       [0004]    1. Field of the Invention 
         [0005]    The present invention relates generally to power generation devices, and in particular to a flywheel generator system and method of generating electricity which conserves electric energy by the use of a series of C-shaped or other shape looped coils positioned around a flywheel with magnets extending from the outer edge of the flywheel passing through the coils to generate electricity and with no magnetic material is the coils there is no resistance created thereby providing more efficient electricity generation. 
         [0006]    2. Description of Related Art including information disclosed under 37 CFR 1.97 and 1.98 
         [0007]    As is known in the prior art, electric generator methods of energy production are based on the principal of electromagnetic induction. The stator of the generator has magnetic material inside of the coil, and when the rotor moves the magnets close to the coil and the magnets are attracted by metal inside of the coil, the metal becomes a magnet itself by magnetic induction, and the impulse of the magnetic field produces electric current in the coil. 
         [0008]    The problem with prior art electric generators is that a rotor with permanent or electric magnets is attracted by magnetic material inside of the coils of the stator to make the rotor spin inside the stator with high magnetic resistance. The more load to the generator the higher the resistance, and more mechanical power must be applied to the rotor of the generator in the order to produce electric energy. 
         [0009]    U.S. Pat. No. 5,341,060, issued Aug. 23, 1994 to Kawamura, claims an engine having a flywheel which has a high peripheral speed even when the engine rotates at a low speed. The flywheel has a plurality of permanent magnets mounted on an outer circumference thereof and having alternately different magnetic poles. A stator is disposed in confronting relation to radially outer ends of the permanent magnets. Electric energy induced by the stator upon rotation of the flywheel is supplied to a rotary electric machine combined with a turbocharger to assist the turbocharger in supplying air under pressure to the engine when the engine rotates at low speed. 
         [0010]    U.S. Pat. No. 3,629,632, issued Dec. 21, 1971 to Loupe, describes a generator for use with a small rotary engine incorporating permanent magnets in its flywheel, the generator being mounted exteriorly of the flywheel and within the flywheel housing, if any is used. The magnets move relative to a stator having a “double-E” configuration with two poles, each of which carry a pair of windings. The windings on each pole are connected in electrical opposition through diodes to supply the desired electrical current. The stator structure is laminated and has preferred physical dimensions. 
         [0011]    U.S. Pat. No. 5,214,333, issued May 25, 1993 to Kawamura, discloses an engine having a flywheel which has a high peripheral speed even when the engine rotates at a low speed. The flywheel has a plurality of permanent magnets mounted on an outer circumference thereof and having alternately different magnetic poles. A stator is disposed in confronting relation to radially outer ends of the permanent magnets. Electric energy induced by the stator upon rotation of the flywheel is supplied to a rotary electric machine combined with a turbocharger to assist the turbocharger in supplying air under pressure to the engine when the engine rotates at low speed. 
         [0012]    U.S. Pat. No. 6,791,225, issued Sep. 14, 2004 to Campbell et al, indicates a flywheel magneto generator having a rotor assembly and a stator assembly. The rotor assembly includes a non-ferromagnetic flywheel and a plurality of magnetic poles that are positioned in spaced relationship around the circumference of the flywheel. The stator assembly includes an E-shaped core with a single magnet mounted on the center leg and coils associated with at least the outer legs. The poles and core may be formed of a bonded iron material. The poles may be joined to the flywheel by press fitting or integral molding, among other methods. 
         [0013]    U.S. Pat. No. 7,132,775, issued Nov. 7, 2006 to Oohashi et al, is for a dynamoelectric stator and a method for the manufacture thereof enabling electrical insulation properties to be improved by forming slot-housed portions with a racetrack-shaped cross section to suppress damage to an electrically-insulating coating arising during mounting of a stator winding to a stator core. The construction is such that the slot-housed portions of the stator winding are formed with the racetrack-shaped cross section, and are housed inside slots so as to line up in single columns in a radial direction with a longitudinal direction of the cross section of the slot-housed portions aligned in a circumferential direction. Thus, because short sides of the slot-housed portions facing inner circumferential side surfaces of the slots form convex curved surfaces, the occurrence of damage to the electrically-insulating coating resulting from rubbing between the short sides of the slot-housed portions and the inner circumferential side surfaces of the slots during insertion of the slot-housed portions into the slots is suppressed, thereby improving electrical insulation properties. 
         [0014]    U.S. Pat. No. 4,460,834, issued Jul. 17, 1984 to Gottfried, provides an uninterruptible power supply to an external load comprising a flywheel generator, a first motor, a standby generator, and a transfer controller. The flywheel generator is adapted to supply energy to the external load. The first motor is drivingly connected to the flywheel generator. The first motor is adapted to be connected to a source of power external to the power system. The standby generator is electrically connected to the first motor. A standby motor is drivingly connected to the standby generator. The transfer controller is adapted to switchably interconnect the first motor to the source of power and to interconnect the standby generator to the first motor. The flywheel generator comprises a flywheel having a vertical axis, a shaft connected to the flywheel, and a synchronous A.C. generator arranged about the shaft. The standby motor is a diesel engine having an electric starter. A voltage regulator is electrically connected about the output of the flywheel generator. 
