For generating large amounts of power, a number of floats are placed in a row. Many rows are placed side by side along the coast.

Abstract

Dispositif utilisant les marées/vagues océaniques pour produire de l'énergie électrique. Le dispositif se compose de plusieurs unités, chaque unité comportant un flotteur (A) guidé par quatre piliers, deux pompes centrifuges (E, F) pour pomper de l'eau dans le flotteur (A) ou hors de celui-ci, deux contrepoids (U) reliés au flotteur (A) par deux filins. Les contrepoids (U) glissent dans deux rails (S, T) montés chacun de part et d'autre de la structure à quatre piliers. Le mouvement ascendant et descendant du flotteur (A) sur les vagues est transféré vers une crémaillère (B), laquelle déplace un engrenage à pignons (Z) d'une turbine. L'engrenage à pignons (Z) est fixé à un arbre horizontal de turbine. Trois types différents de turbines ont été conçus. Chaque turbine contient des roues libres, des chaînes en boucle (L) et des engrenages permettant d'entraîner l'arbre relié au dispositif dans une direction seulement, à mesure que le flotteur (A) monte et descend. Pour produire de grandes quantités d'énergie, certains flotteurs (A) sont placés de manière à former une rangée.
