20100276939GENERATING ELECTRICITY USING WIND - Among other things, wind energy can be harnessed without using an outmoded rotational windmill model, which is inherently inefficient because much of the wind energy is bypassed; blade stresses are pronounced; and there is a danger to birds, animals, and in smaller models to people. Efficiency directs rotational devices to be quite large, unaesthetic, and a slur on the environment. Here, the quasi-random movements of hundreds of flexible flaps, called wixels, in an array generates electricity through neodymium magnets and wire coils which move relatively to one another in the wind. Each flap generates small amounts of electricity; the random-like contributions of the many flaps are added electronically using standard methods. The sum is fed negatively into the grid, as in solar panel arrays. Multiple arrays can be arranged as wind farms or can be used on rooftops or back yards without danger. Various colored wixels provide for mobile artistic design, an environmental plus, and in large installations for advertising.11-04-2010

Accordingly, he devised, among other things, an exemplary vertical-axis wind turbine system that includes a novel wind turbine having cup-like blades that exhibit air-foil characteristics. The air-foil characteristics dramatically improve the efficiency of the turbine, not only making it effective at lower wind speeds than conventional wind turbines, but also more tolerant of extreme wind conditions.

In order to reduce the entry of moisture, sand and other foreign substances into the pod and also to reduce the fan noise which reaches the exterior, in accordance with the invention there is provided an arrangement of the fan within the pod, wherein the fan sucks in outside air through a downwardly open first air gap, in particular between the pylon and the pod. In that respect the invention is based on the realization that the air flow along the wind power installation and in particular in the region of the pod has a markedly pronounced horizontal component and at best a markedly less pronounced vertical component. In other words the wind and therewith the foreign substances transported thereby flow at the windward side along the pod to the lee side and have then passed the wind power installation. If therefore air is sucked in through a downwardly open air gap, then at most very fine particles can still also be sucked in, which more specifically can be borne upwardly by the air flow, against the effect of the force of gravity. As a result the suction intake of relatively large particles of sand and dust and also the suction intake of raindrops which, as anyone knows, are considerably heavier, is reduced to a high degree, if not entirely prevented.08-21-2008

20130181458SYSTEM FOR CONVERTING WIND ENERGY - The invention consists of a system for converting wind energy (SCEE) into mechanical and then electrical energy. This system (SCEE) is not subject to the theoretical Betz limit (59%). The system (SCEE) has a wheel (F) provided with a series of blades arranged all around it. The wheel (F) rotates in a pivot connection about a fixed axle (L). Set on the axle (L), a support (E) ensures the fastening of the end-plates of a series of double-acting actuating cylinders (D).

A rigid arm (C) is set on one side of the wheel (F) and held on the other side, in a pivot connection, on a U-shaped section piece (B). Having a circular satellite motion, the latter rotates with the wheel (F) while sliding over a peripheral region of the body (A). When the wind acts on the body (A), the latter pivots with the section piece (B) and pushes the rods of the actuating cylinders (D).

20120086212APPARATUS FOR WIND COLLECTION - The present invention provides an omnidirectional wind collection apparatus. The wind collector includes an outer housing with a peripheral wind inlet circumferentially formed therein. An inner housing disposed within the outer housing has an inner surface with a first opening at a lower end thereof to guide the collected wind to a smaller second opening at the top end. The inner surface is curved between the bottom and top openings to form a progressively narrower passage. The configuration of the inner surface creates a Venturi effect such that the wind is accelerated toward the second opening. A wind pass-through portion is formed above the second opening in the inner housing. Based on the Bernoulli effect, the passage of uncollected wind through this portion creates a low pressure region that expedites flow of collected wind through the first and second openings of the inner housing.04-12-2012
