Claim 0:
1. An algae cultivation system, comprising:
an algae cultivation container comprising algae in a cultivation medium;
at least one light source configured to illuminate the interior of the container;
at least one sensor, to measure at least one parameter within the container;
at least one first source, said at least one first source including air and/or nitrogen gas;
at least one second source, said at least one second source including gas with over 30% CO2 concentration for biological consumption by the algae;
at least one first sparger, to distribute a first fluid from the at least one first source into the container at a first operating flow rate;
at least one second sparger, to distribute a second fluid from the at least one second source into the container at a second operating flow rate based on the at least one measured parameter;
wherein the at least one first sparger has a nozzle diameter that is larger than 1 millimeter, and the at least one second sparger has a nozzle diameter that is smaller than 1 millimeter; and
at least one controller configured to control the first operating flow rate, the second operating flow rate and the at least one light source,
wherein the first fluid comprises air and/or nitrogen gas bubbles, the first operating flow rate is adapted to allow turbulent mixing of the algae and to yield illumination cycles for the algae in the cultivation container, and
wherein the second fluid comprises gas bubbles with over 30% CO2 concentration for biological consumption by the algae, and the second operating flow rate is adapted to allow assimilation of materials by the algae in the cultivation container from the second fluid; and
wherein both fluids are introduced at a bottom of the cultivation container and rise through the cultivation medium to a top of the cultivation container.
