ABSTRACT
Ocean energy is one of the most promising energy resources. Three- fourths of the earth‟s surface is covered by the oceans. The renewable energy source of ocean mainly is contained in waves, ocean current and offshore solar energy. Very fewer efforts have been made to harness this reliable and predictable resource. A novel concept of on-shore wave energy extraction method is presented. The concept is based upon total energy conservation, where energy of wave is transferred to the flexible converter to increase its kinetic energy. Squeezing action by the external pressure on the converter body results in increase velocities at discharge section. High velocity head then can be used for energy storage or for direct utility of power generation. This converter utilizes the both potential and kinetic energy of the waves and designed for on-shore or near-shore application. Increased wave height at the shore due to shoaling effects increases the potential energy of the waves. This approach will result in economic wave energy converter due to near shore installation. This method is more efficient because it traps both potential and kinetic energy of the waves.

INTRODUCTION

Today most of the world‟s electric power production comes from fossil-fuelled plants. As the demand for electricity is forecasted to increase, there is an urgent need to find new methods to extract electric energy from renewable sources. The annual wave energy potential along the southern Indian coast is between 5 to 15 MW per meter. But the variation of sea-bed topography can lead to the focusing of wave energy in concentrated regions near the shoreline called „hot spots‟. The best spots for wave energy are at Vizhinjam, off Tuticorin and off Andaman islands. As this is a renewable source of energy the future prospects of this energy are high.

WAVE ENERGY CONVERTER (WEC)
Wave energy is the energy from ocean waves, and this energy can be captured to do useful work – for example, electricity generation, water desalination, or the pumping of water. Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
