Abstract

La présente invention concerne un dispositif de génération d'énergie marémotrice, et plus précisément, un dispositif de génération d'énergie marémotrice dans lequel un arbre d'entraînement est mis en rotation à l'aide d'une pluralité d'hélices qui sont plongées en dessous du niveau de l'eau de telle sorte qu'un générateur situé au-dessus du niveau de l'eau est capable de produire de l'électricité. Selon la présente invention, l'invention peut facilement être transportée et installée par des grues ou similaires dans des zones de la mer où le courant de marée est fort, produisant ainsi de l'électricité de manière peu coûteuse et permettant de changer facilement l'emplacement d'un site de génération d'énergie en fonction des changements environnementaux.