         [0015]    U.S. Pat. No. 7,126,233, issued Oct. 24, 2006 to Thomas et al, shows a method and apparatus for generating power in a rotating environment without access to the axis of rotation. A non-center engagement generator is implemented within the rotating reference frame of a vehicle wheel. Further, a method and apparatus detect a potential rollover state and prevent occurrence of a rollover state or eliminate a rollover state once attained. 
         [0016]    U.S. Pat. No. 6,891,295, issued May 10, 2005 to Maritomi et al, puts forth a flywheel magneto generator which comprises a rotor having a magnet attached to an outer circumferential side of a flywheel and a stator constructed by winding a generating coil around a core having a magnetic pole portion opposed to a magnetic pole of the rotor, wherein a through hole is formed in a peripheral wall portion of the flywheel, a yoke plate is provided so as to block one end of the through hole which is opened on an inner circumferential side of a peripheral wall portion of the flywheel, the magnet to which a magnet cover is attached is supported on the yoke plate, and one magnetic pole face of the magnet is opposed to the yoke plate. 
         [0017]    What is needed is a more efficient system for generating electricity wherein the coils do not create magnetic resistance.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0030]    In  FIGS. 1-8 , a flywheel electric generator system  20  uses loop shaped coils  4  encircling a spinning flywheel  1  so that a series of mating shaped permanent magnets  5  attached to a disc  6  extending from the outer perimeter of the flywheel  1  with the shaped magnets  5  passing through the mating shaped coil openings  17  and  1   7 A to generate electricity in the coils. 
         [0031]    In  FIGS. 1 and 6 . the flywheel  1  for the flywheel electric generator system  20  comprises a flywheel  1  of substantial mass and thickness pivoting about a center axis  2 . A thin annular disc  6  extends outwardly from an outer perimeter of the flywheel  1 . The annular disc  6  has a thickness substantially less than the flywheel. A series of magnets  5  attached to an outer perimeter of the annular disc  6 . The magnets  5  each having a mating identical peripheral shape. A source of rotational power causes the flywheel  1  to spin. 
         [0032]    In  FIGS. 2-5 ,  7  and  8 , a series of coil loops  4  are attached to a structure separate from the flywheel  1 , positioned in a circular array around the outside of the flywheel  1  out of contact with the flywheel. Each of the coil loops  4  comprises an elongated oval coil winding bent into an open loop configuration with the coil ends  18 A and  18 B of the elongated oval coil windings spaced apart in close proximity to form a coil end space  16  and  16 A facing the flywheel  1  to receive the annular disc  6  spinning within the coil end space  16  and  16 A without contacting the coil ends. The open loop configuration of the coil loop  4  forms an interior loop opening  17  and  17 A mating the outer peripheral shape of each of the magnets  5 , the interior loop opening  17  and  17 A being slightly larger than the peripheral shape of each of the magnets  5  so that the magnets spin around as the attached flywheel  1  spins, with the magnets  5  each passing through all of the coil loops  4  with each rotation of the flywheel without contacting the coil loops. Each of the moving magnets  5  generates a flow of electricity is each of the coil loops  4 . The flow of electricity generated in the coils  4  is transmitted from the coil loops  4  to devices for using and storing the flow of electricity. 
         [0033]    In  FIGS. 7 and 8 , each of the coil loops  4  and  4 A comprises an electrically conductive wire  15  wound around two spaced posts in a multiplicity of windings to form a built up cable in the shape of a closed elongated oval loop with two parallel spaced sides  19  and two semicircular ends  18 A and  18 B which is bent into an open loop coil configuration having the two semicircular ends  18 A and  18 B positioned in close proximity to leave the coil end space  16  and  16 A between the two semicircular ends  18 A and  18 B with the two parallel sides  19  forming two parallel loops around the interior opening  17  and  17 A. 
         [0034]    In  FIGS. 1-7 , each of the coil loops  4  has a circular (or oval) interior opening  17  to form a C-shaped coil loop used with magnets  5  each having a circular (or oval) peripheral shape. 
         [0035]    In  FIG. 8 , each of the coil loops  4  has a rectangular interior opening  17 A for a square shaped coil loop used with magnets  5  each having a rectangular peripheral shape. 
         [0036]    The coil loops  4  may have any of a variety of shapes of interior opening  17  and  17 A for any of a variety of shaped coil loops  4  used with magnets  5  each having any of a variety of mating peripheral shapes. 
