AN APPARATUS FOR GENERATING AN ELECTRICAL ENERGY

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to and claims priority from U.S. Provisional Patent Application Serial No. 60/567,720 filed on May 3, 2004.

FIELD OF THE INVENTION

The present invention relates, in general, to an apparatus for generating an electrical energy and, more particularly, this invention relates to an apparatus for generating an electrical energy which is combustion free and, yet more particularly, the instant invention relates to an apparatus for generating an electrical energy which is sufficient to power an electric vehicle.

BACKGROUND OF THE INVENTION

As is generally well known an internal combustion devices which are widely used in transportation, industrial and home applications place great demand on fossil fuels and produce environmentally harmful pollution.

Efforts have been made, particularly in automotive applications, to replace such internal combustion devices with alternative systems capable of generating energy to power automotive vehicles. Specifically, electric and gas-electric hybrid vehicles have been lately available in limited quantities from major automotive manufacturers.

Electric vehicles have been noted for being more environmentally friendly than conventional internal combustion engine vehicles. Electric engines are several times more efficient than internal combustion engine because they are not limited by heat differential considerations and have no significant friction creating sliding mechanisms.

Generally, available electric vehicles are powered by either electrical batteries and fuels cells. Strictly solar powered electric cars are used only for technology proven races.

The main problem with battery electric vehicles is their limited range in comparison with gasoline powered vehicles and the limited life due to low number of charge–discharge cycles provided before battery replacement is required which also is a subject to environmental disposal issues. Additional problems are related to high costs associated with battery recharging and battery storage space requirements.

It is well known that fuel cell is an electrochemical cell in which the energy of a reaction between a fuel, such as liquid hydrogen, and an oxidant, such as liquid oxygen, is converted directly and continuously into electrical energy. Electric cars operated on fuel cells require as much as four times more energy per unit distance than an electric car when hydrogen production energy is included and presently require expensive membranes manufactured from platinum and other rare metals.

Hybrid vehicles which use an electric engine and grid-rechargeable batteries for acceleration and slow speed driving, with the ability to switch to gasoline power for cruising address the range problem associated with an electric vehicle and improve fuel efficiency of internal combustion engine vehicles. However, these hybrid vehicles are disadvantaged by both environmental pollution issues and high life cycle cost of electric batteries.

Therefore, there is a need for an environmentally friendly apparatus capable of generating an electrical energy which is inexpensive to operate and maintain.

SUMMARY OF THE INVENTION

The invention provides an apparatus for apparatus for generating an electrical energy. Such apparatus includes an electrical generator coupled to one end of a rotating shaft and a flywheel coupled to other end of the shaft. The flywheel has a plurality of blade members disposed on an outer surface thereof. An electric fluid pump generates a flow of fluid under pressure which is directed onto the blade members causing rotation of the flywheel and subsequent rotation of the shaft. The shaft rotation is received by the electrical generator and converted into the electrical energy. The preferred fluid is a liquid. A reservoir is provided to collect the fluid from the flywheel and return such fluid to the fluid pump thus providing for a recirculating operation and further providing for a substantially pollution free operation of the apparatus. An electrical battery is provided to start operation of the fluid pump and initiate rotation of the flywheel and the shaft until sufficient energy is provided by the electrical generator to sustain continuous pump operation. A transformer is used to convert the voltage from the generator into a battery voltage thus providing for battery recharging from the generator. The electrical prime mover of the fluid pump may be configured with a dual winding to receive both generator voltage and a battery voltage or an inverter may be provided to invert battery voltage to generator voltage in which case the electrical prime mover is configured with a single winding. A sun gear is coupled to the flywheel and the shaft for multiplying torque generated by the rotating flywheel. A plurality of rotating disk members are provided to store a kinetic energy generated by the rotation of the shaft and release such kinetic energy to compensate for surge in energy consumption and balance the performance of the apparatus.

BRIEF DESCRIPTION OF THE VARIOUS

EMBODIMENTS OF THE INVENTION

Prior to proceeding to the more detailed description of the present invention, it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.

