1. A system for production of microorganisms comprising:

  • a light absorbing droplet unit, a holding tank, a pump, a flat panel unit and a second pump,where the light absorbing droplet unit comprises a chamber, a nozzle, and a lighting apparatus, where the chamber comprises four walls, where the walls are transparent, where the nozzle is oriented to spray within the chamber, where the nozzle is fluidly connected to the holding tank, where the lighting apparatus emits light into the chamber through one or more walls of the chamber,where the lighting apparatus comprises a plurality of light emitting diodes, where at least one of the plurality of light emitting diodes emits light at different wavelengths than another of the plurality of light emitting diodes,where the holding tank comprises water, where microorganisms are suspended within the water, where the water comprises diffused carbon dioxide and nutrients, where the water is forced from the holding tank through the nozzle by the pump thereby creating a spray of water within the chamber,where the flat panel unit comprises two flat plates and a plurality of bafflers, where the two flat plates are transparent, where the bafflers are secured between the two flat plates to create channels, where the flat panel unit is fluidly connected to the holding tank, where the second pump forces water from the holding tank through the channels of the flat panel unit.
