Field of Invention
This invention relates to the field of electricity generation, and is directed to the production of electric power by converting the mechanical weight energy into electrical energy.
Background of the invention
Both the developing and the developed nations face power shortage and this problem will only aggravate in time to come. The need for identifying and generating alternate sources of energy is felt by every one. Considerable effort and research work is going on in this field.
Rapid industrialization and upward movement in standards of living result in increased electricity consumption, which has gone beyond all calculations and expectations. Fuel and other natural resources for generating power is rapidly depicting and the need for supplementing and augmenting the existing supply of power and energy is felt by everyone. Alternate sources of energy have been considered and a lot of R & D goes on in this area.
It is a well known fact that electricity is generated by driving a turbine engine, water wheel or such similar machine of electricity generator or a device that converts mechanical or chemical energy to electrical energy. Steam turbines, internal combustion turbines, gas combustion turbines, water turbines and wind turbines are the most common means to generate electricity. A turbine converts the kinetic energy of a moving fluid, liquid or gas, to mechanical energy. Steam turbines have a series of blades mounted on a shaft against which steam is forced thus rotating the shaft connected to the generator. In a fossil fueled steam turbine, the fuel is burned in a furnace to heat water in a boiler to produce steam.
Coal, petroleum and natural gas are burned in large furnaces to heat water to make steam that in turn pushes on the blades of the turbine. Nuclear power is another means by which steam is produced by heating water through a process called nuclear fission.
Hydro power generation is a process in which flowing water is used to spin a turbine connected to a generator. Geothermal power, Solar power, wind power and biomass power are the other alternative sources of electricity production.
In order to boost the existing electric supply, there is a need for developing a simple but effective electricity generator which can convert mechanical work force, which otherwise goes unutilized, to eletricity.
Object of the invention:
An object of the present invention is to produce electricity wherein weight energy is being converted into electrical energy. The body weight of human beings and moving vehicles are converted into mechanical energy which in turn is converted into electrical energy.
The basic idea of electricity production is a coil of wire rotating with in a magnetic field. Interrupting the magnetic field produces a charge caused by the electron movement. This is called electricity. To make the coil rotate different systems and means are used in prior art.
According to the present invention, weight energy is utilized to rotate a turbine which is connected to a rotatable member of a magnet and coil assembly thereby electricity is generated. The generator of the present invention converts mechanical energy, which would otherwise have gone untapped, into electrical energy.
If the generator of the present invention is kept at homes over the 'Veranda' or a common walking place, every time a man walks on the top plate, electricity is generated. At home, a walking corridor can be created with at least 100 such units. Each plate is made to be of 1 feet x 1 feet size. The walking corridor could be of the size 5 feet x 20 feet. So there are 100 numbers of electric generation units. Approximately if a person walks over this corridor for 30 minutes he will exercise pressure on the top plate at least 5000 times and thus producing electricity.
Another object of the present invention is to provide an electricity generation unit in miniature size, that could be fitted into the sole of a shoe, to be used as a charger for the cell phone, hearing aid walkman, cardiac pace maker or any other wearable electrical device.
Yet another object of the invention is to provide an electricity generation unit in a massive size, that could be placed under the roads and the vehicle that passes on the road may exert pressure from which massive quantities of electricity generation is possible.
The electricity generator of the present invention can make every shoe, every home, every road and every public place as the power production unit. Summary of the invention:
According to the present invention, weight energy is utilized to rotate a turbine, which is connected to a rotatable member of a magnet and coil assembly with a help of a first shaft. In one embodiment, the magnet is static and the coil is made to rotate by the turbine. In another embodiment, the coil is static and the magnet is made to rotate by the turbine. A second shaft is attached to a spring loaded top plate and its free end is constructed in such a manner so as to engage the teeth of the turbine. In one embodiment the second shaft can be a curved shaft with corrugation in the inside edge at the free end to engage the teeth of the turbine. In another embodiment, the second shaft can be a straight shaft with pointed tip.
Any pressure given on the top plate will cause the second shaft to move downwards thereby rotate the turbine. The first shaft will transmit the rotation of the turbine to a rotatable member of the said assembly thereby electricity is generated. An electrical output circuit is connected to the coil for transmitting the electricity. The top plate is kept in position by a pair of springs and fixed platform placed on either side to prevent it from touching the turbine. Once the pressure is released from the top plate, the top plate moves to the original position. When pressure is exerted, the turbine is made to rotate. By continuous exertion of pressure at the top plate, this mechanism generates electricity and is one of the easiest way of electricity generation. To gain the mechanical advantage, a wheel may be coupled with one or more wheels to give maximum efficiency by attaching to a gear system.
