BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to an elevator electrical power system and, more particularly, the invention relates to an elevator electrical power system for co-generating electrical power in buildings by converting the existing mechanisms of freight and passenger elevators into electrical generators.

2. Description of the Prior Art

The current scenario of energy production across the globe has its intrinsic problems of air pollution from all the fossils we burn, or the eco disturbance caused by the construction of dams across rivers which uproot large number of people and submerge large amounts of land which is many a times fertile and cultivable, having so much water all the time also creates problems. Nuclear energy again has its problems of waste disposal; Oil on other hand is limited in nature. Alternative sources also have its complexities like dependence on sun, wind, water tides. We have to produce energy by these means wherever they are available and then transmitted which also adds to the cost. We have a great imbalance as far as electricity production and distribution is concerned. If we could produce electricity at our discretion with a system which could be constructed close to the actual use of electricity without dependency on nature or adding to air pollution or any eco hazard, we could say we have achieved a milestone in devising a new method to produce electricity.

The proposed system is similar to the system used in dams to produce electricity, but in our case we do not have to build reservoirs for water as we do not depend on water. Hence we are independent of nature, we are harnessing the continuous flow of man made vehicles across the world. These vehicles play the role of falling water in dams which is dropped from a height to interact with the system to rotate generators which produce electricity.

SUMMARY

The present invention is an electrical power system for generating electrical power in a building. The building has an elevator with the elevator having at least one elevator car and the at least one elevator car within an elevator shaft. The electrical power system comprises at least one magnet counterweight connected to the at least one elevator car and at least one coil mounted within the elevator shaft. The at least one magnet counterweight moves in a downward direction as the at least one elevator car moves in an upward direction and the at least one magnet counterweight moves in an upward direction as the at least one elevator car moves in a downward direction. The magnet counterweight passes through the at least one coil thereby generating electrical current.

In addition, the present invention includes an electrical power system for generating electrical power by passing a moving object by a stationary object. The electrical power system comprises a plurality of magnet counterweights connected in series to the moving object and a plurality of coils mounted to the stationary object. The magnet counterweights are mounted to the moving object passes through the coils mounted to the stationary object thereby generating electrical current.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated in FIGS. 1-5, the present invention is an elevator electrical power system, indicated generally at 10, for co-generating electrical power in buildings by converting the existing mechanisms of freight and passenger elevators into electrical generators. The elevator electrical power system 10 of the present invention takes advantage of a basic fact of elevators, i.e., that the cars go up and down by a cable-and-pulley system, a counterweight going down as its car goes up, and going up as its car goes down, to function as follows:

The elevator counterweights of the elevator electrical power system 10 of the present invention are a plurality of powerful permanent magnets 12 or electromagnets; and these magnets 12, borne by cables which run over pulleys to counterbalance the elevator cars, will move up and down through a coil 14. In a preferred embodiment, the coil 14 consists of wound copper wire positioned in a stationary manner, perhaps a guide rail of a tube surrounding the elevator/counterweight magnets cable and secured to the frame of the building. As the elevator moves up, the magnet counterweights move down, passing through the coils (producing an electrical current) when the elevator moves down, the magnet counterweights move up passing through the coils producing an electrical current. Basically, as the magnetic counterweight passes through the metallic coil 14, electrical current will be generated.

The current will be a pulse of Alternating Current (AC), and may be used to augment a building's existing AC power supply. Also, if converted to Direct Current (through the use of a power rectifier), the electricity generated by the elevator electrical power system 10 can be used to charge storage batteries, be stored in condensers, or used directly to applications. The amount of electricity recovered from the elevator electrical power system 10 will be determined by the size of the coils and magnets, the number of coils and magnets, the speed of the elevator, and the space available.

The harnessed energy from the elevator electrical power system 10 of the present invention can be used to power the building, or can be redistributed to power specified areas, or the remainder of the building. The size and weight of the magnet 12 will be determined by the elevator size and capacity. The shape of the coil and counter weight (magnet 12) will be determined by the space available. The number and size of the coils will be determined by the demand for electricity. A permanent magnet 12, for fast moving elevators, or a variable powered, electro magnet can be used on both slow and fast moving elevators. By using flexible magnets 12, the elevator electrical power system 10 works anywhere conveyor belts are used, such as in manufacturing plants, airports, and more. The flexible magnets can be either attached to the conveyor belt or attached to a separate system driven by the same system that drives the conveyor belt. These magnets will either pass over or through the coils that are mounted on or in the conveyor belt frame thereby producing an electric current. The amount of electric power produced will be determined by the number of magnets and coils in the systems. The amount of power will also be determined by the size and speed of the magnets passing through or over the coils. As a consideration, a hydraulic version of the elevator can be constructed.

The elevator electrical power system 10 of the present invention harnesses, with a magnet 12 and coil system 14, the energy created by a moving elevator and redirects the energy as a potential alternative, or con-generation system that powers either the entire building, or specified areas of the building. The elevator electrical power system 10 can providing “green” energy to the building or dwelling in which it is used. The elevator electrical power system 10 not only helps save the environment, but also saves the user or building owner money in power costs.

The foregoing exemplary descriptions and the illustrative preferred embodiments of the present invention have been explained in the drawings and described in detail, with varying modifications and alternative embodiments being taught. While the invention has been so shown, described and illustrated, it should be understood by those skilled in the art that equivalent changes in form and detail may be made therein without departing from the true spirit and scope of the invention, and that the scope of the present invention is to be limited only to the claims except as precluded by the prior art. Moreover, the invention as disclosed herein may be suitably practiced in the absence of the specific elements which are disclosed herein.
