Abstract

La présente invention concerne un générateur gyroscopique simple de réalisation, ayant une structure simple et une résistance élevée, et étant capable de produire de l'énergie de façon stable à un moment quelconque et indépendamment de la position et de la direction du flotteur influencé par onde en garantissant l'isotropie. Un flotteur (2) a une forme annulaire, et un gyroscope à moment de commande (5) présente au moins un axe de cadran vertical (6) à l'intérieur de la partie de tube interne (2A) du flotteur (2). La force de flottaison et la force d'onde sont appliquées à une partie de forme annulaire entre le tube interne et le tube externe (2A, 2B) du flotteur (2), pour garantir la résistance et la rigidité. Un dispositif générateur est disposé de façon compacte dans le tube interne (2A). Comme le dispositif générateur comprend un gyroscope à moment de commande (5) présentant un axe de cadran vertical (6), il n'est pas nécessaire de commander la fixation de la direction du flotteur (2) par rapport à la direction de l'onde avec un précision très élevée. En conséquence, le système peut être significativement simplifié, ce qui permet une production d'énergie stable à tout moment.
