Description

FUEL EFFICIENT SELF POWERED GENERATOR

FIELD OF INVENTION

The present invention relates to the field of Electrical Engineering. More specifically the present invention is directed to a fuel efficient self- powered generator. BACKGROUND OF THE INVENTION

Natural hydrocarbon fuels have taken millions of years to form and today, we are using them at a speed much higher than their formation rate. This is an indication that very soon we shall be left with almost negligible natural fuels such as petroleum and diesel. Therefore all over the world, a lot of work is being done to develop engines which use minimal energy or to develop alternative resources for energy generation. Use of vehicles with a substitution of fuel or raw material in the form of bio gas or mixed fuels is being explored with considerable success. Power generation technologies are being developed by using solar, wind, hydro and nuclear energy for generating electricity. Steam turbines are used in industries to generate own power .Solar energy based technologies (solar voltaic cells, solar panels are being used for areas such as for lighting, communications, solar heating etc.) to reduce the dependence on hydrocarbon fuels.

Home power generation: This concept which is being explored so that own home can be powered using alternative resources. This kind of systems can reduce the load of Government as it is the sole provider of electricity in homes. There are many possible means to achieve this objective.

1. Solar power solution- the rooftop of the home is so designed that it can integrate the solar panels which can be used to generate electricity sufficient for a household need.

2. Wind Turbine solution: Regions where strong winds blow are suitable for wind power generation. Wind turbines are installed at the rooftop or in the ground adjacent to home and the energy can be harnessed to provide electricity to the household.

3. Micro CHP solution'. In a micro CHP a fuel source such as natural gas is used to generate electricity, and the excess heat from that operation is used to heat a home and in some cases water as well. The efficiency of converting fuel to useful energy may be as high as 90 percent. 4. Fuel Cell solution: A variation on the micro CHP, fuel-cell technology can be used to generate electricity and heat. It converts natural gas into locally generated electricity and heat, while significantly reducing carbon dioxide (C0₂) and energy costs. The fuel cell uses a proton exchange membrane to convert natural gas into hydrogen. Then an electrochemical converts the hydrogen to electricity. The natural gas does not burn, so there is a dramatic reduction in pollutants and greenhouse gases. The electricity flows through an inverter to power the home, and the excess feeds into the electrical grid. Heat produced in the cycle is transferred through a system for home and water heating.

5. Flywheels solution: Super flywheels store kinetic energy in a high speed rotating drum which forms the rotor of a motor generator. When surplus electrical energy is available it is used to speed up the drum. When the energy is needed the drum provides it by driving the generator. Modern high energy flywheels use composite rotors made with carbon-fiber materials. The rotors have a very high strength-to-density ratio, and rotate at speeds up to 100,000 rpm in a vacuum chamber to minimize aerodynamic losses. The use of superconducting electromagnetic bearings can virtually eliminate energy losses through friction.

We limit our present application to the power generating systems using flywheels only.

As per the data available in free public domain (Ref: http://www.mpoweruk.com/alternatives.html), a one foot diameter flywheel, one foot in length, weighing 23 pounds spinning at 100,000 rpm can store 3 kWh of energy. However at this rotational speed the surface speed at the rim of the flywheel will be 3570 mph. The tensile strength of material used for the flywheel rim must be over 500,000 psi to stop the rotor from flying apart.

A flywheel storage plant for grid power storage with a capacity of 5MWh, providing a power output of 20 MW for over 15 minutes has been installed at a Beacon Power plant in New York and other large installations are in the pipeline.

The energy stored in a flywheel is given by the following formula

E = ½ IG)2

Where I is the moment of inertia of the flywheel (ability of an object to resist changes in its rotational velocity) and ω is its rotational velocity (radians/second). The moment of inertia is given by

I = k r 2

Where M is the mass of the flywheel, r its radius and k is its inertial constant,

k depends on the shape of the rotating object. For a flywheel loaded at rim such as a bicycle wheel or hollow cylinder rotating on its axis, k = 1, for a solid disk of uniform thickness or a solid cylinder, k = ½.

Flywheels are preferred over conventional batteries in many applications because of the benefits of being lesser in weight than batteries, have long life, can generate more usable power and need fewer regulators. They do not need to be charged time and again.

