In this plant both wave and wind
energy has been used to develop greater
efficiency for generation of electricity.

Only solution in the world that convertsboth wave and wind energy.
Exploits wind and wave resources in Deep
Ocean waters due to the proprietary floatingfoundation. It is 100% green, making it worlds largest
generating power station inexistence tillnow.
Efficiency to generate up to 50 giga watts ofhydro and wind power a year.
Energy cost to be 11 cents/kilowatt hour bya Danish company.

1.An ultra stable floating foundation for a hybrid
renewable solution designed for deep ocean
operation invisible from shore.
2.Wave energy harvesting using patented floats
to extract energy from the waves and transform
this to power.
3.Wind turbine on floating foundation significantlyincreases the potential sites for off shore wind.

we can find two new methods for
generate energy from waves.
1)Floating wave energy extractor
2)Near onshore based wave
energy extractor

The system is a huge mass body supported by a large no ofpiston shafts.
The upper section of each of the shafts have pistons and thatpistons can move up and down through the cylinders
With the up down motion of the waves ,the lower parts of theevery shaft are having a floating air column.
The upper side of the cylinders has two valves.1.one to a high-pressure fluid pipe and it will open when the
column is on the crest2.The next valve is connected to the
low-pressure fluid pipe and theywill open when the column is onthe trough.

WORKING of the system
The floating air columns that on the crest, move
upward direction with the upward movement of the
waves .
This upward movement of columns pushes the piston
in same direction.
When the waves are passing through thefloating air columns,

Then these pistons would increase the pressurize of fluid
inside its corresponding cylinders and the fluid in it will rush to
the high pressure fluid pipe with high pressure. Since the high pressure fluid pipes are inter-connected, the
net pressure will focus on the turbine. The turbine rotate in
high speed.
As the turbine rotate, the generator coupled to the turbine
generates electricity. As some of the air columns that on the trough move down
ward direction because of the gravity, the pistons of those air
columns also move down ward.
As this pistons move down ward, there will be a vacuum
created in its cylinders and the hydraulic fluid in the lowpressure fluid pipe will enter to these cylinders and filled .
The low pressure fluid pipes are also inter connected, the
low pressure fluid will be entered to their cylinders and filled
and ready for the next fluid compression when the next crest
of waves approach to them.

a) The system can install anywhere there issufficient waves are
present because of it is in depended to the
nature of the site.
b) It probably will not cause any impact on the
nature.
c) The system can construct in an onshore
factory and easilytransport to the ideal sites with a simple pulling
boat.
d) Whole of the metallic- corrosive parts of the
system like turbine,
SOME ATTRACTIVENESS OF THE TECHNOLOGY:

a) Violent cyclonic wind and there by the giant
waves may cause
stability problems.
b) Perfect anchoring of the systemc) Depth of the sea.
Difficulties:
Transmission:
The power can be transmitted tothe grid through
the immersed insulated
electric cables
