A method is provided for generating power through artificially induced wind flow. Naturally available energy such as sunlight is used to create high and low air pressure areas artificially in two separate chambers or regions. The two areas are connected together through a tube, which results in wind flow from the higher air pressure area to the lower air pressure area, which wind flow is used to power wind turbines which in turn generate electric power. The method provides an alternative to existing methods for power generation from wind energy or solar energy, such as natural wind farms, photovoltaic cells and solar-thermal systems.

The Geothermal Wind System is a hybrid power production system using geothermal transfer of heat between native rock and an air mass circulating between two or more portals of substantially different vertical elevations by use of the stack effect and the buoyancy of heated air or gravity pulling cooled air to turn one or more wind turbines which drive one or more generators. This wind speed can be improved by use of a venturi valve in close proximity to the turbine(s). A novel example of an aerodynamic, adjustable radial venturi is also herein incorporated. Two modes of the GWS are herein described, one used at shallow depths having geothermal temperatures approximating the average exterior climate, and the second used with geothermal temperatures found at greater depths at substantially higher than outside temperatures. The GWS is a non-polluting, non-carbon burning, non-water-dependent power production system easily implemented in third world countries.

An apparatus and method for producing high output and low cost/time, sustainable energy (e.g., wind or water) via natural currents that is environmentally friendly and includes a gravity-assisted equalizing control system is provided. Wings with a large surface area can be included in the design, as well as an optional counterbalance system that synchronizes the wings' position and speed with a mechanical leverage point on the body of the device. When a fluid flows past wings of the device, the fluid flow induces motion in the wings, which causes a shaft to move, creating torque at the generator. The outcome is a coordination of harmonizing the wings pitch angle to the natural frequency of a fluids specific velocity. The device can adapt itself to the velocity of the surrounding fluid through a rotational sweeping control system that produces a more streamlined profile to maximize reliability.

An inventive wind turbine device including an air intake with a curved interior surface for accelerating wind speed and an optional conical component to direct the captured wind directly to a portion of the turbine housed in the throat of the device. Annular slits are optionally included in the air intake to reduce back pressures of the introduced fluid stream. The device has an exhaust portion with a curved interior surface for discharging the wind. A method of generating electricity regardless of external wind speed by channeling wind into an air intake of the device, passing the wind over the curved interior surface of the intake thereby accelerating the wind speed through the device, reducing the back pressure in the intake by discharging a portion of wind through annular slits therein, and using the accelerated wind to generate electricity is also encompassed herein.

This invention describes a device effective in maximizing the power output of a rotor in a fluid. This turbine uses a rotor (2) similar to HAWT but placed in a vertical position enclosed in a static diffuser with the shape of an inverted wing. The motionless structure (1) is influenced by two combined flows, enhancing the energy produced by the rotor (2).The rotor (2) is connected to an element of transformation of mechanical energy integrated in the structure (1) with an aerodynamic shape of an inverted wing. The system does not have an orientation mechanism with the direction of the wind since it is completely omnidirectional and presents only one movable component, the rotor (2) with blades (3). The turbine may still comprise an aerodynamic deflector in a brim (6) in the upper part of the structure (1) and is divided in multi-elements (9) with at least two aerodynamic elements.This invention is applicable in the energy producing energy with the micro-generation, as well as large power systems.
摘要:
A wind turbine is disclosed which uses energy in air moving relatively toward the turbine to focus and increase the velocity of air entering a turbine inlet air flow passage. The inlet flow passage discharges focused and accelerated air to blades of a rotor where the blades interact with that air to turn the rotor. Rotor motion can be used to operate an electrical generator. The plane of rotation of the rotor can be at substantially right angles to the plane of the passage inlet opening. Baffles in the flow passage and stator vanes adjacent the rotor blades cause the mass flow of the accelerated air to be substantially uniform, and desirably directed, throughout the rotor's blade area. The turbine is compact and operates quietly.

A tubular housing can include at least one fixed helical vane formed onto the inner surfaces of the tubular housing in a spiral and adapted to direct fluid into a spiraled flow and focus fluid onto a fan blade assembly associated with an alternator system and located within the tubular housing before a system exhaust. A generator cone can be mounted near the center and front of the fan blade assembly facing fluid passing through the tubular housing. As fluid passes over the generator cone it experiences compression between the generator cone and housing resulting in increased pressure and velocity of the fluid, thereby increasing rotational speed of the generator blades and generator as the compressed, spiraled fluid passes through the blades and exits the tubular housing. The system can be used for fixed or mobile applications in water, wind and manually induced fluid flow.

A storage energy generation method utilizing natural energy and a generation system thereof generates electricity through natural energy such as wind power or solar energy and then compresses air, or directly compresses air, then generates electricity to an electric grid through the compressed air which is deemed as a power resource. An electric station utilizing integrated energy generates electricity to drive an air compression device, further then produces compressed air as an energy storage medium and stores compressed air in an air storage device, and then regards the compressed air as a main or auxiliary driving energy to other electric stations, such that a function of stabilizing and adjusting peak load can be realized.
