. There are two location options which have different costs and outputs.
Firstly
, a wave-energy
machine
has four chambers where
air
moves freely. Once
air
comes from the top of the
machine
, the turbine starts spinning.
This
spin generates more
air
and makes another turbine work. The
air
created by those two turbines goes into another chamber which is surfaced in the
ocean

.
This
air
from the surface of the
ocean
goes up and escapes from the right side of the chamber.
Secondly
,the location options depend on how much cost can be used. If there is a high budget, the
machine
can be set in the deep side of the
ocean
and achieve high output by large
waves
.
On the other hand
, low installation costs lead to a low output by small
waves
.
