No. 60/545,383, attorney docket number PVAS0001/MRK, entitled “METHOD AND APPARATUS FOR CONVERTING HUMAN POWER TO ELECTRICAL POWER”, filed Feb. 18, 2004, the entire disclosure of which is incorporated herein in full by reference as if stated in full herein.
- The field of the present invention is mechanical power converters, and more particularly, machines for converting human-source mechanical power to electrical power.
- The exemplary embodiment of the present invention resembles a stationary bicycle (see, e.g.,
FIGS. 2C and 2D ) without a seat. The exemplary embodiment can be placed in front of a chair in which a person is sitting; the person can place their feet on the exemplary pedals of the exemplary embodiment, and pedal. The exemplary pedals are mounted on respective exemplary pedal arms, which are in turn mounted on opposing ends of a first axle. - The first axle of the exemplary embodiment extends through a center hole in a first geared sprocket wheel. The first geared sprocket wheel has a twelve-inch diameter. One complete revolution of the pedals translates into one complete revolution of the first geared sprocket wheel. In the exemplary embodiment, the pedals and pedal arms are mounted in such a way, and the pedal arms are of such a length, to provide ease of use and lower the torque needed to revolve the first geared sprocket wheel.
- When the person pedals, the mechanical motion of the person's pedaling is exerted on the first axle that extends through the first geared sprocket wheel. A sprocket chain connects the first geared sprocket wheel to a second geared sprocket wheel. The second geared sprocket wheel has a diameter that is smaller than the diameter of the first geared sprocket wheel. In the case of the exemplary embodiment, the second geared sprocket wheel has a diameter of seven inches. Because the second geared sprocket wheel's diameter is smaller than the first geared sprocket wheel's diameter, for every revolution of the first geared sprocket wheel, the second geared sprocket wheel makes more than one revolution. In the case of the exemplary embodiment, for every revolution of the first geared sprocket wheel, the second geared sprocket wheel revolves 1.71 times.
- The second geared sprocket wheel is mounted on a second axle. The second axle extends through a third gear wheel. The third gear wheel has a diameter of 11.5 inches. The third gear wheel is adapted to receive a first v-belt. The first v-belt connects the third gear wheel to a fourth gear wheel. The fourth gear wheel has a diameter of five inches and is adapted to receive a v-belt such as the first v-belt. The fourth gear wheel is mounted on a third axle. The third axle extends through a fifth wheel, which in the exemplary embodiment is a flywheel, with a diameter of 15.5 inches, and through a sixth gear wheel. The sixth gear wheel has a diameter of 11.5 inches and is adapted to receive a v-belt such as a second v-belt.

alternator pulley wheel 7. - If the human user were to pedal ninety (90) revolutions per minute, the above-described gear-to-gear ratio of the entire assembly (1:12.91) would result in 1125.9 revolutions per minute of the
alternator pulley wheel 7. - Therefore, with a moderate level of pedaling, averaging ninety (90) revolutions per minute or so, the 1100 RPMs necessary to achieve a 12.5 voltage output on the alternator would be achieved.
