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

Summarize the information by selecting and reporting the main features and make comparisons where relevant.

You should write at least 150 words.
These provided diagrams illustrate the structure of a
machine
which is manufactured mainly to create
electricity
as a result
of the wave effect.
Overall
, it can be seen that the
machine
was composed of two chambers, and there were two types of them which relied on the kind of wave.
To begin
, a specific
machine
was designed to produce
electricity
, but the location of water determined the type of waves small or large. So, when waves were large, the costs of installation for the
machine
increased, and the output of
electricity
was high.
In contrast
, when waves were small, the cost to install the
machine
declined, and the produced amount of energy was low. Regarding how the
machine
operated,
firstly
, it was fixed in the water where the wave entered the lower chamber,
therefore
; it pushed the air to flow rapidly in the second chamber, so; it enforced the lower turbine to rotate,
then
; the air moved to the outside. After, that the air could enter from the outside to enforce the upper turbine to move.
Finally
,
electricity
was generated
due to
the movement of turbines.
