Abstract

Une pluralité de dispositifs gonflables (50a-f) sont reliés entre eux pour former une boucle (48) qui est limitée dans ses déplacements de manière à ce qu'un segment de la boucle soit placé à un niveau de référence inférieur à une profondeur donnée dans un premier volume d'eau (24), à ce qu'un autre segment de la boucle soit placé à un niveau de référence supérieur situé au-dessus du niveau de référence inférieur, à ce qu'un autre segment de la boucle s'étende sur une première trajectoire qui s'étend généralement en hauteur entre le niveau de référence inférieur et le niveau de référence supérieur et à ce qu'un autre segment de la boucle s'étende sur une seconde trajectoire généralement parallèle à la première trajectoire et vers le haut entre le niveau inférieur de référence et le niveau supérieur de référence. Au moins une majorité des dispositifs gonflables (50d-f) occupant la première trajectoire sont gonflés avec du gaz et au moins une majorité des dispositifs gonflables (50a-c) occupant la seconde trajectoire sont dégonflés si bien que les dispositifs gonflables (50d-f) de la première trajectoire se déplacent vers le haut et que les dispositifs gonflables (50a-c) de la seconde trajectoire se déplacent vers le bas. Lorsque chaque dispositif gonflable (50a-f) approche du niveau de référence supérieur, il est dégonflé par un équipement de compression (52) qui emploie une température différentielle pour actionner de manière régulée le tube en nitinol. Le déplacement ou mouvement des dispositifs gonflables est utilisé pour élever de l'eau (25) qui coule, par la force de la gravité, dans une installation (28) hydroélectrique produisant de l'électricité.
