This invention relates to a system for generating clean electrical energy by maximizing the utilization of seawater flow during tidal movements.

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.
