Bioreactor and system for improved productivity of photosynthetic algae
First Claim
1. A bioreactor system for improved productivity of photosynthetic algae, comprising a tubular housing surrounding a tubular envelope located therein and defining a space therebetween, said housing and envelope being made of at least a translucent material, said housing and envelope having inlet and outlet ports providing access to said space and the interior of said envelope, and means for mixing an algae media disposed inside said envelope;
- said space containing a fluid having a refractive index selected with respect to a given geometrical relationship between said housing and envelope and said fluid is introducible into said space through the inlet and outlet ports; and
most solar radiation impinging on said housing will reach the algae media and the light concentration power of the bioreactor is set at a predetermined level.

Abstract
A bioreactor for improved productivity of photosynthetic algae includes a tubular housing surrounding a tubular envelope located therein. The housing and envelope define a space therebetween to be filled with fluid. The housing and envelope are made of at least a translucent material and have inlet and outlet ports providing access to the space and the interior of the envelope. A mixer for mixing algae media is disposed inside the envelope. There is also provided a bioreactive system, wherein the envelope contains a fluid of selective refractive index and wherein, for a given geometrical relationship between the housing and the envelope, the radiation concentration power is controlled by modifying the refractive index of the fluid.

14. A bioreactor system for improved productivity of photosynthetic algae, comprising:
-
a housing formed of a material selected from the group consisting of translucent and transparent materials; an envelope located in the housing such that a space is defined between the housing and the envelope, the envelope formed of a material selected from the group consisting of translucent and transparent materials; inlet and outlet ports provided in the housing and envelope, and providing access to the space and to an interior of the envelope; an algae media inside the envelope; a mixer for mixing the algae media; said space containing a fluid having a refractive index selected with respect to a given geometrical relationship between said housing and envelope and said fluid is introducible into said space through the inlet and outlet ports; and most solar radiation impinging on said housing will reach the algae media and the light concentration power of the bioreactor is set at a predetermined level. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
