flow of the liquid culture medium from the top section toward the bottom section of the containment structure along a downward spiral path.
