BACKGROUND OF THE INVENTION
Ocean is a source of never ending surprises and unsolved mysteries. Tidal waves are constant source of untapped energy since ages and an unsolved riddle for human mind. It is a well-known fact that hit the shore with excess of energies which if tapped can do miracles. Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity.
Although not yet widely used, tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power. Among sources of renewable energy, tidal power has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability.

By suitably selecting the diameter of the piston, required pressure on water in the cylinder can be exerted to desalinate water through Reverse Osmosis. However, many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels.
Thus, the present invention provides an improved and inexpensive system and method to draw abundant energy from tidal waves by trapping compressed air produced.