- The revolutions per minute of the human user (e.g., 90) are multiplied by the exemplary gear-to-
gear transmission assembly 100. The multiplication of power is accomplished by the exemplary ratios of the outer diameters of the various interconnected wheels, including the alternator pulley wheel. Specifically, in the exemplary embodiment, alarger wheel 1 with an outer diameter of twelve (12) inches is used to drive, via the gearedsprocket chain 12, asmaller wheel 2 with an outer diameter of only seven (7) inches. It is the outer diameter ratio of the two wheels (12/7) that results in the multiplication of one revolution ofwheel 1 resulting in 1.71 revolutions ofwheel 2. - In the exemplary embodiment,
wheel 2 with an outer diameter of only seven (7) inches, is connected viadrive axle 10 to a muchlarger wheel 3 with an outer diameter of 11.5 inches. By virtue of theaxle 10 connection ofsmaller wheel 2 tolarger wheel 3, each revolution ofwheel 1 results in 1.71 revolutions of not onlywheel 2, but also oflarger wheel 3. - In the exemplary embodiment,
larger wheel 3 is then connected with v-belt 13 tosmaller wheel 4 with an outer diameter of only five (5) inches. The outer diameter ratio ofwheel 3 as compared to wheel 4 (11.5/5) results in the multiplication of one revolution ofwheel 3 resulting in 2.3 revolutions ofwheel 4. Therefore, for each revolution ofwheel 1,wheel 4 revolves 3.93 times (1.71 times 2.3). - In the exemplary embodiment,
smaller wheel 4 is connected viadrive axle 11 to bothflywheel 5 andlarger wheel 6. By virtue of thedrive axle 11 connection ofsmaller wheel 4 tolarger wheel 6, for each revolution ofwheel 4,wheel 6 also revolves one time. In the exemplary embodiment,wheel 6 has an outer diameter of 11.5 inches.Wheel 6 is connected to alternatorpulley wheel 7 via v-belt 14.Alternator pulley wheel 7 has an outer diameter of only 3.5 inches. Therefore, for each complete revolution ofwheel 6,alternator pulley wheel 7 will revolve 3.285 times (11.5/3.5=3.285). Therefore, for each complete revolution ofwheel 1,alternator pulley wheel 7 will revolve 12.91 times (1.71 times 2.3 times 3.285=12.91). - It will be understood by someone with ordinary skill in the art that varying the outer diameters of the various interconnected wheels and the alternator pulley wheel could result in higher or lower RPMs as the case may be.
- For example, in an alternative embodiment,
fifth wheel flywheel 5 could be modified to itself accept an interconnecting means, such as a v-belt. In such an embodiment, a v-belt would interconnectfifth wheel flywheel 5 to alternatorpulley wheel 7. Such a modification would result in an overall turn ratio of 1:16.51 for the gear-to-gear transmission assembly 100. The 1:16.51 ratio would achieve 1320.80 RPMs for 80-pedal-revolutions ofwheel 1 per minute. - In a further alternative embodiment,
wheel 6 would be provided with a sixteen inch outer diameter; the flywheel would be removed from betweenwheel 6 andwheel 4 and would be mounted instead to alternatorpulley wheel 7. - Compactness of the
gear box transmission 100 is achieved in the exemplary embodiment by pairing large wheels with smaller wheels which are in turn connected via drive axles to larger wheels. As can be seen in, e.g.,FIG. 3 , the outer rim 1-1 ofwheel 1 is separated from the outer rim 2-1 ofwheel 2 by adistance 48. -
FIGS. 13A and 13B depict compact layering of the three gear stages. (stages one, two and three) of the exemplary embodiment.FIG. 13A is a right side plan view depicting exemplary layers of gears in the exemplary embodiment of the present invention.FIG. 13B is a left side plan view depicting exemplary layers of gears in the exemplary embodiment of the present invention. - Because the outer diameter of wheel 3 (in the exemplary embodiment, 11.5 inches) is smaller than the diameter of wheel 1 (in the exemplary embodiment, 12 inches), and because the outer rim 1-1 of
wheel 1 is separated from the outer rim 2-1 ofwheel 2 by a distance 48 (seeFIG. 3 ), side-by-side mounting ofwheel 3 on a common axle (10) withwheel 2 does not result in an interfering overlap with respect to the position ofwheel 1 or with mechanical-operating means attached to an axle (9) mounted inwheel 1. - Similarly, the assembly of
