Abstract

La présente invention concerne un générateur d'énergie marémotrice et, plus spécifiquement, un générateur d'énergie marémotrice ayant un dispositif d'augmentation de la vitesse d'écoulement entraîné au moyen d'un courant de marée, de façon à augmenter la vitesse d'écoulement de l'eau de mer s'écoulant dans un corps rotatif de production d'énergie, qui génère une puissance de rotation pour la production d'énergie tout en tournant au moyen de l'écoulement de l'eau de mer, de telle sorte que le corps rotatif de production d'énergie peut tourner à grande vitesse, et ainsi le rendement de production d'énergie peut être améliorée.
