NOVELTY - Device comprises water supply pipe (6), which is connected to water supply system (7). The water supply system provides energy to deep marine aquaculture microalgae. The device also includes an internal chamber provided with inflatable water suspension unit (1). Transparent hose inlet is connected to inflatable water suspension unit and power generation device (3) through glue pipe (2). The power generation device is used as collection bag (4) for microalgae. The water supply pipe passes through the gas chamber inflatable water suspension unit and enters into the transparent hose.    USE - Device for cultivation of microalgae (claimed).    ADVANTAGE - The device is easy to use, reliable and eco-friendly, and enables to cultivate microalgae in a simple manner.    DETAILED DESCRIPTION - Device comprises water supply pipe, which is connected to water supply system. The water supply system provides energy to deep marine aquaculture microalgae. The device also includes an internal chamber provided with inflatable water suspension unit. Transparent hose inlet is connected to inflatable water suspension unit and power generation device through glue pipe. The power generation device is used as collection bag for microalgae. The water supply pipe passes through the gas chamber inflatable water suspension unit and enters into the transparent hose. The microalgae are cultured inside the transparent hose. Power generation device is provided hollow gas chamber and water chamber from outside to inside. The water chamber equipped with a turbine generator (22). The collection bag is a network-shaped hollow structure. Wave motion enters through water supply device and then reach to transparent hose. Effect of wave movements in deep water drives turbine generator. Discharged product is collected from collection bag.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of device.