Reference is now made, to FIGS. 1-4, wherein there is shown an apparatus, generally designated 10, for generating an electrical energy. Such apparatus 10 comprises a shaft 12 which is attached to a rigid structure such as base 14 preferably with a pair of bearing blocks 16 and bearing block supports 18 so that the shaft 12 is allowed to rotate about the base 14. The preferred orientation of the longitudinal axis of the shaft 12 is horizontal.

Means, generally designated 20, for rotating the shaft 12 is coupled to one end thereof and includes, in a preferred embodiment, a flywheel 22 having one each of a predetermined diameter and a predetermined weight and further having a predetermined plurality of blade members 24 rigidly attached to a surface thereof in a predetermined pattern. There is a fluid means 26 for generating a flow of a fluid 28 under pressure which is delivered to a predetermined portion of the flywheel 22 and directed to engage such predetermined plurality of blade members 24 through the fluid communication means 30 which is an elongated member 30 having an internal passageway 32.

Such fluid 28 may be one of liquid and gaseous and preferably, such fluid 28 is the liquid. The fluid means 26 is therefore a well known fluid pump 26 capable of generating a flow of fluid 28 having one each of a predetermined pressure and a predetermined velocity. The fluid pump 26 is connected to an electric prime mover 34 and operable thereby to generate the fluid flow and fluid pressure.

A reservoir 36 is provided to collect the fluid 28 exiting the engagement with the predetermined plurality of blade members 24 and return such fluid 28 to the fluid pump 26 thus recirculating the fluid 28. Preferably, the flywheel 22, the fluid pump 26 and the reservoir 36 are contained within a housing 38 attached to the base 14.

A generator means 40 is coupled to a distal end of the shaft 12 for generating an electrical energy having one each of a predetermined electrical voltage and a predetermined horsepower upon rotation of the shaft 12. The generator means 40 further has a first electrical power output connected to at least one device (not shown) for using the generated electrical energy.

The first predetermined voltage generated by the electrical generator means 40 may be one of any well known voltages, including but not limited to 110 volts, 220 volts, 440 volts and any combination thereof used in variety of household and industrial applications.

It will be appreciated that, in operation, flow of fluid pressure onto the predetermined plurality of blade members 24 will generate a rotation of the flywheel 22 and subsequently generate a rotation of the shaft 12 wherein the rotation of the shaft 12 will be greater than the rotation of the outer surface of the flywheel 22. The rotation of the flywheel 22 will also generate a predetermined torque applied to the shaft 12 wherein said predetermined torque will be defined by the predetermined weight and rotational speed of the flywheel 22. The rotation of the shaft 12 will be received by a preselected portion of the electrical generator means 40, such as magnet (not shown), enabling generation of the electrical energy by converting a mechanical energy of the rotating shaft 12.

Utilization of the recirculating fluid 28, provides for a substantially pollution free operation of the apparatus 10 of the present invention.

Preferably, the electrical generator means 40 has a second electrical power output connected to the electric prime mover 34 providing electrical energy sufficient to operate such electric prime mover 34. It will be appreciated that such second connection enables self-regenerative operation of the apparatus 10.

To initiate rotation of the flywheel 22 and the shaft 12 from a complete stop condition, the apparatus 12 is adapted with an electrical storage means 42, such as electrical battery 42, capable of providing an electrical energy having a second predetermined voltage and having an electrical connection with the electrical prime mover 38 which is adapted with a second winding means (not shown) to receive such second predetermined voltage.

The apparatus 10 may be also provided with means 44 for recharging such electrical storage means 42 which, in the preferred embodiment, is a transformer means 44 electrically connected intermediate the electrical generator means 40 and the electrical storage means 42 converting the first predetermined voltage generated by the electrical generator means 40 into the second predetermined voltage received by the electrical storage means 42 enabling recharging thereof during rotation of the shaft 12.

It has been found by experimentation that the apparatus 10 of the present invention according to the aforedescribed embodiment is sufficient to generate electrical energy under a steady-state electrical energy draw from at least one device (not shown) connected thereto.

