ABSTRACT:
Atmospheric wind is admitted tangentially into a vertically extending structure and directed against the interior curved surface of the structure to produce vortex flow. The structure is open ended and spaced from ground or connected to a ram-air subterranean tunnel. The vortex flow and corresponding low pressure core draws ambient and/or ram air into the bottom of the structure to drive a horizontal turbine.