Accordingly the present invention provides an electricity generator for converting mechanical work force into electrical energy, said generator comprising a magnet and a copper coil assembly, one member of said assembly being static and the other being rotatable, said rotatable member is driven by a first shaft which is connected to a toothed turbine; a second shaft extending downwardly from a spring loaded top plate, free end of said second shaft being constructed to engage the teeth of said turbine; and an electrical output circuit connected to said copper coil for carrying the generated electricity, the arrangement being such that exertion of pressure on said top plate actuates the second shaft to rotate the turbine which in turn rotates the rotatable member to convert the mechanical force into electrical energy.

Detailed description of the invention
Figure 1 is a sectional view of the electrical generator of the present invention in accordance with one embodiment. In Figure 1 the magnet 1 is a static magnet and having 2 arms namely North Pole and South Pole. A copper coil which is located inside the magnet is rotatable. A first shaft 4 is attached with the Copper coil. The other end of the first shaft 4 is attached to a turbine or a wheel 5. This wheel 5 has a corrugated edge with teeth all around. A second shaft 6 with a curved & toothed structure extends from a top plate 8. The tooth like projection of the wheel 5 and the second shaft 6 are kept facing each other so as to fix exactly with each other. This arrangement makes the wheel 5 to rotate when the top plate 8 is pressed downwards. A pair of springs 7 is attached at the bottom of the top plate. The springs 7 rest on a platform 9 which is held in position from the floor. An electric circuit 3 is connected to the coil for carrying the generated electricity.
Figure 2 shows the electrical generator incorporated at the floor under the carpet 11. The floor tiles 10 may be preferably of the size 1 ft x 1 ft, the size of the floor tiles may vary according to convenience and size of the corridor (12).
The edges of the tiles may be attached to the rubber headings 18 to prevent water and dust from entering into the generator.
Figure 3 shows the electrical generator of the present invention in its miniature size fitted well into the sole 14 of a shoe 15. All the embodiments are similar except for the size. The size of the wheel 5 can vary from 3mm to 5mm. Accordingly the size of the magnet, coil, and the top plate can vary in size. The embodiments are similar to the description given in Figure 1, except for the size and the support platform for the spring. Here, the support platform extends from the bottom of the sole of the shoe as a rod and supports the springs on either sides of the wheel and magnet. These are bilaterally similar embodiments on either sides of the wheel. The output circuit is connected to the wires at one side of the inner aspect of the sole of the shoe which goes up to the top portion of the shoes opening on one of the sides correspondingly.
The top platform is designed such that it rests beneath the sole of the shoe. The top plate 8 is designed in such a way that it rests beneath the sole sheet of the shoe. The springs rest on the rod 15 which is attached to the bottom layer of the sole. When the top plate is pressed by the heel, electricity is generated. The generated electricity is carried via the channel 16 to the output socket 17. From 17, the electricity could be carried through wires placed with in the pants covered by a cloth sleeve, which goes up to the hip. From there the electricity can be supplied to the cell phone which is placed in the belt pouch. In the similar manner, power supply could be supplied to the walkman, cardiac pacemaker, hearing aid etc.
Figure 4 shows the generator planted under the road next to the speed breaker bump. Here the size of the wheel or the turbine may be of the size 1 meter diameter. Relatively all the other embodiments are enlarged in size. The road 21 has the speed breaker bump 22 and the top plate 8 of the generator is planted next to the speed breaker bump. In this case, the top plate may be of the size of a lorry chassis, approximately 20ft x 6 ft.
Figure 5 shows the speed breaker bump 22 and the generator is fixed before the bump under the road 21. As in figure 4 here also the generator is planted under the road with the top plate 8 corresponding to the top surface of the road 21.
Figure 6 shows the generator planted under the road at a slope. The top plate 8 is corresponding to the surface of the road on the front aspect and the back aspect of the top plate is slightly elevated than the surface of the road. When the spring is pressed the back aspect of the top plate 8 will correspond to the surface ofthe road 21.
Figure 7 shows the incorporation of the generator under the staircase 20 with the top plate 8 built as the sloppy structure and when it is pressed it will come to 180° position.
Figure 8 shows the generator incorporated under the staircase 20 so that the top plate 8 is horizontally placed at 180° and when pressed it will go down and become a downward slope. In Figure 9(a), the generator is place under a treadmill type of steps which will enable the user to climb up and down several times for 30-60 Minutes a day, whereby the user gets the advantage of accomplishing two purposes namely exercising and power generation for his domestic needs. This could be made as a portable unit or constructed with in the houses. Each step 20 is connected to the power generating wheel which in turn is connected to the turbine to rotate the magnet. The centrally placed hand rails helps the elderly people to climb up & down without difficulty. The top step 27 is at the highest level of the treadmill. Fig 9(b) shows the top view of the treadmill type power generator. So, if a person using this power generator goes up and down twice he completes one round of journey. The person can continue to use this treadmill at his convenience.
