Abstract | The total useful wave resource around the world is estimated to be larger than 2 TW. Harvesting a small portion of the available wave energy resource could contribute significantly to meet the urgent energy demand. Therefore, a lot of wave energy converters have been developed in the past decades. Traditionally, air turbine, hydroelectric motor and linear electromagnetic motor are used in wave energy converters as the power takeoff system. Although these power takeoffs have their own advantages, power takeoffs are still recognized as the most important challenge in ocean wave energy technology. In this paper, a mechanical motion rectifier (MMR) based power takeoff system is proposed and prototyped for wave energy converter. This power takeoff system can convert the bi-directional wave motion into unidirectional rotation of the generator by integrating two one-way clutches into a rack pinion system. A 500W prototype which contains a heaving buoy and MMR-based power takeoff system was designed and fabricated. The models of power takeoff system and the corresponding single-buoy wave energy converter are built and analyzed. Lab testing of power takeoff mechanism and ocean testing of the overall ocean wave converter system are also conducted. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
