Abstract

Systems and methods for hydroponically growing microorganisms within a self-contained air-supported structure, in which microorganisms are grown in an organic slurry, harvested, and processed to obtain and process and distribute molecules useful for biofuel or other purposes.

Claims

1. A system for hydroponically growing photosynthetic microorganisms comprising:

a climate controlled air-supported structure including a translucent membrane;

a plurality of open cradles placed generally horizontally within said structure;

wherein said plurality is capable of receiving a slurry comprising microorganisms in a liquid medium through an inlet end, and permitting harvest of said microorganisms through an outlet harvest end; and

and wherein each of said cradles in said plurality has a downward slope to permit said slurry to move from said inlet end to said outlet harvest end in a manner that permits growth of said microorganisms.

2. The system of claim 1 wherein carbon dioxide is distributed to at least one of said plurality of cradles within said structure.

3. The system of claim 1 further comprising a light source capable of radiating light from under said cradles to said microorganisms.

4. The system of claim 5 wherein said light source comprises a tube structure enclosing a plurality of light bulbs and affixed on said cradles'"'"' underside, and wherein said underside is translucent or transparent.

5. The system of claim 1 wherein said microorganisms are algae.

6. The system of claim 1 wherein said microorganisms are bacteria.

7. The system of claim 1 wherein said liquid medium comprises substances derived from farming excess, and water.

8. The system of claim 1 wherein said translucent membrane is an outer membrane, and said structure further comprises an inner membrane.

9. The system of claim 1 wherein each of said cradles has a downward slope of between about 1 and about 5 degrees.

10. A system for farming photosynthetic microorganisms comprising:

means for storing a liquid medium;

storing microorganisms in a second storage means;

means for mixing a predetermined quantity of said liquid medium with a predetermined quantity of microorganisms to form a slurry;

a self-contained growing enclosure, comprising;

a structure including a translucent membrane;

a racking system, comprising a plurality of racked, generally horizontal, open cradles, within said enclosure;

means for controlling temperature within said enclosure;

means for directing said slurry into of said cradles at an inlet end of said cradles;

means for distributing a predetermined quantity of carbon dioxide into said cradles;

means for permitting multiplication of said microorganisms;

means for providing e a continuous conditioned and filtered air flow across all of said cradles;

means for harvesting said microorganisms.

11. The system of claim 10 wherein said means for harvesting utilizes froth floating, flocculating, dissolved air floating, or centrifuging.

12. The system of claim 10 said means for permitting multiplication comprises means for radiating light from under said cradles to said microorganisms.

13. The system of claim 10 wherein said microorganisms are algae.

14. The method of claim 10 wherein said microorganisms are bacteria.

15. The system of claim 10 wherein said liquid medium comprises substances derived from farming excess and water.

16. The system of claim 10 wherein said system is automated.

17. The system of claim 10 wherein said structure is supported by airbeams.

18. The system of claim 10 wherein said structure is supported by air pressure.

19. The system of claim 10 wherein said structure is tension-supported.

20. The system of claim 10 wherein each of said cradles has a downward slope of between about 1 and about 5 degrees.