CURRENTLY AVAILABLE FLYWHEEL BASED POWER GENERATION SYSTEMS

There are many systems which are being discussed at various forums worldwide comprising of power generation mechanisms using flywheels. Some of such systems are commercially available in the market under various brands. Some of the web links which provide videos of self- powered generating systems are as below: http://peswiki.eom/index.php/Image:Valy-Valentin_QMoGen_complete_400.jpg http://peswiki.eom/index.php/Directory:Jaime_Inostroza%27s_QMoGen http://peswiki.com/index.php/Directory:Motor-Generator_Self- Looped_with_Usable_Energy_Left_Over An American called Jim Watson built a version which was twenty feet (6 meters) long. It was not only self-powered, but generated 12 kilowatts of excess electrical power.

(Prior art Fig 1)

An Australian called Chas Campbell, discovered the same effect. He found that if he used an AC motor plugged into the mains, that it was possible to get more work done that the amount it takes to drive the motor.

He used his motor to drive a series of shafts, one of which has a heavy flywheel mounted on it. The final shaft drives a standard electrical generator and Chas found that he could power electrical equipment from that generator, electrical mains equipment which required greater current that his mains-driven motor did.

Chas then took it one stage further and when the system was running at full speed, he switched his mains motor over from the wall socket to his own generator. The system continued to run, powering itself and driving other equipment as well.

(Prior art Fig 2 and 3)

(Ref: http:/ /www. free-energy-info, co. uk/Chapt4. html)

However either these suffer from the limitation of not being practically viable and remain at conceptual stage only or the power generated is lesser than complete household electricity requirement. Harnessing of kinetic energy generated by rotating flywheel is not an easy task.

KEY POINTS OF USING FLYWHEELS FOR ENERGY GENERATION:

1. Material of flywheel- Since the flywheels rotate at high speed, high density material is required to make flywheel. But a higher density means that higher centrifugal force is created at the rim of the flywheel which may lead to breaking off the flywheel into pieces when rotated at a high speed. At higher speed, breaking off of the flywheel may result in a dangerous situation.

Therefore the trade- off between the speed and the energy being generated has to be there and thus choice of material having optimum density is required.

Steel was used earlier but now light weight flywheels are made of composite materials as KEVLAR. Now the speed may range upto 60,000 rpm in an ideal situation.

2. Losses due to friction- Since the flywheels are being used to generate energy some of their moving parts are in contact with another hardware thereby generating friction and heat. Lesser the losses due to friction, better is the energy output. To achieve this, now a days electromagnetic bearing are being used and also flywheels are being enclosed in vacuum to reduce the drag forces coming into play while rotating. 3. Cost considerations- Since the material choice of a flywheel is very critical, composite materials being used today are quite costly although are light weight. Therefore, it becomes difficult to use the flywheel technology commonly to generate electricity.

4. Power Quality Considerations- Good quality power output means a constant and uninterrupted electrical output of a set frequency and voltage. In other words, there should be no fluctuations in both these parameters. The amount of energy stored in an FES device mainly depends on the angular velocity of the rotor and therefore efficiency in terms of electronics, bearings and flywheel drag is important.

Limitations of existing flywheel based power generating systems: Although a lot of efforts are being put in to prepare such systems which can generate free energy by means of flywheels. All these existing systems seem to be short lived or the efficiency in terms of power output is not as assumed. No such system is commercially available which can be installed at home to generate power which should be sufficient for a household use. Quality of power is also a big consideration as the available systems duly exhibit the power generation capability but no mention is there for maintaining the quality of generated power in existing systems. No measures are disclosed to regulate the frequency or the output voltage.

SOLUTION PROPOSED BY THE PRESENT INVENTOR

The present invention discloses a super fuel efficient power generator which consumes minimal amount of fuel but generates large amounts of power. Same has been achieved by use of rotating heavy circular flywheels, which once set into motion, gather momentum and keep rotating with minimal force, generating large amounts of electricity in a low-cost, efficient and sustained manner. The generator comprises a fuel storage tank connected to an engine which when switched on, starts rotating the heavy flywheels linked to each other by means of gears, pulleys and belts. The movement of flywheels powers a rotating electromagnet of an alternator (Generator unit) which generates electric power and the same is conveyed to a transformer. The output of transformer is used for light loads such as household electricity requirements. In parallel, transformer in turn is connected to an online voltage regulation and stabilization unit, which acts as a 'power storage' unit as well as regulates the output power in terms of frequency and voltage stabilization. The system then switches ON a motor through a starter. Gear box needs to be detached manually from the engine at this point. THERE IS NO NEED FOR FURTHER CONSUMPTION OF ANY KIND OF FUEL. The output shaft of gear box is now rotated with the help of another flywheel which is being rotated using motor and a set of transmission belts and a pulley.

