Power plant to convert wave energy into electricity

Resumen de: MA66481A1

This invention relates to the field of marine renewable energy. It concerns a power plant with a structure that can be built on a coastline, with several reinforced concrete stabilizers, between which several motion sensors are arranged and arranged in a linear fashion. These sensors follow the waves as they rise and fall, sliding on guide rails integrated into the inner faces of the stabilizers. This arrangement allows the trajectory of the motion sensors to be precisely controlled while protecting them from bad weather and other adverse weather conditions. The linear configuration of the motion sensors also allows the energy of the same wave to be captured several times, ensuring optimal, continuous, synergistic operation and a very high capture rate, regardless of weather conditions or wave height. The dimensions of this power plant can be adapted according to the target production capacity and the hydrodynamic conditions of the deployment area.
