Provisional Patent Application Ocean Based Algae Biofuel Production System - R Tulip July 2009:
1. The Algae Production System is a photo-bioreactor floating in the ocean, made primarily of polymer fabrics and enclosed contents.
2. Algae production chamber shown at A and B is a continuous chamber floating at ocean surface. (A) indicates points of addition of inputs and (B) indicates output point for algated content.
3. Lower chamber (C) contains gas (eg air or CO2) which passes through one way valves (four vertical arrows (J) through polymer layer (I) into algae chamber A and B.
4. Polymer bag (D) contains fresh water, surrounding algae production chamber A-B, and connected to submarine bags E and F as shown at separate schematic drawing of top view.
5. Liquid source (K) and gas source (N) are pumped through inlet pipes (L) and (M) into submarine pumping chambers (E) and (F).
6. Rise and fall of bag D with wave causes chambers E and F to expand and contract, pumping liquid from bag E into chamber A and gas from bag F into chamber C.
7. Rigid base container G extends beneath and connects all bags E and F, such that wave energy transmitted from bag D expands and compresses bags E and F to provide pumping pressure rather than causing bags E and F to rise and fall with the swell or expand and shrink horizontally.
8. Barrier I between chambers C and A-B is reflective and insulated to maximise retention of sunlight and heat entering through transparent polymer layer (H) into upper chamber E and F.
9. Volume of gas in chamber C can be increased or decreased to regulate depth of entire system. When chamber C is full the system will float high, and when empty it will sink lower.