As a result, the complete unit starts working as a free energy device which can now run on NO natural fuel. The system is capable of working continuously for about 6-7 hours after which it can be forced stopped so that maintenance and routine checking of the components can be carried out as the system is rotating the flywheels at a very high speed and chances of wear and tear are always there.

The complete generator can work for long periods of time, with very minimal utilization of fuel i.e. it is a super fuel efficient power generator.

Quality of output power is maintained by using an online voltage regulation and stabilization unit which comprises a rectifier and inverter circuit along with a battery bank with 38 batteries of 12 V, 42 AH specification.

DETAILED DESCRIPTION OF THE INVENTION

Normally, a flywheel is an electromechanical device that couples a motor/ generator with a rotating mass to store energy for short durations. The motor or generator draws the power from the grid or it can get started with the help of alternative fuels. Once started, the motor is utilized to drive the rotor of the flywheel. Kinetic energy stored in the rotor is transformed to DC electric energy by the generator and the energy is delivered at a constant frequency and voltage through an inverter and a control system.

Flywheel absorbs mechanical energy by increasing its angular velocity and delivers the stored energy by decreasing its velocity. In most cases, a power converter is used to drive the electric machine to provide a wider operating range. Stored energy depends on the moment of inertia of rotor and square of rotational velocity of the flywheel. This stored energy can then be harnessed by the generator when there is a demand for an electrical current and in turn the flywheel slows down.

Moment of inertia (J) depends on the radius, mass, and height (length) of the rotor. The rotor can be modelled as a rotating hollow cylinder. The kinetic energy T stored is given by 2 2 1 T = Jo (4) Where J is polar moment of inertia about axis of rotation and ω is the angular velocity. The energy storage capability of flywheels can be improved either by increasing the moment of inertia of flywheel or by turning it at higher rotational velocities, or both. (Ref: Gupta et al. / International Journal of Engineering, Science and Technology, Vol. 3, No. 1, 2011, pp. 289-297) The basic concept of flywheel as disclosed above is best utilized by the present inventor who discloses a super fuel efficient power generator which consumes minimal amount of fuel but generates large amounts of power. Same has been achieved by use of rotating heavy circular flywheels, which once set into motion, gather momentum and keep rotating with minimal force, generating large amounts of electricity in a low-cost, efficient and sustained manner. The generator comprises a fuel storage tank connected to a motor which when switched on starts rotating the heavy flywheels linked to each other by means of gears, pulleys and belts. The movement of flywheels powers an alternator which generates electric power and same is conveyed to a transformer. The transformer in turn is connected to an online voltage regulation and stabilization unit, which acts as a 'power storage' and conveys the regulated and stabilized power to an electric motor which rotates yet another flywheel. The gear box is cut off manually from the engine now and the third flywheel keeps on rotating the output shaft of gear box which keeps on performing further function as it is without engine now. Further need for any fuel is totally eliminated. As a result, the power generator can work for long periods of time, with very minimal utilization of fuel i.e. it is a super fuel efficient power generator.

The complete system needs the speed of flywheels to be achieved as per the requirements. This speed usually gets dampened due to many effects such as air friction and loading due to output power being consumed. The inventor has put in considerable effort to calculate the sizes of various pulleys so that the final RPM at the alternator end are maintained to 1512 rpm always.

