Abstract

éolienne comprenant un ou plusieurs ensemble(s) d’aimants opposés pour créer une force de répulsion entre un support de turbine et un rotor de turbine qui est suffisamment puissante pour former un espace entre ceux-ci, réduisant ainsi le frottement entre le support de turbine et un rotor de turbine. La réduction du frottement entre le rotor de turbine et le support de turbine permet une augmentation de la production d’énergie et de la taille des éoliennes.
