Vertical Axis Wind Wind Turbine - Patent Pending
This has nothing to do with fishing but is another invention I am working on.
VAWT (Vertical Axis Wind Turbine) with High Torque at Low Wind Speeds
The VAWT (Vertical Axis Wind Turbine) explained herein is designed to capture the maximum amount of direct impact wind force within its profile for conversion into torque by presenting blades (flat or curved plates, sails or foils) perpendicular to the wind direction and take advantage of indirect wind forces for additional torque and blade position control. The invention utilizes four large blades pivoting on hinges fixed to radial arms in turn fixed to a vertical shaft and a means of connecting alternate blades to act in pairs.
Using this mechanical pairing method with large blades will provide a higher torque output then other VAWTs of equal profile at lower wind speeds.
Herein described is one method of connecting alternate blade ends in pairs by mechanical means. This will allow the blades to operate in independent pairs so one pair can swing on their hinges while the other pair holds their relative angle to the support arms.
The drawings herein are representative of one means of connecting alternate blades to act in reverse unison meaning as one blade swings inward the alternate blade swings outward thru alternate ≈ 90º segments of shaft rotation while the other pair of blades hold their relative position to the support arms through alternate ≈ 90º segments of shaft rotation.
An alternate method of connecting alternate blades is by use of rack and pinion gears with pinion gears placed at alternate hinges. It is also considered that the blades may be independently controlled by motors or servomechanisms as a method of blade control.
Figure 1 presents a series of plan views sequenced in 30º increments showing the rotation of four blades (1, 2, 3 & 4) connected and supported by hinges (7) mounted on radial arms (6) fixed to a vertical shaft (5). The 10’-0” dimension indicates an example of a fixed distance between alternate blade tips in the 0º position through the 90º position in 30º increments of shaft rotation.
Figure 2 presents a series of plan views showing alternate blades connected by tie bars (8 & 9) with an opening to avoid interference with the shaft are connected to the ends of the blades at hinge points (10). Tie bar (8) connects blades (1 & 3) and tie bar (9) connects blades (2 & 4).
Figure 3 presents series of plan views showing the action of the blades in 30º rotation increments of shaft rotation. During this 0º to 90º shaft rotation segment blades 1 & 3 swing while 2 & 4 do not. During the 90º to 180º segment blades 2 & 4 would swing and 1 & 3 would not. During the 180º to 270º and 270º to 360º the blades continue the pattern of swing and not swinging as happens during the first two 90º segments of shaft rotation.
FIGURE 4 – Figure 4A shows the projected path of tie bar using 15º increments of shaft rotation as input points and Figure 4B shows a tie bar design with a cut path and springs at the ends the path as an example of a means to cushion impact of blades against support arms.

FIGURE 6 – An exploded view of the assembly in figure 5.
Putting them on top of every telephone pole would be the logical place to put them because no new transmission lines or new towers would be required.
