Abstract
Abstract Electrical energy is produced by platforms floating upon water expanse oceans, seas, rivers or lakes, and movable by waves. The platforms carry electrical generators as well as means transforming the kinetic energy of the waves into mechanical energy which actuates these generators. These means may consist of hydraulic turbines combined with a pump water accumulator capable of transmitting water under pressure to a hydraulic motor operating the electrical generator. Other means may include floats or a pendulum swinging under the action of the waves.
