Abstract: - This study deals with the idea of wave power to produce electricity in coastal areas of bangladesh. The graphical representation of power vs. Wave height and power vs. Wave period in different locations in bangladesh has been showen by matlab simulation. A self made prototype for wave energy harnessing and its experimental output has also been presented. From many other wave energy conversion technique which one is most suitable for bangladesh is predicted here. Last of all the cost estimation for a small wave plant has been discussed.

INTRODUCTION

The purpose of this paper is to demonstrate that Bangladesh can be enriched in power sector and can reduce the power crisis using wave power. Because wave energy is essentially a non-depleting source of emission free power. Waves are free and will not run out so the cost is in building the power station. It causes less environmental impact on the local communities compared to conventional thermo electrical power generation.There are very few safety risks with wave power generation. The earth is moving time to time. The surface of earth becomes warm more or less due to sunlight and differential heat is absorbed by land and water. These temperature variations cause density variations which influenced by gravity and the moving globe cause winds. This wind creates ripples on still water. As the wind continues to blow the ripples turn into waves and if the fetch is long enough, the waves develop into the great ocean swells . Once formed ocean waves can travel great distances with minimal loss of energy until they break on some distant shore. Thus wave energy is constantly renewed[1]. It varies in intensity, but it is available twenty-four hours a day, 365 days a year.For utilizing this constantly renewed energy, in this paper, we’ve gathered various information like site choice, simulation of wave power with height, design of a wave plant, and experimental output of own created prototype.
