Abstract

La présente invention décrit une façon économique de générer une énergie électrique en extrayant de l'énergie à partir d'une eau s'écoulant dans un tuyau (213) ou un conduit similaire, ladite eau provenant d'une quelconque source artificielle telle qu'un réservoir, une usine de dessalement d'eau et similaire. Une unité de conversion d'énergie comportant une turbine (220) pouvant être montée sur ledit tuyau, activée par ladite eau s'écoulant et reliée de façon fonctionnelle à un générateur électrique (220) et éventuellement à un dispositif de stockage d'énergie, est également fournie, ainsi qu'un moyen pour faire accélérer l'eau qui actionne la turbine en abaissant progressivement la coupe transversale des tuyaux (214, 216) en amont de la turbine. Une pompe (260), actionnée par une partie de l'électricité (228), augmente la pression dans le tuyau (213). L'électricité restante est transmise au réseau électrique (150) des consommateurs.
