The extension of the extendable arm may be done automatically in response to achieving a threshold value of preset criteria, or may be adjusted manually. The extension of the extendable arm may be done automatically in response to arriving at threshold of a preset criteria, or may be adjusted manually. The counterweight 910 suspended from or acting on the extendable arm 922 provides a force to at least partially restore the displaced wind lever back towards the substantially vertical orientation where the wind capture ½ cycle began. The counterweight 812 is coupled to the pivot point via an extendable arm 824. The arm 824 supporting the counterweight 812 may be an extendable arm to change the distance of the weight from the pivot point to vary the amount of torque required to move the extended element 808. By controlling the required torque, the size of the oscillations that the extended element 808 is made or allowed to perform may also be controlled.

Operationally, the current may be collected at the contacts 506 and 508 via a connection with out bound contacts 516 positioned on the pivot section 502 a and passed to an electrical grid, or a storage device, such as a battery or capacitor. In one embodiment, it is understood that changing the sail or blade surface area and keeping other system variables, such as wind speed, wind acceleration, wind turbulence, counter weight and magnetic fields constant, corresponds to an increase or decrease in the wind energy that may be harvested using the wind power system 800. For example, using the sail pivot 809, the sail 102 may be deployed to provide a large wind facing surface area for initial wind capture during the wind capture ½ cycle. In some instances, a physical condition may be created, such as a pressure or temperature gradient, to control the air movement and create the motion that provides the mechanical energy.
3, wind pressure and air currents impinge on the blade causing the blade to move about a pivot point 302. As the wind currents naturally ebb and flow, the blade 102 may oscillate back and forth about the pivot point 302. The back and forth movement of the blade 102 may be quantified as a variable degree of rotation relative to a centerline 318 of the wind power system 300. The blade 102 may oscillate less than 360 degrees from the centerline 318. In some embodiments, the blade 102 may oscillate from between approximately 0 and ±90 degrees from the centerline 318, for example, approximately between 0 and ±10 degrees, preferably approximately between 0 and ±5 degrees. Dolor de la pierna . Generally, the physical configuration of the wind-energy conversion system produces an asymmetric force in the naturally occurring air currents or “wind” to control the air movement. 3-7. For example, the function of the counterweight 812 shown in the embodiments of the wind lever assembly 802 may be provided by replacing the counterweight 812 with one or more magnetic elements, or a wire coil, disposed at the end of the extended arm 824. The magnetic elements, or the wire coil, are used in conjunction with a corresponding wire coil or magnetic element, respectively, which are positioned, for example, in the open space 822. The relative movement between the magnetic elements and wire coil may be used to generate an electric current as described above.
From a generally vertical orientation relative to the ground, the sail is displaced either clockwise or counterclockwise about the pivot point during a “wind capture ½ cycle.” The movement of the sail, in turn, moves or rotates the shaft 826. The shaft may be directly connected to the generator 804, or may be connected to an intervening drive assembly 828. As described above, the drive assembly 828 provides a capability for adjusting the rotational speed of the shaft for providing an altered rotational speed to the generator 804, if desired. Typical horizontal axis wind turbines having multiple rotating blades are made to endure enormous destructive wind forces during operation. The sail returns during the lever return ½ cycle to its initial position. The base 818 may be made to any suitable height dimension that places the extended element 808 in an optimal position for receiving a suitable wind current and that minimizes ground effects on the wind current.

The advantages of the present disclosure may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the disclosure and any appended claims. The movement of the wire coil 512 resembles the swinging of a pendulum. In one embodiment, physical stops 1104 may be positioned on the frame 912 to limit the movement of each slidable member 1108 along the frame 912 to control the amount that the wind deflector 1102 rises, and thus control the change in the effectively exposed surface area of the wind deflector. SUMMARY In one aspect, a wind energy collection system is provided that includes a wind lever assembly coupled to a base; and a rotatable support member supported by the base and coupled to the wind lever assembly. In another aspect, a wind energy collection system is provided including a wind lever assembly having a wind lever and a counterweight.
