Seapower GEL

The system for the exploitation of energy from waves has been developed by Seapower SCRL in collaboration with Umbra Group, a world leader in the production of linear actuators with recirculating ball bearings. The wave system is constituted by a pivoted floating body, connected to a support structure, free to oscillate around a horizontal axis under the action of the waves. The permanent magnet electric generator, integrated in the Power Take Off (PTO)actuator/generator, allows the transformation of linear motion induced by waves into rotary motion of the generator rotor. A floating body of about 5 m beam can produce power of around 60 kW out of a wave of heights of 1.5 meters. In an Italian site with enough energy (eg west coast of Sardinia), the system can produce approximately 150,000 kWh per year. A 1:5 scale model of the system has already been tested in the towing tank of Department of Industrial Engineering (DII) of University of Naples “Federico II”, and the next steps will be the floating body geometry optimization followed by the manufacture and testing of a full-scale prototype of 60 kW.
