Abstract: An aeolian generator, characterised because it includes a cylindrical vessel (1), a hollow body (2) which is housed in the vessel (1) and which can turn, as a sufficient amount of liquid is contained inside the vessel (1) to keep the hollow body (2) afloat, a cover (23) for the hollow body (2), a series of blades (4) joined to the cover of the hollow body (2), several electric generators (5), wheels (51) mounted on the axles of the electric generators and used to make contact with the body (2) while it turns, supports (61) equipped with rails (6) on which the generators (5) are mounted and can move, and a thrust device used to control the movement of the generators (5) on the rails (6), causing them to move towards the hollow body (2) when it is turning at a certain speed.
