Abstract

L'invention concerne un système et un procédé original pour la production d'électricité, par siphonnement d'eau de mer en bord de mer, en construisant un mur de 20 mètres de hauteur minimum au niveau de la ligne où se brisent les vagues au moment de la marée basse et avec un système de production d'énergie hydroélectrique installé du côté où l'eau tombe. On constitue un système de production d'énergie électrique en transformant l'énergie cinétique de l'eau de mer passant à travers le mur construit en bord de mer en énergie électrique, en entraînant une machinerie de turbines hydrauliques. Les turbines sont reliées fonctionnellement à des générateurs d'énergie électrique pour produire de l'énergie électrique et répartir l'énergie au moyen d'un système de transmission d'énergie électrique. On produit l'énergie électrique sans porter atteinte à l'environnement ou à l'écologie et sans utiliser de combustibles fossiles.
