PREAMBLE OF INVENTION- This invention in particular describes the nature of the invention and the manner in which it is to be performed.

[i] FIELD OF INVENTION - This invention relates to a system and novel method for generation of electricity, using sea water; specifically the generation of electricity by siphoning sea water at sea shore and converting in to electrical power.

PRIOR ART-

In the existing system as given in United States Patent Application No. 20040228687, wherein, the said invention relates to sea waterpower station. When sea wave is down, sea water stop. When sea wave is up, sea water rise to pool on mountain. Electric generation system is as same as ordinary Waterpower station.

In the existing system as given in United States Patent Application No. 6864592, wherein, the said invention relates to apparatus for converting the motion of sea wave energy to electrical energy that includes one or more float driven linear generators, in which the inertial mass of the float and any linkage means to the linear generator is minimised. In order to generate electrical power consistently upon both the upstroke and downstroke of the float, the moving part of the generator is so sized that its gravitational weight acting upon the float, together with that of the float itself and any intermediate linkage means, is substantially equal to half the total buoyancy of the float.

In the existing system as given in United States Patent Application No. 20090158729, wherein, the said invention relates to waves of the sea moving a float vertically upwards and downwards. These motions are transferred and converted to rotational along a horizontal shaft. The float (1/1) of a spherical or cylindrical shape made with plastic or metal material, empty filled with ballast, floats half emerged and as is moved by the forces of the waves, transfers these vertical motions to a vertical metal beam (1/2) which can be increased or decreased in order to deal with the tidal changes of the sea level. The vertical beam is attached with knuckle joins, at the one end with the float and at the other with the horizontal beam of a rectangular metal triangle which transfers the vertical motions at the horizontally moving forwards and backwards saw (1/5) with the two chains (1/6) and (3/20) which rotate two pairs of gears each gear of a pair to the diametrically opposite side, so that with every movement one gear produces action while the other gear of the pair moves freely. The gears rotate the horizontal shaft which is fitted on them (3/8) and the shaft gives motion to the generator. Thus, every movement of the float, whether upwards or downwards, small or big, rotates the shaft and energizes the generator. This device, from the float to generator forms a unit. Many units, placed in parallel side by side one next to the other, act each one on its own generator or two to three units act together on a common shaft which activates one common more powerful generator. The floats are restricted inside metal cages or inside recesses build in piers so that they will not be carried away by the waves while they are not impede either their vertical motion or the free passage of the seawater. Thus, the device acts as a multi- cylinder petrol engine where the cages in the recesses act as the cylinders and the floats as the pistons with the only difference that this converter uses the endlessly renewable sea water instead of the inflammable, expensive and polluting fossil fuels..

In the existing system as given in United States Patent Application No. 4162409, wherein, the said invention relates to a device for converting the energy of sea waves into electrical energy. A tank-like inlet converter receives sea water from the peaks of waves and discharges it to a water-driven turbine. The turbine drives an electrical generator. Spent water from the turbine is delivered to an outlet converter which delivers the spent sea water to the troughs of the waves. The inlet and outlet converters are provided with controllable water inlet and outlet valves, respectively, which control the flow of sea water into and out of the inlet and outlet converters, respectively.

STATEMENT OF I VENTION-

The inventor has invented a system and novel method for generation of electricity, by siphoning sea water at sea shore; specifically the generation of electricity by converting the kinetic energy of sea water siphoned sea shore through driving a water turbine.

DETAILED DESCRIPTION OF INVENTION-

Accordingly, in one aspect, this invention relates to a system and novel method for generation of electricity, by siphoning sea water at the sea shore.

The present invention converts the kinetic energy of sea water accumulated at sea shore by selecting a suitable place at sea shore. A wave dissipating line is marked during low tide. On that line a wall of minimum 20 meter height is constructed along with hydroelectric power generation system towards the water falling side i.e. on land side. Water siphoning pipe of minimum 60 centimeter diameter with suitable thickness in the system of both the side is fixed. The inlet pipe line is extended towards the sea up to the point where water level should always be above the pipe line. In the out let side, water turbines are fixed along with generators at both-side of the pipe lines at different levels. The inlet of siphoning pipe line is minimum one foot higher than the outlet. This is assured so that the water falls down and does not flow back. The opening and closing valve is the fixed at the terminal of the outlet and inlet pipe line for the convenient and regular operation. Filling point is provided along the valve at the top of the wall portion of the siphon pipe. After the above setup is done, the inlet and outlet valves are closed and the siphoning pipe line is filled with the sea water. Once the filling is done, the filling point is closed air tight and the outlet valve is opened followed by the opening of inlet valve. Then sea water is sucked by power pump from the outlet side and the pump is disconnected as soon as the water is sucked. This leads to sea water continuous fall down on the land side which will again go in to the sea. Falling water force rotates the turbine by which the electricity is generated continuously.

For safer side, inlet pope end is setup closer to the wall and to avoid breaking of inlet pope by strong wave force, a side wall is constructed up to the sea wave's origin point.

In each siphoning system with 20 meters height, one can fix up to 10 turbines which will generate up to 50 mw per year. So by constructing 2000 siphon, one can generate 1 lakh mw per year. Construction cost of one siphon system along with 10 turbines, 10 generators, 20 meter height wall and power house comes up to maximum 1.5 crores Indian Rupees which is way cheaper and economical than any other electrical power plant project.

Thus this invention generates electricity without affecting the environment and is cost effective way of generation of electricity.

This invention is based on the principal of generating electricity through siphoning of sea water. For siphoning purpose, we need higher water level than land level. The higher water level is available in sea only. Sea water level is 1.5 meter higher than land level at any point during low tide and 3 meter height during high tide, which is one source. The second source is the sea wave's; which is one meter to three meter