         [0037]    In  FIGS. 1 and 6 , the system  20  preferably comprises an electric motor  7  as a rotational force supply communicating with the flywheel  1  for maintaining the rotation of the flywheel  1  at a desired optimum level for efficiency. A means for detecting the flywheel speed of revolution  12 , such as an RPM counter, controls a means for activating the electric motor  7 , such as a time controller  8 , to speed up the flywheel  1  to a desired rotational speed and deactivating the electric motor  7  upon detecting the desired rotational speed so that the flywheel  1  continues to spin by inertia for maximum output of electricity. The combination of speed of revolution of the flywheel  1 , mass of the flywheel, and diameter of flywheel determine the desired rotational speed of the flywheel. 
         [0038]    The flywheel  1  may be connected to a rotor of the electric motor  7  for turning the flywheel. Alternately, the flywheel  1  may be connected to the electric motor  7  through a transmission interface system  13  for spinning the flywheel. 
         [0039]    To generate electric power in the coils by spinning the flywheel, the flywheel  1  may be connected to at least one of the following rotational power sources  9  taken from the list of rotational power sources comprising an electric motor, an electric motor powered from rechargeable batteries  9  preferably with a charge control  10  and wiring  11  connected to a time controller  8  to the electric motor  7  (shown in  FIG. 1 ), an electric motor powered from rechargeable batteries powered by at least one solar panel, an electric motor powered from rechargeable batteries powered by at least one wind generator, an air motor, an air turbine, a wind turbine, an engine, a rotational force source from pressurized air, a rotational force source from pressurized vapor, a rotational force source from pressurized vapor of a liquid gas or other sources of rotational power. 
         [0040]    A vacuum chamber  14 , as shown in  FIG. 6 , may be used for containing the flywheel  1  and the series of coil loops  4  inside of the vacuum chamber to lower air resistance for greater efficiency in generating electricity. 
         [0041]    The center axis  2  of the flywheel may comprise or connect with at least one of the following rotation devices taken from the list of rotation devices comprising bearings  3 , low friction bearings, magnetic bearings, and electromagnetic bearings for minimizing rotational friction for optimum performance of the flywheel. 
         [0042]    A great advantage of using a shaped loop wire coil is that it doesn&#39;t have any magnetic material inside and has a special type of coil winding with the elongated wire winding loop bent into a shaped loop which allows magnets to go through the winding of shaped loop coil itself. Because there is no magnetic material at all in the shaped loop coil, therefore there is no magnetic resistance at all, which allows the magnets to go through shaped loop coil freely, while at the same time electro magnetic induction from the magnets makes the winding of the shaped loop coil produce electric current. The shaped loop coil can have any type of shape of winding. What is most important is that it has a narrow opening in the windings facing the flywheel  1  to allow the disc  6  or other element holding the magnets  5  to fit through the narrow opening and maintain the magnets within the loop opening without touching the loop itself while the magnets  5  spin through all of the loops  4  with the spin of the flywheel  1 . 
         [0043]    In use, the flywheel  1  and flywheel axis  2  can be connected to the rotor of the electric motor  7  directly or it can be connected through a transmission (Interface System)  13  or it can be connected to any other Rotational Force Supply  9  such as (air motor, air or wind turbine any type of engines and other). The electric motor  7  powered from rechargeable batteries  9  or powered from any other Rotational Force Source  9 , such as pressurized air, vapor of liquid nitrogen or other liquid gases and other sources depending on the type of Rotational Force Supply. Rechargeable batteries  9  can be charged from solar panels, wind generators or any other source of energy. The flywheel  1  and loop shaped coils  4  can be located inside of a vacuum chamber  14 , to lower air resistance. 
         [0044]    The electric motor  7  speeds up the flywheel  1  to a desired speed measured by an RPM (Revolutions Per Minute) counter and a time controller  8  and then the flywheel  1  is disconnected from the power from electric motor  7 , and the flywheel  1  continues to spin by inertia force. When the flywheel  1  goes down below a set RPM, the time controller  8  which is connected with the RPM counter  12  turns on the electric motor  7  for several seconds to speed up the flywheel  1  for optimum set RPM. This cycle is constantly repeated to keep the flywheel spinning in diapason of maximum and minimum RPM. The duration of spinning of flywheel  1  is dependant on the speed, mass and diameter of the flywheel. When the flywheel  1  is spinning, the magnets  5  attached to the flywheel  1  or to a separated mounting located on the same axis  2 , going through coils  4  to produce electric current. 
         [0045]    The electric energy from the shaped loop coil flywheel electric generator system of the present invention can be used for different types of applications. It can be used as source of energy for houses, buildings, commercial buildings, factory and other production facilities. It can be used in power plants for towns and cities. It can also be used as a source of energy for land vehicles, marine vehicles, marine platforms and other types of vehicles. 
         [0046]    Also the shaped loop coil flywheel generator of the present invention can be used as a source of energy in space for space stations or space vehicles. Because there is vacuum and no air resistance in space, the present invention can produce energy with high efficiency. And it can be used in many other applications by scaling up or scaling down the size of the device. 
         [0047]    It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and that various modifications may be made thereto without departing from the spirit of the invention as claimed.
