Abstract: An apparatus for improving the generation of wind-powered energy is configured to be placed in front of a windmill. The apparatus has an entry aperture spaced from the windmill blades and having an entry aperture dimension that is greater than the tip-to-tip span of the rotatable windmill blades. The apparatus further includes an exit aperture that is located adjacent the windmill blades and dimensioned substantially equal to the tip-to-tip span of the rotatable blades. Further, a funnel material is spanned between the entry and exit apertures and is adapted to guide wind received within the entry aperture toward the exit aperture and thence to the rotatable blades of the windmill so that a speed of the wind is increased as the wind passes from the entry aperture to the windmill blades.
