A system comprising a blade pitch system having a set of locking holes. A pitch drive assembly is coupled to the blade pitch system and configured to rotate clockwise or counterclockwise within a range of angular degrees to adjust a blade pitch angle. The system includes a pitch lock pin-and-hole system including an interface plate and at least one blade pitch lock assembly coupled to the interface plate. Each lock assembly includes a locking pin having a pin center axis parallel with a center axis of a locking hole to engage a respective one locking hole of the set to lock the blade pitch angle.

A rotor blade for a wind turbine, comprising a rotor blade root for fixing the rotor blade to the hub of a wind turbine, an inner blade portion which extends from the rotor blade root in the direction of a longitudinal extension of the rotor blade, and a rear edge segment for increasing the depth of the rotor blade in the profile depth direction in the region of the inner blade portion, wherein the rear edge segment is fixed to the inner blade portion and has an edge facing the inner blade portion. A cover lip is proposed which overlaps with the edge and is arranged in a transition region from the inner blade portion to the edge of the rear edge segment.

A wind and water power generation system is presented. The wind and power generation system has a roof mounted gutter system with an internally integrated turbine. The internally integrated turbine has a connection to an externally positioned wind scope. Thus, the rain run-off causes the internal turbine to rotate to generate power and the external wind scope allows the internal turbine to turn without rain.

A vortex windmill run by incoming air flow to power a generator by which mechanical energy is converted into electrical energy in order to charge a battery. The vortex windmill includes a plurality of elongated blades having bulbous-shaped edges that are spaced from and connected to a rotatable central shaft, and which are located and rotatable within a cylindrical outer cage, such that when the incoming air flow rotates the blades and central shaft a vortex is formed around the central shaft which aids in maintaining the rotational velocity and momentum of the blades and central shaft during operation and for a period of time after the volume of incoming air flow or the velocity of the incoming air flow decreases, thereby increasing the efficiency of the windmill and the amount of energy produced from the air flow received by the windmill.
