A photobioreactor (PBR) is a device that can contain and grow algae without the need for sunlight or sugars (required by ponds or fermen- ters, respectively). Los Alamos chemical engineer Munehiro Teshima designed and built this unique PBR to achieve exquisite control over gas flows and other factors such as temperature, illumination, alkalin- ity, agitation, and cell density. The reactor uses sophisticated sampling robots to take measurements and make adjustments in order to main- tain ideal growth conditions.
