NOVELTY - The apparatus comprises an algae bioreactor (12), a biomass extraction system (13) connected to the output of the algae bioreactor, where the bioreactor supplies water, algae, biomass and dissolved organic matter to the extraction system, and a microbial generator (18) such as fuel cell connected to the output of the extraction system. The generator produces electricity as an end product. The bioreactor is a device for holding water, algae, nutrients and carbon dioxide to provide materials required for the growth of algae in contact with adequate light to stimulate the growth of the algae.    USE - The apparatus is useful for converting aquatic biomass into fuels and electricity, where the biomass product is useful for energy, agriculture, pharmaceuticals or food applications.    ADVANTAGE - The apparatus ensures efficient and cost-effective conversion of aquatic biomass to fuels and electricity, and can smooth out the total power flow off of the production site so that it is a more consistent and predictable source of renewable electricity.    DETAILED DESCRIPTION - The apparatus comprises an algae bioreactor (12), a biomass extraction system (13) connected to the output of the algae bioreactor, where the bioreactor supplies water, algae, biomass and dissolved organic matter to the extraction system, and a microbial generator (18) such as fuel cell connected to the output of the extraction system. The generator produces electricity as an end product. The bioreactor is a device for holding water, algae, nutrients and carbon dioxide to provide materials required for the growth of algae in contact with adequate light to stimulate the growth of the algae. The biomass extraction system comprises a dewatering device (14) for receiving water, algae and dissolved organic material from the bioreactor, and a biomass dryer (18) connected to an output of the dewatering device for receiving wet algae from the dewatering device and producing dry algae product at the output. A byproduct of the microbial generator is water, carbon dioxide and nutrients for algae. The generator includes a unit for feeding back the water, carbon dioxide and nutrients to the algae bioreactor to supplement an initial charge using a source of sunlight, algae carbon dioxide and water. A unit is arranged for transmitting electricity from the microbial generator to the dewatering device and to the biomass dryer. The microbial fuel cell comprises two chambers separated by a selectively permeable membrane. A first side of the membrane is an anode and the second side of the membrane is a cathode. The source of nutrients, carbon dioxide and water is an effluent from a power plant, an animal farm or fish farm, and a waste treatment facility. The connection of the bioreactor to the biomass extraction system is provided by a combination of pumps and gravity flow. The bioreactor comprises a raceway, and an open body of water. The bioreactor is covered by a solar panel that passes visible light through the panel and uses non-visible light to generate electricity. The apparatus is co-located with an intermittent external source of electricity, and the power generated by the apparatus and its algae are used to augment the total electricity provided by filling during the periods of low power production from the intermittent source. An INDEPENDENT CLAIM is included for a method for continuous culturing of microalgae to produce electricity and biomass.
