  • the present invention meets these needs by providing a wind energy system in which a queue of wind turbines is concealed in a conduit that can be at least partially buried in the earth. Such a system also permits utilization of electricity generated in remote areas; off- grid systems can be used to generate hydrogen.
  • the present invention comprises a wind energy system for providing electricity to an electrical facility for storage, consumption or further processing.
  • the system comprises an air conduit having an inlet and an outlet.
  • a plurality of wind turbines are queued up along the length of the air conduit.
  • An electrical generator is coupled to each of the plurality of turbines to convert rotational energy from the turbines into electricity.
  • the generator is electrically connectable to the electrical facility.
  • a wind collector assembly extends outwardly at least partially around the inlet of the air conduit.
  • FIG 1 is a schematic of a preferred embodiment of the wind energy system of the present invention.
  • a partially buried culvert houses a plurality of wind turbines arranged front to back in the culvert.
  • the inlet end of the culvert opens near the top of a mound of earth, such as a hill or ridge, and is flanked by sails for collecting wind and funneling it into the culvert, where it will run the turbines.
  • Figure 2 is plan view of the system of Figure 1.
  • Figure 3 is an end view of the inlet end of the system of Figure 1.
  • the wind energy system 10 of this invention is designed to provide electricity to an electrical facility 12, such as a power plant.
  • the electrical facility 12 may serve to store, transfer or transform the electrical power. Depending on the nature of the electrical facility 12, it may be connected to the power grid at 14a or connected to another off-grid facility at 14b, such as an electrolysis plant for producing hydrogen. Alternately, the electrical facility 12 may be any system that consumes power, such as a dwelling or other building or structure that utilizes electricity.
  • the system 10 comprises an air conduit 16 having an inlet 18 and an outlet 20.
  • the conduit 16 may by any suitable size, shape or configuration selected to cooperate with the other components of the system 10 described hereafter.
  • the conduit 16 is adapted to receive wind in the inlet 18, to conduct the wind through the conduit, and to release the release wind through the outlet 20.
  • the conduit 16 is a solid tube conveniently formed of pre-cast concrete of the type used to make drainage culverts and the like.
  • PVC polyvinylchloride
  • the length of the conduit 16 is about 100 feet and the diameter is about 24 feet.
  • the conduit 16 is at least partially buried in the earth. This provides the system 10 with a low and inconspicuous profile on the landscape or may even totally conceal it.
  • the conduit 16 is partially buried in the earth 24, as best seen in Figures 1 and 3.
  • the conduit 16 preferably is positioned so that the inlet 18 opens at the top of an earthen slope 26 so that the slope extends outwardly and downwardly from the inlet.
  • the slope 26 may be formed by a man- made berm or embankment or a natural hillside.
  • the slope 26 has a grade of about 30 to about 45 degrees relative to the longitudinal axis of the air conduit 16.
  • the system 10 further comprises a plurality of wind turbines designated collectively at 30.
  • wind turbine means any device or machine capable of converting wind into mechanical power. Examples of wind turbines include those devices characterized by a plurality of foils, such as vanes, blades, or sails, fixed to a rotor so that pressure from wind impacting the foils will cause the rotor to rotate.
  • the blades designated generally at 32 have a front wind gathering or face side and an opposing rear or back side.
  • the wind turbines 30 are queued up along the length of the conduit 16.
  • queued up denotes an arrangement where the turbines are positioned front-to-back in a line, with the front or face side of the turbines facing the inlet 18 of the conduit 16.
  • the conduit 16 forms a casement for the wind turbines 30 and that the shape, length and diameter of the conduit 16 may be selected to maximize the air dynamics of the system 10.

  • generator 36 for each turbine 30, as shown herein. Alternately, one generator may serve two or more of the turbines.
  • the electrical generators 36 thus convert rotational energy from the turbines 30 into electricity.
  • the generators 36 are electrically connectable to the electrical facility 12 through wires 38 in a known manner.
  • the turbines are small wind turbines. Suitable turbines are available from Bergey WindPower Co. (Norman, Oklahoma), such as the Bergey Excell, which is a 10 Kw unit with a rotor span of 7 meters (about 23 feet). Preferably, the turbines have a blade span that permits the diameter of the conduit or casement to be minimized, and are designed to optimize effectiveness in concentrated wind environments. In addition, these turbines come equipped with built-in generators/alternators, simplifying assembly and installation in the system 10.
  • the system 10 preferably includes a wind collector 40 extending outwardly at least partially around the inlet.
  • the collector 40 may take various forms. It may be a unitary structure or composed of several parts. It may be rigid or pliable. In the preferred embodiment illustrated herein, the collector 40 is formed in part by the earthen slope 26 extending downwardly from the inlet 18, as previously described. In this embodiment, the wind collector 40 also may include one or more sails designated generally at 42. The sails 42 may be formed of various materials. A preferred material is sailcloth or some other durable, pliable fabric.
  • the sails 40 advantageously include a pair of lateral collectors such as the lateral sails 46 and 48 and an upper, central collector, such as the spinnaker or topsail 50, shown only schematically in the drawings.
  • the lateral sails 46 and 48 flank the inlet 18 of the conduit 16 extending upwardly from the earth 24.
  • the spinnaker 50 is mounted between the lateral sails 46 and 48 above the inlet 18, generally extending from the top of the lateral sail 46 to the top of the other lateral sail 48.
  • the lateral sails 46 and 48 and the spinnaker 50 may be retractable for wind management and control.
  • the retraction mechanisms may be manually operated or hydraulically driven.
  • the lateral sails 46 and 48 are independently deployable for maximum capture of transverse winds.
  • the lateral sails 46 and 48 may be mounted on hydraulically controlled masts 54 and 56 and arms 58 and 60, which are supported in fixed piers 62 and 64 planted firmly in the earth 24, and extendable from a collapsed position near the ground to a partly or fully deployed position as illustrated in the drawings.
  • the spinnaker may be mounted for downward deployment, partly or fully, as indicated by the wind direction and speed.
  • the devices for mounting and deploying sails and spinnakers are well known and, therefore, no detailed description is provided herein.
  • the wind energy of the present invention provides several advantages.
  • the turbines are concealed in the conduit, which itself may be hidden or at least partially buried in the earth. In this way, the visual effect on landscape is minimized.
  • the wind collector at the inlet end of the conduit increases the wind volume that enters the conduit and increases the effectiveness of the turbines, queued up inside the conduit.
  • a small, visually obscure wind energy system as described herein makes the use of wind energy more widely available and thus reduces the reliance on more expensive and exhaustible fossil fuels.

Abstract

L'invention porte sur un système d'énergie éolienne comprenant une file de turbines reçues dans un conduit d'air horizontal. L'extrémité d'entrée du conduit débouche dans un ensemble de collecte éolien, qui comprend, de préférence, une pente de terre s'étendant en partie vers le bas, telle qu'un versant ou une levée de terre. L'ensemble de collecte éolien peut comprendre une paire de collecteurs latéraux, tels que des voiles, qui flanquent l'extrémité d'entrée du conduit. Un collecteur supérieur, analogue à un spinnaker, peut être compris au-dessus de l'arbre et entre les voiles de flanc. Les voiles de flanc sont, de préférence, rétractables et peuvent être commandées hydrauliquement. Ainsi, l'ensemble de collecte éolien formé par le spinnaker au-dessus, la pente de terre au-dessous et les voiles latérales flanquant l'entrée, sert à collecter le vent et à le canaliser dans le conduit. Des générateurs couplés aux turbines sont électriquement connectés à une centrale ou à une autre installation électrique en ou hors du réseau.
