Patent attributes
A wind turbine is provided that has a blade encased into a substantially circular portion of a shell, the shell having an interior surface, an exterior surface, a first end, an opposite second end, and an intake opening between the first and the second end, wherein the first end is closed and wherein the shell has an exhaust opening at or near the second end, wherein wind ingested into the shell through the intake opening is forced to become a vortex having a higher speed than the ingested wind and concentrating the ingested wind substantially near the interior surface of the shell into a spiral air stream traveling toward the exhaust opening, in order to increase an amount of energy harvested by the blade from the ingested wind before the ingested wind, devoid of the amount of energy harvested, exits the shell through the exhaust opening.
