Abstract

L'invention concerne un appareil permettant de générer de l'électricité en réponse à un écoulement de fluide. Cet appareil comprend un élément rotor supérieur raccordé à un axe central, qui possède un bras s'étendant sensiblement perpendiculaire jusqu'à l'axe central. Le bras se déplace en réponse à un écoulement de fluide pour faire tourner l'axe central. Cet appareil comprend également un élément rotor inférieur raccordé à l'axe central, qui possède également un bras s'étendant sensiblement perpendiculaire jusqu'à l'axe central. Le bras de l'élément rotor inférieur est sensiblement fixé dans une position par rapport au bras de l'élément rotor supérieur, la position étant décalée sur l'axe central d'environ 90° par rapport à l'élément rotor supérieur. Ledit appareil comprend en outre des éléments rotor intermédiaires empilés entre les éléments rotor supérieur et inférieur, ces éléments rotor intermédiaires étant disposés dans des positions successivement décalées en degrés sur l'axe central, afin d'obtenir le décalage de 90° de l'élément rotor inférieur par rapport à l'élément rotor supérieur, chaque élément rotor intermédiaire comprenant une langue et une rainure afin d'être raccordé à l'élément rotor adjacent. La langue et la rainure de chaque élément rotor intermédiaire sont décalées l'une par rapport à l'autre afin d'obtenir le décalage successif des éléments rotor.
