Abstract

La présente invention concerne des centrales éoliennes dans lesquelles un corps volant glisse vers le haut ou vers le bas de façon périodique sur un mât grâce à la poussée vers le haut ou vers le bas engendrée par le vent, avec l'aide de gouvernails de direction qui agissent sur l'orientation spontanée du corps volant dans la direction du vent, la direction de déplacement du corps volant étant modifiée par inclinaison ou rotation au niveau des points d'inversion équipés de moyens techniques correspondants, aux extrémités du mât. Le corps volant génère donc dans les deux phases de déplacement de l'énergie cinétique qui peut être transformée directement en énergie électrique au moyen d'un générateur linéaire ou qui peut être transformée en énergie mécanique par le biais de câbles, de chaînes ou d'éléments similaires et éventuellement en énergie électrique au moyen d'un générateur. En tant que mât, il est possible d'utiliser des cheminées, des mâts de bateau, d'autres mâts et des arbres existants.
