FIELD OF THE INVENTION [0001] The present invention is directed to wind power systems and in particular to vertical axis wind systems. BACKGROUND OF THE INVENTION [0002] Vertical axis wind systems (VAWS) are well known. Such systems offer a number of advantages over horizontal axis wind systems (HAWS). One advantage is that the VAWS can harness wind from any direction without having to reorient to such direction such as is required with the HAWS. Another advantage of VAWS is that the blades may be constructed to a much larger scale than HAWS due to the vertical axis orientation. The vertical axis orientation also results in reduced centrifugal stresses on the blade structure. Due to their vertical orientation VAWS also lend themselves to work at higher elevations clear of any obstructions where the wind speeds are higher. [0003] With the growing interest in utilizing wind power systems to replace or supplement power received from the energy grid, or as an alternate source of power to the energy grid, there is a corresponding interest in developing improvements to existing systems. SUMMARY OF THE INVENTION [0004] The present invention is directed to an improved VAWS and components for such systems. [0005] In one aspect the invention provides a vertical axis wind system comprising: [0006] a center post assembly adapted to extend in a vertical orientation, said center post assembly including an outer rotor rotatably connected to an inner post; [0007] a power generation system including a generator rotor rotatably connected to a generator stator, said generator rotor being driveably connected to said outer rotor; and [0008] a blade assembly including a plurality of blades having first and second ends connected to said outer rotor. BRIEF DESCRIPTION OF THE DRAWINGS [0009] The invention is illustrated in the accompanying drawings, which are meant to be exemplary and not limiting, in which like references are intended to refer to like or corresponding parts, and in which: [0010] FIG. 1 is a side view of a vertical axis wind system (VAWS) in accordance with a first embodiment of the present invention; [0011] FIG. 2 is a vertical sectional view of the center post assembly of the VAWS as viewed along lines 2-2 of FIG. 1; [0012] FIG. 3 is a horizontal sectional view of the center post assembly of the VAWS as viewed along lines 3-3 of FIG. 1; [0013] FIG. 4 is an enlarged sectional view of the power generation system for the VAWS as viewed at region 4 of FIG. 2; [0014] FIG. 5 is an enlarged view of the shroud and electric brush system for the VAWS as viewed at region 5 of FIG. 4; [0015] FIG. 6 is an enlarged sectional view of the upper blade attachment assembly for the VAWS as viewed at region 6 of FIG. 2; [0016] FIG. 7 is an enlarged sectional view of the center post assembly for the VAWS as viewed at region 7 of FIG. 2; [0017] FIG. 8 is a perspective view of one end of the blade attachment assembly for the VAWS of FIG. 1; [0018] FIG. 9 is an end view of the blade attachment assembly of FIG. 8; [0019] FIG. 10 is a side view of the blade attachment assembly of FIG. 8; [0020] FIG. 11 is an enlarged side view of an attachment arm for the blade attachment assembly as viewed at region 11 of FIG. 10; [0021] FIG. 12 is an enlarged side view showing the attachment of a blade assembly to the blade attachment assembly of FIG. 8; [0022] FIG. 13 is a top view of the attachment of the blade assembly to the blade attachment assembly of FIG. 12; [0023] FIG. 14 is a partial perspective view of the blade assembly for the VAWS of FIG. 1; Continue reading about Vertical axis wind system...