The ratios of pulleys and the speed achieved at output end of each pulley are as illustrated below:

S.No. Location of pulleys Input speed in Ratio of pulley Output speed in rpm size rpm

COMPLETE PROCESS OF POWER GENERATION USING THE PRESENT INVENTION a. The system is started with the help of an engine (EG) by putting a small amount of diesel of about 70 -100 ml. b. Transmission belts attached to engine (EG) through pulley PI at one end and pulley P2 at the other end , drive the gear box (GB ) which after putting third gear, produces 1260 rpm rotational speed at shaft output end. c. Pulley P3 attached to output of gear box (GB) is connected to pulley P5 through transmission belts and rotates the first heavy flywheel (HW1) at a rotational speed of 1512 rpm. d. Pulley P5 connected to pulley P6 which is further connected to pulley P7. Pulley P7 rotates at a speed of 3024 rpm. This rotational speed is transferred to flywheel 2 (HW2) which contains weights inside it to provide inertia of motion to the wheel. e. A pulley P8 fitted at the other end of Shaft of Flywheel 2 (HW2) is connected to pulley P9 through transmission belts. f. Pulley P9 rotates at a speed of 1512 rpm which is the required rotational speed of the alternator to which pulley P9 is connected. g. The three phase alternator (AL) produces an output power of 35 Kw with a frequency in the range of 50 to 51 Hz and voltage up to 440 V which is a normally acceptable range. h. This output power is further passed through a transformer which acts as a stabilization unit in case of any fluctuation in the output of alternator due to any reason. We can step up or step down the voltage or keep it at the same value depending on the selected setting of the transformer. i. Household lighting load is connected to the output of transformer. j. The output of this transformer is further connected to a Regulation and stabilization unit (RSU) consisting of an AC to DC rectifier, an inverter circuit along with a Battery Bank. This regulated and stabilized output power is fed to motor M through starter (S) which starts rotating the shaft at its output end at a speed of 1440 rpm. k. Output shaft of Motor M starts rotating the flywheel 3 (HW3) at a speed of 1440 rpm. Pulley P10 connected to P4 through transmission belts can further produce the desired rotational speed of 1260rpm to the output shaft of the gear box. At this stage, engine (EG) is CUT OFF by taking the clutch to neutral position. No further fuel consumption is required. Pulley P4 successfully rotates pulley P3 which further rotates the flywheel 1 (HW1) and so on.

In order to stop the system, one has to forcibly switch off the starter (S) of the motor (M) so that no rotation is possible for the third flywheel (HW3) which is finally driving the complete generator.

The generator can work indefinitely under ideal conditions but it is recommended to force shut down as the mechanical parts are rotating at a high speed which might result in wear and tear. Regular maintenance has to be done. TESTING OF PRESENT INVENTION

The present invention is already working in model form. The power output quality is up to Indian standards. No frequency or voltage variation is seen. Digital Tachometers, voltmeters and Ammeters are duly taken in line and power monitoring is done in a proper manner.

EMBODIMENTS In another embodiment of the present invention, rating of the self- powered generator can be appropriately increased or decreased, once the basic concept is understood. It is pertinent to mention here that the dimensions mentioned in the application are by way of illustration and example only and are not restricting. Power generation of any capacity can be achieved by changing the ratio of sizes of various pulleys, rating of the alternator and motor.

In yet another embodiment, power generation can also be enhanced without change of physical size of the self- powered generator by using multiple generator units linked together. This offers the technical advantage of ease of commercial manufacture/industrial production, because inventories for different parts and sizes are eliminated, as same sized units are being linked together.

Motor Starter for motor with inbuilt battery bank Novelty: The novelty of the present invention lies in developing a self- powered engine that makes use of a small quantity of fuel and once ignited automatically powers itself for further working. Already available systems did disclose a flywheel based energy generating mechanisms but none of them has worked on STABILIZING of output power which is highly required for the self- powered systems to be actually commercially feasible. The present inventor has duly taken care of this aspect. So the generator of the present invention is self- powered as well as stabilized output energy generator unit.

Inventive step: The inventor has achieved the novelty by carefully selecting specific ratios of pulleys at various points so that the rpm of the alternator are maintained constant. If the alternator keeps moving at a fixed speed, the output power quality in terms of frequency of voltage generated will remain constant.

The inventor has put in considerable effort to stabilize and regulate the output power so that quality of power produced is best and no fluctuations/ ripples / noises are seen at the output end. He has converted the AC voltage to DC voltage thereby eliminating any unwanted spurious voltages. Further the DC voltage which is now pure voltage is fed to battery bank which keeps the batteries in a charged position always. The same DC voltage is again converted to pure AC using an inverter circuit which now is being given to starter of the motor M further responsible for rotating the flywheels in the generator. Since the Starter is getting PURE AC generated as a result of inverting pure DC, it will not have any fluctuations. Motor will thereby run at a constant speed of 1440 rpm further driving flywheel 3 at a constant speed. Therefore, the complete system is now running at constant speeds ideally.

