Abstract

L'invention concerne un système de génération d'énergie électrique par utilisation d'électrique provenant du mouvement des vagues (énergie houlomotrice), basé sur le déplacement vertical d'un contrepoids. Le système se trouve à l'intérieur d'une carcasse, qui agit comme une bouée, et qui est motivée par l'action de la houle. Le contrepoids est relié par un câble d'acier, enroulé dans un trévire, à un poids mort mouillé. Le mouvement ascendant du contre-poids s'obtient lorsque la bouée se soulève sous l'effet de la houle. L'énergie potentielle acquise par le contrepoids lorsqu'il monte est exploitée durant son mouvement descendant pour générer de préférence de l'énergie électrique.
