This paper presents an innovative vertical perforated breakwater for protecting the shoreline from sea water wave energy and converting the transmitted water wave energy to renewable energy through vents inside the body. This structure is composed of a vertically faced rectangular shape with a number of vents that differ from some ratios of porosities tested first as a wave energy dissipater by warning the wave height sensors before and after the seawall and analyzing the total energy transmitted to push it to an innovative system producing renewable electric energy by adapting the location of these vents and changing the dimensions of these holes in three models with dimensions (8 × 4, 4 × 4, and 7 × 6, respectively, dimensions in cms). By choosing five heights of water depths (15, 19, 23, 27 and 31 cms) and four eccentricities of the wave maker, we also recorded the volt and ampere and finally the total percentage of wave energy that could be converted. These experiments were carried out in a recirculating open channel flume located at the Hydraulics Engineering Laboratory at the Higher Institute of Engineering in El Shorouk City.