Due care has been taken by the inventor to address the issue of speed dampening of flywheel based generators. He has put in calculated weights at two locations in Flywheel 2 so that it gets moment of inertia and keeps rotating at a fixed speed. He has also used battery bank to replenish loss of power if any due to overloading of the system.

So in totality, the inventor has developed a workable and feasible generator for power needs which consumes negligible fuel and generates high quality output power.

Industrial Application: The present invention finds huge industrial application as the whole world is looking for alternative fuels and alternative methods to generate electricity. Natural resources of petroleum are fast depleting and this kind of generator can be installed in every household so that the household power is taken care of by the individuals. System is a breakthrough in the field of energy harnessing and green energy.

Since it can be manufactured at an industrial scale and has application in society, it has inherent industrial application. In the preceding description, the invention is described with reference to exemplary flow charts thereof. Various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the claims. The specification and drawings are accordingly, to be regarded in an illustrative rather than a restrictive sense. Thus without analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.

Pulley P3 attached to output of gear box (GB) is connected to pulley P5 through transmission belts and rotates the first heavy flywheel (HW1) at a rotational speed of 1512 rpm; d. Pulley P5 connected to pulley P6 which is further connected to pulley P7 which rotates at a speed of 3024 rpm e. This rotational speed is transferred to flywheel 2 (HW2) which contains weights inside it to provide inertia of motion to the wheel; f. Pulley P8 fitted at the other end of Shaft of Flywheel 2 (HW2) is connected to pulley P9 through transmission belts and Pulley P9 rotates at a speed of 1512 rpm which is the required rotational speed of the alternator to which pulley P9 is connected; g. The three phase alternator (AL) produces an output power of 35 Kw with a frequency in the range of 50 to 51 Hz and voltage up to 440 V which is a normally acceptable range; h. This output power is further passed through a transformer which acts as a stabilization unit in case of any fluctuation in the output of alternator due to any reason; i. Household lighting load is connected to the output of transformer; j. The output of this transformer is further connected to Regulation and stabilization unit (RSU) from where-regulated and stabilized output power is fed to motor (M) through starter (S) which starts rotating the shaft at its output end at a speed of 1440 rpm; k. Output shaft of Motor (M) starts rotating the flywheel 3 (HW3) at a speed of 1440 rpm;

1. Pulley P10 connected to P4 through transmission belts can further produce the desired rotational speed of 1260 rpm to the output shaft of the gear box (GB), engine (EG) is CUT OFF by taking the clutch to neutral position and no further fuel consumption is required; m. Pulley P4 successfully rotates pulley P3 which further rotates the flywheel 1 (HWl) and so on.

4. The fuel efficient self- powered generator as claimed in claim 1 WHEREIN in order to stop the system, one has to forcibly switch off the starter (S) of the motor (M) so that no rotation is possible for the third flywheel (HW3) which is finally driving the complete generator.

5. The regulation and stabilization unit (RSU) of the fuel efficient self- powered generator as claimed in claim 1 WHEREIN the same consists of an AC to DC rectifier, an inverter circuit along with a Battery Bank.

6. The fuel efficient self- powered generator as claimed in claim 1 WHEREIN the regulation and stabilization unit (RSU) works as follows:

- AC voltage is converted to DC voltage thereby eliminating any unwanted spurious voltages;

- DC voltage which is now pure voltage is fed to battery bank which keeps the batteries in a charged position always;

- The same DC voltage is again converted to PURE AC using an inverter circuit;

- This PURE AC is fed to starter (S) of the motor (M) which runs at a constant speed of 1440 rpm due to no fluctuations in PURE AC ;

Motor (M) further drives flywheel 3 at a constant speed;

The complete system is now running at constant speeds of all flywheels (HWl, HW2 and HW3) thereby three phase alternator (AL) produces a regulated and stabilized output power.

7. The fuel efficient self- powered generator as claimed in claim 1 WHEREIN real time input and output power quality monitoring is done using digital Tachometers, Voltmeters and Ammeters.
