    摘要: A wind turbine device of increased efficiency is comprised of a set of fixed airfoils that direct wind into a rotor having a plurality of blades. The fixed airfoils may extend to the ground to increase the amount of wind directed into the rotor and may be manufactured from concrete. The rotor blades have a vented portion near the axis of rotation that has been found to increase efficiency for certain blade geometries. For other blade geometries, increased efficiency is observed with no gap at the axis of rotation. The rotor may also be manufactured from composite materials to increase strength while decreasing the moment of inertia for the rotor.

    摘要: Disclosed are various embodiments of cross-wind turbines that are capable of providing high efficiencies over a wide range of wind velocities. An airfoil stator causes wind to accelerate along its surface and creates a low pressure area on the leading face of the rotor blade during the power stroke. A blocking stator blocks wind from impeding the movement of the rotor blades during the return cycle and directs wind onto the trailing face of the rotor blades during the power cycle. A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system.

    摘要: A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system. In addition, an integrated power plant is disclosed that provides a source of renewable energy in the form of a cross-flow wind turbine that includes solar cells mounted on south facing surfaces of the stators. The stators can be used to store liquids and fuels generated by the renewable energy sources. Electrical power generated by the renewable energy sources can be used in a desalination process to generate pure drinking water that can be stored in the stator devices. Electrical energy generated by the renewable energy sources can be used in an electrolysis device to generate oxygen and hydrogen gases. The oxygen and hydrogen gases can be used to operate a fuel cell to generate electricity when needed. The hydrogen can also be used to operate a hydrogen engine that runs an auxiliary generator to supply auxiliary electrical power when needed. A biofuel engine, propane gas engine, natural gas engine, or diesel engine can also be used to run the auxiliary generator. Mechanical power from the wind turbine can be used to run mechanical pumps to pump water to a reservoir at a higher elevation, which can then be used to run a water turbine that is connected to the auxiliary generator to generate electrical power when needed.
