TECHNOLOGY FOCUS - BIOLOGY - Preferred System : The biomass converters include a culture medium containing phytoplanktonic and/or zooplanktonic microorganisms, the phytoplankton preferably being chosen from Duanliella salina, Tetraselmis sp. Isochrysis galbana, Pavlova lutheri, Rhodomonas salina, Phaedoactylum tricornutum, Thalassiosira weissflogii and Chaetoceros socialis.    TECHNOLOGY FOCUS - ENVIRONMENT - The biomass converters have a round concentric single chamber, a round concentric dual chamber or a round composite design, containing vertical tubes arranged around a central light shaft. The converters are spatially arranged to form a honeycomb or modular structure and comprise control tubes emitting artificial light, ion dispersers (36), electromagnetic flow adjustment valves (19), electromagnetic biomass extraction valves (20), control sensors (21) for the culture medium, hydrogen extraction valves (23), entrances for daylight (2a, 2b), lamps for generating artificial light (24), rotary cleaning systems (28), carbon dioxide injection valves (29) arranged in a helical configuration, turbulence generating valves (30) arranged in a helical configuration, and systems (31) for removing and controlling the lamps. The feed/mixer tanks are cylindrical and/or polyhedral/shaped and have an internal volume of 3-14 m3. The culture medium is exposed to an electrical field of 300-600 (400-500) V/m and a magnetic field of 0.1-1.0 (0.25-0.75) T.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Biomass is centrifuged and dried after being removed from the culture medium, silicates and cellulose are separated using apolar solvents and the cells in the culture medium are ruptured using ultrasonic energy, polytronic combustion, microwaves and/or heating to 200 degrees C. Hydrocarbons are oxidized by (in)direct combustion during the drying step. Lipids from the centrifuge step can be transesterified and hydrocarbons from this step can be distilled using a hydrocracking catalyst to obtain products such as kerosene, benzene, biodiesel, naphtha and glycerine. Sugars from the centrifuge step are subjected to a molecular rupture step to form ethanol.    TECHNOLOGY FOCUS - POLYMERS - The particle filters are made from cellulose, glass and/or cellulose acetate fiber. The feed/mixer tanks and compensation tanks are made from a transparent material, preferably PVC, polycarbonate and/or methacrylate.
