TIDAL POWER

INTRODUCTION

The tidal energy is due to the forces of gravitational attraction between the moon, Earth and the Sun. The

tidal energy pathway is to harness the tides, the difference in average height of the seas as the relative

positions of Earth and the Moon and resulting from the gravitational attraction of the latter and the sun onthe masses water of the seas. This difference in heights can be harnessed to provide moving parts to the

natural movement of ascent or descent of the water, along with mechanisms for channeling and deposit, to

get moving on an axis. Through its link to an alternator system can be used to generate electricity, thus

transforming tidal energy into electrical energy, AND energy more useful and usable. It is a type of clean

renewable energy.

The tidal energy has the quality to be renewable, while the primary energy source is not exhausted by their 

exploitation, and it is clear, since in the energy transformation does not produce polluting byproducts

gaseous, liquid or solid. However, the relationship between the amount of energy that can be obtained with

the means and the current economic and environmental cost of installing the devices for its process have

prevented a remarkable proliferation of this kind of energy.

The tidal energy is converted into electricity in the so-called tidal power, which act as a reservoir of 

traditional river. The tank is filled with the tide and the water is retained until low tide to be released later 

through a network of narrow channels, increasing the pressure until the turbines that generate electricity.

However, their high cost of maintaining curbs their proliferation.

The ideal place to install a central is a tidal estuary, a bay or estuary where sea water enters.

The construction of a wave is only possible in places with a difference of at least 5 meters between high

and low tide.

The water, while passing through the canal cargo into the sea, drives the propeller of the turbine and the

latter, at the turn, moves a generator that produces electricity.

HOW IT WORKS

When the tide rises, the gates of the dam are opened and water enters the reservoir.

When you reach the level of water in the reservoir at its peak closing the gates.

During low tide the water level drops below the level of the reservoir.

When the difference between the level of the reservoir and the sea reaches its maximum extent, leaving

open the floodgates to pass water through the turbines

ADVANTAGES • Auto rolling • Ecological • Silent • Low cost of raw materials

• Do not concentrated population • Available in all weather and time of year.

DISADVANTAGES

• visual and structural impact on the coastal landscape

• Location timely

• Dependent on the extent to surges

• Transfer of power very costly• Negative effect on flora and fauna

• Limited
