Benefits of technology

[0012]In one implementation, the one or more wings oscillate through an arc about the central axis. In one such implementation, the control system reorients the wing according to the speed of the fluid flow and the position of the wing in the arc to maximize efficiency and reliability.
[0013]In another implementation, the one or more wings rotate around the central axis. In such an implementation, the control system reorients the wing according to the speed of the fluid flow and the position of the wing in its rotation to maximize efficiency and reliability.
[0019]The various embodiments provide a mechanism for high output and low cost / time, sustainable energy (e.g., wind or water) via natural currents in a design that is easier to manufacture than most carbon fiber or fiberglass windmill blades at a lower price with a smaller carbon footprint. The design is more environmentally friendly, causing very little harm to the animals or ecosystem, and has a far greater overall energy output than existing technology, as it moves slower than windmills and utilizes cubic area / surface area to be converted into electricity. In addition, it has a much lower minimal amount of natural energy currents necessary for the device to run on, and its improved reliability and resistance to damage from unpredictable weather conditions reduces cost over time. The device mimics a bird's wing as it flaps through the air or a fish's fin as it propels itself through the water, given the nature and properties of the natural energy current, and is scalable to any size. The device can also be organized in wind or water farms to maximize efficiency per square acre of land in use. The device can be built half way underground, or mounted on an above-ground structure (e.g., a tall, narrow circular structure, similar to a telephone poll or typical windmill tower).

Problems solved by technology

However, such energy devices can have a negative impact on the environment.
Additionally, the technology is expensive, and suffers from a number of other problems, including inefficiency and unreliability.
Currently, there exists no device that can generate power from both water and wind currents.
Windmills will only function with wind, and dams and tidal turbines are restricted to an aqueous environment.
This increases development, deployment, and maintenance costs for these suboptimal devices.
These devices also require a lot of space.
Since many regions impose height restriction ordinances, windmills have limited use in populated areas.
Windmills and tidal turbines also suffer efficiency problems in too low of a current and too high of a current.
In low currents, these devices are unable to spin, so no energy can be generated.
In high currents, the devices risk spinning out of control, and require complicated electronic pitching and braking mechanisms.
If these systems fail, there is no mechanical way for the windmill or turbine to stabilize itself, and it may undergo damage.
Additionally, windmills and tidal turbines suffer problems with disturbing the peace.
Windmills and turbines can be noisy and visually intrusive.
Windmills can create a strobing flicker as sunlight passes through the blades, which is known to cause seizures in humans and animals.

Abstract

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.

Description

RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 402,175 filed on Aug. 25, 2010, the entire disclosure of which is hereby incorporated by reference herein in its entirety for all purposes.BACKGROUND[0002]1. Field of the Invention[0003]This invention relates generally to the field of harnessing the energy of moving fluids.[0004]2. Description of the Related Art[0005]There are a number of products that provide a way of generating electricity from moving fluids, such as windmills, dams, and tidal turbines. These devices can be a much better alternative than fossil fuels, natural gas, or other biofuels. However, such energy devices can have a negative impact on the environment. For example, windmills can kill coastal, migratory, or predatory birds and bats. Damns flood valleys, which can eliminate spawning grounds of fish that return to the same place every year, as well as other riverside macro- and micro-ecosystems. Additionally, the ...
