advantages and disadvantages
5.1. Tidal turbines plants
This idea emerged thanks to the electric motor generator propellers for underwater vehicles. Instead of using electricity to initiate movement of the propeller and drive the vehicle, the water flow turns the propellers generating electricity. It works the same way that wind farms and costs the same as them. This generation has many advantages over the other methods.
5.2. Barriers plants tidal
They are barriers constructed across an estuary or bay that must support a range of special tide. The range should exceed 5 meters to be useful. The barriers has gates that open the way to the water. The gates are closed when the tide has stopped rising, trapping water in the basin. As the tide recedes outside the barrier, the barrier gates containing turbines are opened and the difference of water levels inside and outside the barrier caused to flow through these gates, powering the turbines and generating energy.
