BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to power generation and, more specifically, to a system for generating electricity utilizing continuous reusable energy. 
     The energy generating system of the present invention produces low cost electric power without consumption of limited natural resources, pollution, or greenhouse gas emission, and is independent of wind conditions. In turn, the energy generating system of the present invention provides improved means over existing coal and gas fixed power generation as well as nuclear plants and wind mill farms. 
     The present invention is a system for generating electricity comprising a plurality of towers in communication with a base level conduit housing having a section of smaller diameter containing an air driven turbine connected to a power storage system used to power a generator. 
     The towers are unified at the lower end with a single base enclosure providing means to maximize air speed. The venturi throat with the undershot air wheel is affixed within the single base enclosure. The upper end of each tower can include a venturi like collar to increase air suction. 
     An air compressor or pump is connected to the shaft of the aforementioned under shot air wheel by means of belt and/or gear system. The compressed air is then transferred to a storage tank suitable for high pressure. A plurality of air compressors and/or storage tanks may be utilized to suit power requirements to run the generator. Additionally, a fluid pump(s) may be utilized in lieu of the air compressor(s). 
     The compressed air is released and transferred to the generators whirling wheel providing necessary mechanical energy to turn the generator rotor and in turn, means to convert the mechanical energy into electrical energy. Pressure valves and an automatic controller provide means to regulate air flow between the store tanks and to the generator.

     A wind powered generating device comprises a tube cluster, a collector assembly, and a turbine assembly. The collector assemblies utilize sails that can be rotated to direct wind down through an inlet tube to a central outlet tube. The central outlet tube is narrowed at a portion, and a turbine is mounted at this narrowed portion to take advantage of the Venturi effect that accelerates the air as it passes the turbine. This permits reliable and efficient operation in areas that were not formerly considered windy enough to be economically feasible for the deployment of wind powered generating devices. Alternative embodiments of the invention include mechanisms for dealing with violent weather conditions, a first of which allows excess wind to bleed off beneath and between the sails, and a second which collapses and covers the sail with a protective sheath/sock.
