Abstract: An eolian tower with a rotor of blades connected to devices for converting wind energy into energy of another type, which incorporates a wind-channeling conduit with a narrowing between the intake part and the outlet part which, in one of its possible embodiments, is situated in the central part of the conduit with the rotor arranged in its turn at the center of the narrowing. An eolian tower is also proposed with a rotor which sweeps an area in the shape of a circular crown and channeling conduits with narrowings appropriate to that shape or others that are similar. The eolian tower may also include a wind stimulator at the intake mouth of the conduit and means for closing the same.
