Power generation using non-buoyant body wave energy converter

Abstract

Worldwide energy consumption is expected to double over the next decades which would eventually lead to depletion and scarcity of energy resources that are being currently used. The increasing demand for electrical energy combined with commitments to significantly reduce carbon emissions within short time frame, is pushing the need for clean, environmental friendly methods of generating electrical energy. The earth s own reserves of fossil fuels such as coal and oil would run out so soon due to their accelerating usage. Scientists and economists strongly believe that the usage of renewable energy sources for generating electricity is highly sustainable and environmental friendly to the present global needs. Despite the advantages, renewable energy conversion technologies face high entry barriers due to its poor economic and availability of fossil fuels at cheaper price. The oceans have attracted many researchers and scientists by showing its huge energy potential in various forms for centuries. Ocean wave energy has the potential to break major barriers through its high availability, density and predictability when compared to other renewable energy sources. More than 70% of Earth s surface is covered by oceans harboring vast untapped energy that can power the entire world. There have been thousands of patents filed all over the world for harnessing this energy to produce electrical energy. Until now, only a hand full of devices reached the level of real sea testing due to the complex nature of ocean waves. Despite the efforts of various governments and researchers, no wave energy technology was found to be commercially viable and this sector is still in the early stages of development. Especially in countries like India, with long coastlines, low average wave density and frequent storms it becomes very difficult for any of the presently available technology to be successful in commercial energy generation. Due to the bitter experience with early attempts
