1. 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 (d2) 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).
