Abstract

Abstract A technology for maximizing wind to electricity conversion through more fully utilizing bypass air, exterior wind, and static head with the primary objective of generating commercial quantities of electricity. In this application the installation consists of horizontal dual turbine cells connected in tandem to drive a generator. Rows of such cells and generators are designated batteries. Batteries are stacked vertically to form banks. Banks installed end-to-end form arrays that can be extended to any length desired. The arrays present a large frontal area to the wind and acts as a dam to impound the air and create a high pressure on the windward side. The differential pressure adds to the energy of the air flowing through the cells. A cell is comprised of a pair of turbines synchronized to maintain the relative positions of the vanes. The housing is aerodynamically designed for optimal airflow through and around the cell. The airflow around the cell is utilized to exhaust the spent air from the cells to increase efficiency. The vane arrangement more fully extracts the energy from the air flowing through the cell. A secondary application provides for vertically mounting one or more cells that rotate with the direction of the wind.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 169 words
A wind turbine power generating system comprising: a dual turbine assembly cell, where each turbine comprising: a turbine axle, a plurality of generally rectangular shape arms attached to said axle, a plurality of generally rectangular shape vanes attached to said arms, wherein said dual turbine axles positioned in parallel one above the other and spaced their vanes overlap during rotation and provide a frontal resistance to the incoming wind; a housing for said dual turbines comprising: an inlet, an outlet, an inner chamber with inner walls generally fitted to the circumference swept by the vanes; an exterior walls that extend from the apex at the inlet and outlet angling to a segment of the exterior wall parallel to the centerline of the inlet with slots at the said segment of the exterior wall; end walls and intermediate walls as required to support said dual turbine axles; an electrical generator connected to one of said dual turbine axle to receive torque from the turbines during their rotation by the wind.
Claim 2
Dependent Claim 169 words
