Patent ID: 8809041

Claim:
A photo bioreactor ( 1 ) configured to comprise an aqueous liquid ( 20 ) comprising a photosynthetic culture ( 21 ), said photo bioreactor comprising (a) a plurality of light distributors ( 30 ), which light distributors ( 30 ) have (i) surfaces ( 31 ) configured to receive light ( 40 ), and (ii) tapered surfaces ( 32 ) configured to emit at least part of the received light ( 40 ), wherein at least part of the tapered surfaces ( 32 ) are submersible in the aqueous liquid ( 20 ), and (b) a construction ( 300 ) comprising the plurality of the light distributors ( 30 ), which construction is corrugated, and the light distributors ( 30 ) are corrugations ( 308 ), and (c) a body ( 60 ) comprising a plurality of cavities ( 61 ) having tapered surfaces ( 62 ), with the light distributors ( 30 ) and the body ( 60 ) configured so that: (i) the light distributors ( 30 ) are at least partly configured in the cavities ( 61 ), (ii) the plurality of cavities ( 61 ) form a corrugated counter construction ( 600 ), (iii) the tapered surfaces ( 62 ) of the cavities ( 61 ) are at a distance (d 2 ) from the tapered surfaces ( 32 ) of the light distributors ( 30 ), creating a channels ( 64 ) between the light distributors and the counter construction ( 600 ) enabling a uniform flow of liquid ( 20 ) between the fluidically connected cavities ( 61 ); and (iv) the construction ( 300 ) and the body ( 60 ) are a single reactor body ( 360 ).
