Abstract

La présente invention concerne un dispositif de production d'énergie éolienne présentant, par comparaison avec des dispositifs de production d'énergie éolienne classiques, un degré de liberté plus élevé en termes d'emplacement d'installation, moins de bruit et d'impact sur des écosystèmes, et un risque inférieur d'endommagement de pale pendant des temps de vent fort. Un dispositif de production d'énergie éolienne selon la présente invention comprend : une structure externe (40) ; un arbre de transmission de puissance (20) qui est installé de manière rotative à l'intérieur de la structure externe (40) ; un moyen de réception de vent (30) qui est disposé sur l'arbre de transmission de puissance (20), présente une surface de réception de vent, et est structuré comme non symétrique autour d'un point ; et un générateur (10) qui est couplé à l'arbre de transmission de puissance (20).