It has also been found that when such electrical energy draw is surged stressing the performance of the apparatus 10 and slowing the rotation of the magnet (not shown) of the electrical generator means 40, the apparatus 10 may be provided with means, generally designated 50 and best shown in FIG. 3, for generating a second predetermined torque applied to the shaft 12, wherein such second predetermined torque is greater than the first predetermined torque generated by the flywheel 22.

Such means 50 includes a first gear means 52 disposed adjacent the flywheel 22 and having a first predetermined portion thereof connected to a rigid structure, a second predetermined portion thereof connected to the flywheel 22 and a third predetermined portion thereof coupled to the shaft 12 for rotation therewith. Preferably, such first gear means 52 is a well known planetary gear set 52, best shown in FIG. 4, having a ring 54 coupled to the flywheel 22, a plurality of planet gears 56 connected to a carrier 58 which is rigidly attached to the base 14 and a sun gear 60 coupled to the shaft 12.

Such planetary gear set 52 increases the torque generated by rotation of the flywheel 22 and delivers such increased torque to the shaft 12.

The means 50 may further include at least one disk member 62 having a predetermined weight which is rigidly attached to a predetermined portion of the shaft 12 for rotation therewith. Such at least one disk member 62 is for storing a kinetic energy generated by the rotation of the shaft 12 and for releasing such kinetic energy during increased electrical draw placed onto the electrical generator means 40 for balancing the performance of the apparatus 10.

Preferably, such at least one disk member 62 is a predetermined plurality of disk members 62 axially aligned and connected therebetween with a second gear means 64 which is a second planetary gear set 64. Advantageously, such second planetary gear set 64 alternate rotational directions of such predetermined plurality of disk members 62 and balance directional distribution of the torque applied to the shaft 12. The shaft 12 in such embodiment will be formed by a predetermined plurality of shaft portions, each axially aligned and supported by the pair of bearing blocks 16 and bearing block supports 18, as best shown in FIG. 3.

Additionally, in applications wherein the rotational speed of the shaft 12 generated by the disk member 62 disposed adjacent to the electrical generator means 40 exceeds the rotational speed required thereby, the apparatus 10 is adapted with a third gear set 66 capable of reducing the rotational speed of the shaft 12.

Alternatively, the rotational speed of the shaft 12 required by the electrical generator means 40 may be provided by regulating the rotational speed of the flywheel 22 which in turn is regulateable by the fluid pressure and velocity generated by the fluid means 28.

At least fluid means 26, prime mover 34, electrical generator means 40 and electrical storage means 42 have an electrical connection with a control means (not shown) provided for controlling operation of the apparatus 10.

Although the present invention has been shown in terms of the flywheel 2 and the fluid means 26 generating the rotation of the shaft 12, it will be apparent to those skilled in the art, that the present invention may be applied to other forms of generating such rotation of the shaft 12. For example, a power transmission means such as belt, gear, chain and the like coupled to the shaft 12 will generate rotation thereof in combination with an independent prime mover. Such prime mover may be electrically driven by the electrical generator means 40 or may be pneumatically or hydraulically driven by a corresponding drive means. Alternatively, a rotary drive means may be directly coupled to the end of the shaft 12.

Furthermore, the means for recharging the electrical storage means 42 may include a second electrical generator means, such as alternator, coupled to the shaft 12 with any well known power transmission means, such as belt, chain and the like, and having an electrical connection with the electrical storage means 42. In operation, the rotation of the shaft 12 will enable the second electrical generator means to generate the second predetermined voltage and recharge the electrical storage means 42.

The electrical storage means 42, such as electrical battery, may be a well known twelve-volt electrical battery currently found in combination with the alternator on any vehicle (not shown) having ground engaging wheels.

Additionally, an inverter 46 may be connected intermediate the prime mover 34 and the electrical storage means 42 for converting the second predetermined voltage generated by the electrical storage means 42 to a first predetermined voltage generated by the electrical generator means 40, thus providing for a simplified construction of the prime mover 34.

Thus, the present invention has been described in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains to make and use the same. It will be understood that variations, modifications, equivalents and substitutions for components of the specifically described embodiments of the invention may be made by those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