Figure: 10 shows the generator unit incorporated under the floor and within the wall adjacent to the floor. The wheels are rotated by exerting linear pressure by the human weight on the tiles to which the top plate of the generator is attached. This rotation is transmitted through the chains 23 which in turn is connected to the turbine 5, so any tile when pressed by a person, the weight of the person exerts pressure on the tiles and the turbine 5 is rotated. Thus electricity is generated. Here the wheels under the tiles are of small size and the turbine can be of the size of the wall. The turbine 5 can occupy the whole wall. By making the turbine large the mechanical advantage is obtained and the generator wheel is rotated at a higher speed, thus producing more electricity. A gear system incorporated in between the turbine and the magnet can dramatically increase the number of rotations.
In figure; 11, the generator unit could be placed over the body of a ceiling fan 29. When the ceiling fan is put on, the small wheels provided on top of the body of the ceiling fan 29 over connected through chains and are connected to the turbine 5. This whole unit can be placed within a small compartment. When the turbine 5 rotates it rotates the magnet within the copper coil kept within the compartment and electricity is generated. From here wires could be brought out to connect to the lights and other electrified consumables at home. Thus the rotation of one ceiling fan can provide power supply for few bulbs and few fans at home.
Fig. 12 shows another embodiment of the generator wherein the second shaft can be a straight shaft with a pointed tip. When the top plate is pressed downwards, the tip of the second shaft pushes the teeth of turbine 5 which results in rotation of the turbine.
The above embodiments of the generator of the present invention have similar structures except for the size and they are placed in different locations according to the need. The rubber beading 18 is incorporated in all the places under the tiles under the staircase and on the roads in close association with the top plate to prevent water and dust from entering into the generator.
The drawings are not to the scale and hence the size and measurements can vary from place to place.
In all the arrangements shown above, the top plate 8, when pressed repeatedly keeps the wheel 5 rotating continuously, which makes the coil 2 to rotate with in the magnetic field of the magnet 1. Thereby electric current is generated and the output voltage is received at the circuit 3. With the help of a measuring device 9, the quantity of electricity is measured and utilized as per the requirement. To prevent dust and water from entering into the generator, the floor tiles and the top plates of the road generators could be provided with rubber headings 18 all around their edges. In this kind of electric generator, the body weight of human beings and the weight of the moving vehicles are invested usefully to produce electricity. Every home, every public place where there is human movement, every road with lot of traffic is made a power generating unit. Electricity thus produced, can be used as an additional source of electrical energy if not used as the main source. If done properly and effectively, this kind of electric generators can be made the primary source of electricity which will help the people to be independently producing their electrical needs on their own. The smallest unit of this kind can be utilized as a cell phone charger, and largest such units can be used as massive electrical generators on the national highways.
With this simple generator, every human being walking on the earth can produce electricity and every moving vehicle on earth can contribute to producing electrical energy without effort and expenditure.
In another embodiment, the copper coil can be made static and the magnet can be made to rotate around or within the copper coil as shown in figure 13. This is a walkover generator. This is not portable. If you walk over it or run a vehicle over it, this generator can produce electricity.
Other possibilities of generating power and utilizing the power generated there from are described below:
Home Electric Generator:
At homes, these electrical generators could be constructed at the common hall or corridor where people keep walking. This walking corridor may be of the size 5 feet x 20 feet, thus having approximately 100 mini generators on the corridor. The 100 top plates could be covered with the floor tiles and above that a carpet is spread, which will give a spongy soft feeling while walking over this corridor. In between the tiles there could be space that can attract dust. This could be avoided using rubber headings. Transformers may be used to modulate the electrical energy. Thus a person having a regular walk on this walking corridor will achieve the dual purpose of exercising and producing electricity.
Cell Phone Charger:
Man is using electrically rechargeable devices like cell phone, hearing aid, walkman, cardiac pace makers etc. All these devices need electrical energy for a continuous use. So, by constructing this kind of small electrical generators in the sole of the shoes, one can produce electricity while walking. Spontaneously while walking the batteries of their electrical devices get charged which does not require any additional power supply. This makes life very simple and independent.
Massive Generators:
Every national high way allows the passage of at least 10,000 vehicles per day approximately. If each heavy vehicle with tons of load presses this electrical generator constructed on the roads, they will produce huge quantities of electricity in several kilowatts to megawatts. For every generator, we have to spend money on the fuel. Making use of coal, gas, steam is all very expensive. Constructing thermal power station, nuclear power stations and hydro power stations are very expensive projects. But this fuel free electric generators could be built with a minimum expenditure comparatively. The generator of the present invention is also eco friendly and pollution free.
It will be appreciated by those skilled in art of having the benefit of this disclosure that this invention provides a simple generator.
