electricity production.

Overall

, there are a number of stages in

this

complex process ,beginning with the waves that reach the surface and

then

provide

air

for a machine .

This

technology uses the power gained from natural processes and sources like water . First , the flux of the seawater comes to the cliff ,under the chamber. At

this

moment, the

produced by the wave puts the turbine in function ,which rolls continuously in the same direction.

Consequently

, it generates electricity

due to

the power of rotation .

Finally

, the proportion of

air

comes out through the tunnel between the columns .

On the contrary

, when the sea level decreases, the

air

direction changes and it returns to the point where it was formed.

This

is the second time when the electric current is increasing

due to

the pressure which is created by masses of

air

moving back to the sea wall .

As a result

, both of these stages are similar with the same goal and the particular alteration appears to be only about the

air

direction.
