The power generation in two

different geographical placeswhich are floating. They are

1.On OCEAN

2.On LAND

In this plant both wave and wind

energy has been used to develop greater

efficiency for generation of electricity.

Poseidon 37

ON OCEAN


4/14

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.

Construction

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.

i Three 11 kW Gaia Wind

turbines

iAnnual production:30,000kWh pr. turbine

i Hub height: 12 meters

i Rotor diameter: 13 meters

i Optimal yield in moderate

wind speeds (annual

average wind speed 4.5-

7.5 m/s)

i Installation of turbines


11/14

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:


12/14

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

Energy output


14/14

i Ability to harness the energy intensive waveand wind resources found at deep sea.

i Invisible from shore (sight and noise)i High power output/footprint ratio

i Highest wave to energy conversion efficiency inthe industry

i Low service costs.i Accessible during harsh weather. (kW/m)

Annual average wave energyiUses existing marine engineering and

manufacturing capabilities and eco-friendly.
