Benefits of technology

"The present invention is a new approach to converting wind motion to electrical power using a unique design that incorporates piezoelectric materials. The invention has several advantages over current wind turbine systems, including low-cost, high efficiency, modularity, and low noise and sound propagation. The invention also has a high surface area ratio of cantilevers to inside walls, a specific ratio of air intake window to air outlet window, and an aspect ratio of air jet tunnel that ensures high energy conversion efficiency. The invention is assembled with a basic repeatable and modular small units that can be integrated into any size or shape to provide a wind power generator. The unique design of the invention makes it a more efficient, cost-effective, and adaptable wind energy converter that can compete with fossil fuels in the electric power markets."

Problems solved by technology

These systems are inefficient and expensive to construct and maintain.
They are also noisy, intolerant to damage, and relatively difficult to transport and assemble1,2.
They can also impose safety and environmental concerns.
Unfortunately, a compact, modular, bladeless wind energy system does not exist although some approaches have been proposed.
Air-liquid and liquid-solid interfaces have to be included in such system, resulting in very low conversion efficiency and high cost of manufacture.
It is obvious that most of the wind's kinetic energy is lost in order to move the charged aerosol from one electrode to another.
However, this approach also exhibits low efficiency and high cost because it requires an additional energy-absorbing process to drive the liquid flow in the microchannels where only a weak electric current is induced due to the presence of an electrical double layer in the interface between the liquid and microchannel walls.

Embodiment Construction

[0066]The term cascaded frame, in this detailed description, means that the frame has cross-sections that decrease in size moving from the air intake opening 122 to the air outtake end 124. The term air flow energy is interpreted as wind energy. If a part number in the figures refers to multiple parts, only one or two parts may be assigned the part number, and the same part number may be used for the singular part and the same multiple parts in the figures. The same part number may be used for a generic term such as the piezoelectric material 128 and a specific implementation such as polyvinylidene fluoride (PVDF).

FIGS. 2A and 2B illustrate a proprietary design of a cantilever 102 used in the embodiment. FIG. 3A illustrates the configuration of the air jet tunnel 106 with cascading cantilever array 117 on the side walls 120 showing the path of air flow...

Abstract

In a first embodiment, a wind to energy conversion system is constructed out of a number of modular power units (110), each modular power unit (110) comprised of 36 air jet tunnels (106). Each air jet tunnel (106) is constructed using a cantilever array mounted in a cascaded frame (104) with each cantilever (102) attached on one edge to a window edge of the frame (104). The cantilever (102) is constructed of a brass (130) layer sandwiched between two layers, each layer composed of an electrode (126) attached to a Poly Vinylidene Fluoride (PVDF) (128) layer. Each modular power unit (110) is mounted in a case (108), and a set of cases are mounted in a panel (114) attached to a pedestal (116). The cantilever arrays (117) are wired together into electrical regulating circuits that generate power with a high wind to power conversion efficiency. Other embodiments are presented.

Description

[0001]This application claims the benefit of the U.S. Provisional Patent Application No. 61 / 378,068 filed Aug. 30, 2010 by the present inventors. This provisional patent application is incorporated herein in its entirety by reference.TECHNICAL FIELD[0002]The present invention relates generally to generating electrical power from wind motion energy.BACKGROUND OF THE DISCLOSURE[0003]Current wind power generators generally employ wind turbines and electric motors to generate electricity. These systems are inefficient and expensive to construct and maintain. They are also noisy, intolerant to damage, and relatively difficult to transport and assemble1,2. They can also impose safety and environmental concerns. Unfortunately, a compact, modular, bladeless wind energy system does not exist although some approaches have been proposed. The potential advantages to its development include reduced noise, size, and cost combined with improved portability, efficiency, and cost-effectiveness.[0004...
