CONCEPT

BULGE WAVE ENERGY (ANACONDA)

Anaconda uses an entirely novel concept to harvest wave energy.
This resource is free and widely available to the UK and Eire as well as other countries with west facing ocean seaboards.
The inventors (Professors Rod Rainey and Francis Farley FRS) have developed the concept of a distensible rubber tube, floating head to sea, in which bulge waves are excited by passing sea waves. The bulge waves are then used to drive a turbine generator.
It is the long ocean swells which have most energy; developed by winds over hundreds or thousands of miles; these are the ones Anaconda uses.
This is a particularly rich, but as yet untapped, energy resource which Government studies state could produce 3% - 5% of our electricity initially and up to 20% eventually.

RESEARCH BY

The brainchild of Francis Farley and Rod Rainey, the Anaconda is being developed by the Engineering and Physical Sciences Research Council in collaboration with Checkmate Sea energy.
If proven successful, those involved hope to be able to deploy a significant number of these along the British coast.
Each tube is expected to generate around 1MW.
This resource is free and widely available to the UK and Eire as well as other countries with west facing ocean seaboards.

PRINCIPLE
ANACONDA ELECTRICITY GENERATION

1. The device is remarkably simple as there are few moving parts.
2. In principle, the Anaconda could just bob up and down on the currents forever.
3. Electricity is generated via the up-and-down motion of the waves.
4. The waves will hit one end of the tube, thus creating a bulge which is pushed from one end to the other.
5. The bulge becomes bigger and bigger as it runs down the tube until it hits the generator, where the water turns a turbine, and generates electricity.

CONSTRUCTION



it is a very large (perhaps 200m long and 5m diameter) water filled distensible rubber tube floating just beneath the ocean surface at right angles to the waves, with a power take off at the stern.
As a long wave passes the bulge tube is lifted with the surrounding water and this causes a bulge wave to be excited which passes down the tubeâ„¢s walls like a pulse in an artery, gathering energy from the ocean wave as it goes.
Continuous energy gathering is caused by resonance between the bulge wave frequency and the sea waveâ„¢s so energy is drawn in towards the tube from the width of the sea wave crest as it progresses along the tube.

Energy from the sea wave is stored in the rubber as potential energy by it being stretched (in a sea wave it is stored as potential energy due to gravity).
The bulge wave travels just in front of the wave rather like a surfer, picking up energy as it increases progressively in size.
At the end of the tube the bulge wave energy is converted to a surge of water which drives a turbine in the power take off after the flow has been smoothed.
It is a closed circuit system so issues with ingestion of marine animals will not arise. Because it is under the surface and rubber can be formulated to be none polluting, environmental impact will be minimal.

OPERATION

Anaconda uses an entirely new way of harvesting wave energy


.
¢ Wave energy occurs due to movements of water near the surface of the sea. Waves are formed by winds blowing over the water surface, which make the water particles adopt circular motions. This motion carries kinetic energy, the amount of which is determined by the speed and duration of the wind, the length of sea it blows over, the water depth, sea bed conditions and also interactions with the tides.
¢ Waves only occur in the volume of water closest to the water surface, whereas in tides, the entire water body moves from the surface to the sea bed

¢ In Tides, the energy is due to a net movement of water, but in Waves, the water acts as a carrier for energy, moving it in some directions but it does not undergo a net movement itself.

Water from each bulge wave flows under pressure into the upper reservoir of the Power Take Off through a one way valve. Energy storage is due to potential energy against gravity because the reservoirs are at different heights
System pressure being higher then the surrounding sea allows the water to flow under gravity trough the turbine and into the lower chamber. As water leaves the upper chamber, air from the lower chamberâ„¢s air bag goes in the opposite direction to fill the upper chambers so the total volume of the two reservoirs remains the same.

¢ Waves are formed by the wind “ the stronger the wind and the longer the distance over which it blows, the larger the waves and the more energy they carry. For that reason waves on the West Coast of the UK tend to contain more energy than the East Coast.
Essentially, it is very large water filled distensible rubber tube floating just beneath the sea surface at right angles to the waves, with a power take off at the stern.


As a wave passes the bulge tube is lifted with the surrounding. water and causes a bulge wave to be excited which passes down the tubeâ„¢s diameter like a pulse in an artery, gathering energy from the sea wave as it goes. Continuous energy gathering results from resonance between the bulge wave and the sea wave. Energy from the sea wave is stored in the rubber as it stretches.

The bulge wave travels just in front of the wave rather like a surfer, picking up energy as it increases progressively in size.

At the end of the tube the bulge wave energy surge drives a turbine in the power take off after the flow has been smoothed.


Rubber Snake Could Help Wave Power Get a Bite of the Energy Market

A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves.
Its simple design means it would be cheap to manufacture and maintain, enabling it to produce clean electricity at lower cost than other types of wave energy converter.
Cost has been a key barrier to deployment of such converters to date. Named after the snake of the same name because of its long thin shape, the Anaconda is closed at both ends and filled completely with water.
The bulge wave then turns a turbine fitted at the far end of the device and the power produced is fed to shore via a cable. Because it is made of rubber.
The Anaconda is much lighter than other wave energy devices (which are primarily made of metal) and dispenses with the need for hydraulic rams, hinges and articulated joints. This reduces capital and maintenance costs and scope for breakdowns.
Anaconda device would be 200 meters long and 7 meters in diameter, and deployed in water depths of between 40 and 100 meters.




Costs

Initial assessments indicate that the Anaconda would be rated at a power output of 1MW,
(Roughly the electricity consumption of 2000 houses),
Electricity over cost than wave energy converter,
And might be able to generate power at a cost of 6p per kWh or less.

Advantage

Anaconda has the potential to save many millions of tones of carbon dioxide production around the world.
Itâ„¢s also the non polluting
It would be CHEAP to MANUFACTURE and maintain, enabling it to produce clean.




CONCLUSION

Now day our world is affected in GLOBAL Warming. It going on dangerous activities. The power production also makes POLLUTION, so we need a novel RENEWABLE POWER GENERATING source that should not affect our earth. This type of a new source is this RUBBER ANNACONDA.
