Abstract

La présente invention se rapporte à un procédé, à un agencement et à un système 300 pour produire ou générer de l'énergie, en particulier de l'électricité, à partir d'un mouvement mécanique provoqué par un écoulement d'eau, comme par exemple, les courants de marée, d'océan ou de rivière. Le système ou centrale électrique 300 comprend trois principaux types de modules habituellement au nombre de trois ou quatre : une ossature ou armature 70, au moins une turbine ou dispositif de turbine 350 agencé dans l'armature (70), et un ou deux (-2-) éléments de dispositifs de flottaison 40, comprenant un flotteur supérieur 40A et/ou un flotteur inférieur 40B.
