The diagrams below show the design for a wave-energy machine and its location.

The diagrams show the structure of the hydro-power plant and the location at which it could be placed.

Overall

,

it is clear that

the more expensive hydro-power station generates larger amounts of electricity, compared to the cheaper one. The structure of the wave-energy

machine

is comprised of two chambers, one for holding water and the other for

air

. There are two holes at which the

air

enters and leaves.

Furthermore

, when the water fills the water chamber, it pushes the

air

into the turbines, where it spins to create electricity.

After

this

, the

air

leaves the

machine

through the

air

outlet. When considering the location suitable for the installation of the hydro-powered machines, the

machine

in deep waters produces a high output;

however

, the cost involved in constructing

this

is high.

On the other hand

, the shallow-based

machine

that deals with small waves produces lesser output compared to the deep ones, but the amount of money required to build

this

is low.
