NOVELTY - Apparatus comprises: (a) at least one first electrical conductor acting as a cathode and a second electrically conductive housing acting as an anode; (b) an electrical power source operably connected to the first conductor and the housing; and (c) a secondary tank operably connected to the first electrical conductor and the housing, so that the aqueous suspension flows from the flow path into the secondary tank for separation of at least one intracellular component from the ruptured algae cells in aqueous suspension.    USE - The apparatus is useful for: harvesting a mass of ruptured algae cells and debris from an aqueous suspension comprising algae cells; and harvesting at least one intracellular component from algae cells in aqueous suspension (all claimed), where the intracellular component is e.g. lipid, carbohydrate and protein and the cellular mass and debris is processed into a variety of products including biogas (e.g. methane and synthetic gas), liquid fuels (e.g. jet fuel and diesel), alcohols (e.g. ethanol and methanol), food, animal feed and fertilizer.    ADVANTAGE - The apparatus provides simple and efficient harvesting of intracellular components from algae, where intracellular components are used as a substitute for fossil oils and their derivatives in manufacturing of industrial products.    DETAILED DESCRIPTION - Apparatus comprises: (a) at least one first electrical conductor acting as a cathode and a second electrically conductive housing acting as an anode, where the first conductor is disposed within the housing, so that a space is defined between the exterior of the first conductor and an interior of the housing, providing a flow path for the aqueous suspension, and at least a portion of at least one surface of the first conductor and the housing is removed to create at least two spiral grooves separated by at least one land that reduces or prevents algae cell buildup on or around the first conductor and the housing; (b) an electrical power source operably connected to the first conductor and the housing for providing a pulsed electrical current that is applied between the first conductor, the housing and the aqueous suspension for rupturing the algae cells resulting in a mass of ruptured algae cells and debris, and release of intracellular components from the algae cells in the aqueous suspension; and (c) a secondary tank operably connected to the first electrical conductor and the housing, so that the aqueous suspension flows from the flow path into the secondary tank for separation of at least one intracellular component from the ruptured algae cells in aqueous suspension. INDEPENDENT CLAIMS are also included for:    (1) a method of harvesting at least one intracellular component from algae cells in aqueous suspension comprising: (d) providing the apparatus, where the apparatus further comprises an aqueous suspension comprising conductive minerals and algae cells, where the aqueous suspension is disposed in the flow path of the apparatus; (e) applying a sufficient amount of a pulsed electrical current to the first conductor, the housing and aqueous suspension for caused alternative expansion and contraction of the cell contents, thus rupturing the algae cells resulting in a mass of ruptured algae cells and debris, and release of intracellular components from the algae cells in the aqueous suspension; (f) flowing the aqueous suspension containing the mass of ruptured algae cells and debris, and released intracellular components to the secondary tank for separating the intracellular components from the biomass and aqueous suspension; and (g) separating the intracellular component from the mass of ruptured algae cells and debris and aqueous suspension; and    (2) a method of harvesting a mass of ruptured algae cells and debris from an aqueous suspension comprising algae cells comprising: (h) providing the apparatus, where the apparatus further comprises an element disposed in the secondary tank for producing microbubbles, an aqueous suspension comprising conductive minerals and algae cells, where the aqueous suspension is disposed in the flow path of the apparatus, and a pump disposed in the secondary tank for circulating the aqueous suspension; (i) applying a sufficient amount of a pulsed electrical current to the first conductor, the housing and aqueous suspension for rupturing the algae cells resulting in release of intracellular components from the ruptured algae cells, and a mass of ruptured algae cells and debris in the aqueous suspension; (j) flowing the aqueous suspension containing the released intracellular components, and mass of ruptured algae cells and debris to the secondary tank for separating the biomass from the released intracellular components and the aqueous suspension; (k) activating the pump and the element for producing microbubbles resulting in many microbubbles that attach to the released intracellular components and float upwards in the aqueous suspension, and sinking of the mass of ruptured algae cells and debris downwards in the aqueous suspension; and (l) separating the mass of ruptured algae cells and debris from the released intracellular components and aqueous suspension.
