WAVE HARNESSING SYSTEM,
 

Tropical seas are low energy seas, so it was essential to store Energy. Thus Experts feel that our system to store Wave energy would perform better and will be a great success.
Another important aspect about our system is the interest we have for  stake holders like Fishermen and Sports lovers. As a Biologist, our Managing director, was  aware of and have taken special care to avoid any possible pollution from the system which would affect Sea life. Besides, the system would be instslled in such a way that it will not interfere with any stakeholders.

Other Ocean power harvesting systems invented sofar produce power in small quantity and thus they require costly converting and integrating  units. Our system is modular and is capable of generating Grid interactive power of 2 to 100 MW or more power.

Thus we feel that our system will, in all likelyhood, would be a successful Invention World over.

 

     Schematic Diagram of the System

The system is simple. The newly invented Three Tire Composite Hydraulic Pump forms the crucial part of the whole system. The ability of the Composite Hydraulic pump has been demonstrated successfully. However, it does require some more development and  fine tuning.  Many such pumps push water using wave energy, to reservoir on top of the hillock adjecent to the coast. From there water runs into hydroelectric generator. Water used is recycled.

Thus the system is based on Hydraulic and Hydroelectric technologies which have a long proven history.

This Composite Hydraulic Pump has three tires. First tire of pump will be under water, and buoys - which heave up and down due to the action of wave movement - operate the pump. Many such small pumps will be connected to another complex tire, which will be installed on the shore. This complex has two parts, the lower part receives pressurized hydraulic fluid from smaller pumps, and ‘builds up pressure’. This in turn pushes a piston in the third tire of the pump and pushes water to a height of over 150 meters."

Ankola DemoBhagirata will have more than 3000 such Composite Hydraulic Pumps to push adequate amount of water to the reservoir on top of the hillock. From there the water is brought down to the Hydroelectric generator to produce 100 MW of Grid interactive power. It is estimated that about 20,000 sq.m of space is required in the sea to produce 100 MW. That means One sq, km area of sea can produce almost 5000 MWs of power.

Even if we assume that just half of this that is 2500 MW would be feasible, that too just for 25% of India’s coastal area (7,500 kms) , an incredible 6 million MW of power can be produced - without any pollution or burning fossil fuel. Fresh water used in the system is not allowed to flow into the sea but conserved and recycled. Thus our system would be the most Ecofriendly system ever designed on this planet.

Though this system, at present, is designed for hilly area near the sea ( from Shiroor to almost beyond Jaitapur and Mumbai of Konkan area, as well as several areas on East coast) with some experience and developments, the system can be adopted to coastal areas without such hillocks.

Cost of establishment of the system in India is estimated at Rs 7.5 to 9 crores(Crore = Ten million ) per MW. This is very close to a Coal based Thermal power plant which costs 6 to 6.5 MW. But it should be noted that as the Wave Harnessing system does not burn any fuel, returns on investment will be very fast & high. --within 5 to 6 years, and profit margin will be very high. No Social costs like pollution, contamination of well water, or contamination of sea water with ash of Fly ash problem and the like. Pure and Clean power till the Sun and    the Moon last.
