Patent ID: 8210792

Claim:
A system for harvesting wind energy, comprising: a wind turbine having an axis of rotation and disposed subjacent to a roof assembly of building; a plurality of conduits disposed adjacent to and extending below the wind turbine, at least a portion of a fluid flow entering the system being channeled through a first conduit, and thence through the wind turbine, and thence through a second conduit substantially opposite the first conduit, wherein the fluid flow from the first conduit to the second conduit is substantially orthogonal to the axis of rotation of the wind turbine; each conduit having a base, first wall, second wall opposite the first wall, proximal end and distal end opposite the proximal end, the base having a length defined between the proximal end and the distal end; a substantial portion of the base defining a curve along the length of the base; and each conduit defining a first portion and a second portion, the first portion defining a larger cross-sectional area than the second portion.
