The diagram display the features of a wave-energy
machine
and suitable places to install them.
The wave-energy machine
comprises of two chambers: the upper chamber is connected to the generator and turbine, whereas
, the lower chamber is where the sea water comes in. Air can flow in and out of both chambers.
Electricity is generated by the spinning of the turbines by the wind from two sources: air which flows in from the top valve of the upper chamber and the wind created by the rising of the water levels below, caused by the incoming waves.
Since the power of the generator depends upon how much wind is blowing in, and thus
the strength of the currents, it matters where the machine
is located. The further
the distance from the shore, the greater the output.
The wave-energy machine
is an eco-friendly energy source, relying only the naturally available air and the waves of the ocean.Unauthorized use and/or duplication of this material without express and written permission from this site’s author and/or owner is strictly prohibited.
