Horizontal Wind Turbine

Abstract

The present invention is directed to a system and method for collecting energy from a prevailing wind. The system and method include a concentrating structure having a surface substantially facing an unobstructed expanse of a terrain and/or water communicating the prevailing wind toward the surface. The surface is configured to deflect and concentrate the prevailing wind. Also, the system includes a wind turbine having a rotational axis substantially horizontal and perpendicular to the direction of the prevailing wind. The wind turbine is mounted adjacent to the structure and situated to receive the concentrated wind.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a conceptual drawing of an elevation view illustrating the concentrating effect that a sloped obstruction has on the prevailing wind generating higher than ambient wind velocities.

FIG. 2 is a conceptual drawing of a plan view illustrating the concentrating effect of vertical obstructions used to channel airflow into a wind turbine.
