1. A method for generating turbulent algae cultivation fluid flow in an open-air raceway algae cultivation pond, the method comprising:
- initiating a circulation of fluid in the open-air raceway algae cultivation pond via at least one liquid jet, the circulation of fluid generating a velocity of the turbulent algae cultivation fluid flow of at least ten centimeters per second in the open-air raceway algae cultivation pond; and
providing a head to the at least one liquid jet that overcomes a head loss associated with the velocity of the turbulent algae cultivation fluid flow of at least ten centimeters per second in the open-air raceway algae cultivation pond, wherein each liquid jet is connected to at least one submerged nozzle, the nozzle aligned parallel to the turbulent algae cultivation fluid flow, the nozzle increasingly constricting in diameter as it progresses from inflow to outflow, the nozzle positioned at or near a middle of the open-air raceway algae cultivation pond, and the liquid jet from the nozzle contributing to the fluid flow throughout a majority of the open-air raceway algae cultivation pond.
