This invention relates to a system for generating clean electrical energy by maximizing the utilization of seawater flow during tidal movements. The system comprises a C-shaped coastal marine dam open towards the shoreline, consisting of four walls (1, 2, 3, and 4). A fixed base (5) is installed between the two walls (2 and 3) farthest from the shore and includes two lateral sides, forming a narrow water passage (gate) (6) between them. The dam encloses a large area adjacent to the shore, preventing seawater from entering during high tide except through the narrow passage, thereby creating a highly concentrated water flow that can be harnessed for electricity generation. The system also includes two movable bases (13) mounted on the lateral sides of the fixed base, capable of moving vertically in response to the changing water levels during tides In order to move the giant turbine(14) in a vertical motion.. Each movable base(13) is connected to air tanks (13-2) positioned beneath the fixed base. A large circular turbine (14) is mounted on a shaft (15) supported by the two movable bases. Two large pulleys (17) are attached to both ends of the turbine shaft, transmitting rotational motion to gearboxes (19), which in turn drive electrical generators (21). During tidal movement, seawater flows exclusively through the gate (6), striking the turbine blades and causing the turbine (14) to rotate with high torque. This rotational energy is transmitted via the pulleys and gearboxes to the generators, which produce electrical energy. The vertical movement of the turbine (14) ensures that it is not fully submerged, so that seawater impacts only the blade edges rather than the central area, thereby maximizing the efficiency of energy extraction from the flow. Additionally, this invention combines high efficiency in clean energy production with reduced operational costs and offers a unique touristic and educational attraction. The coastal location and vertically adjustable turbine allow for the construction of viewing platforms or visitor walkways, making the site a distinctive destination for tourism and learning.