wheels single axle 11, and aligning the rim ofwheels belt 13 does not result in any interference as betweenwheels wheels - The exemplary device and its gear ratios balance high front-end torque with high-speed low torque at the back-end of the device. Alternative gear ratios could be used without departing from the spirit of the invention, but could result in alternative front-end torque or back-end speed. (Reference to the front-end of the device is meant to refer to the
wheel 1/handle 81 end of the device; reference to the back-end of the device is meant to refer to thealternator 8/battery 22 end of the device). - A yet further alternative exemplary embodiment (sometimes referred to herein as the “PMG embodiment” or as the “exemplary PMG embodiment”) of the present invention is described. In the exemplary PMG embodiment of the present invention, instead of a simple flywheel gearwheel (
element 5, e.g.,FIG. 1 ) and a separate, self-contained alternator (element 8, e.g.,FIG. 1 ) (such as an automotive alternator) as was employed in the exemplary embodiment, an exemplary permanent magnet generator (also sometimes referred to herein as a “PMG”)assembly 300 such as is depicted inFIGS. 21 and 22 , is used. In the exemplary PMG embodiment of the present invention, a portion of the permanentmagnet generator assembly 300 acts as one of the gear wheels. Further, the permanentmagnet generator assembly 300, when operated, generates electrical power in the form of alternating current (AC). Therefore, because it generates electrical power in the form of alternating current, the permanentmagnet generator assembly 300 is an “alternator”. Accordingly, as compared to a simple flywheel gearwheel (element 5, e.g.,FIG. 1 ) and a separate, self-contained alternator (element 8, e.g.,FIG. 1 ) (such as an automotive alternator) as was employed in the exemplary embodiment, in the exemplary PMG embodiment of the present invention, the alternator is integral to the gear wheel comprising, in part, the permanentmagnet generator assembly 300. - The permanent
magnet generator assembly 300 will generate low voltage, “three phase” AC. In the exemplary PMG embodiment of the present invention, as will be discussed further below, the alternating current generated by operating the permanentmagnet generator assembly 300 will be changed into “direct current” (DC) for charging a 12 volt battery (See, e.g.,element 243,FIG. 18 ). -
FIG. 18 is an exploded perspective view of further alternative exemplary gear box transmission components, including the exemplary permanentmagnet generator assembly 300, of the further alternative exemplary device for converting human power, or mechanical power, to electrical power in the exemplary PMG embodiment of the present invention. - Returning with reference to
FIGS. 21 and 22 , the exemplary permanent magnetgenerator assembly element 300 comprises astator 231 and two rotors (217 a and 217 b). (Reference herein to arotor 217 will be understood to apply to each of the two rotors 217 a and 217 b). - The
stator 231 of theexemplary PMG assembly 300 comprises a high-temperature epoxy into which is imbedded a plurality ofcoils 232 of wire; acenter hole 306 ofstator 231 is provided. In the exemplary permanentmagnet generator assembly 300, eightcoils 232 of wire are provided. In theexemplary PMG assembly 300, eachcoil 232 comprises two-hundred (200) winds of 16-gauge coated magnet wires. Eachcoil 232 forms substantially a circle with acenter point 303; eachcoil 232 measures approximately one-and-one-half inches in diameter. In theexemplary PMG assembly 300, thecoils 232 are imbedded in the stator equidistant from acenter point 301 of thestator 231 so that thecenter point 303 of eachcoil 232 is substantially the same distance fromcenter point 301 of thestator 231. The distance that thecenter point 303 of acoil 232 is positioned fromcenter point 301 will be referred to as “Radius A.” - In the
exemplary PMG assembly 300, eachcoil 232 is separated from acoil 232 on either side by a substantially standard distance, referred to herein as “Distance C.” In theexemplary PMG assembly 300, thecenter point 303 of afirst coil 232 is Distance C from thecenter point 303 of eachcoil 232 on either side of thefirst coil 232. - In the
exemplary PMG assembly 300, thestator 231 is encased around its perimeter in analuminum stator casing 237; the exemplary aluminum stator casing 237comprises aluminum that is approximately one-eighth of an inch thick, and is approximately one inch wide. - In the
exemplary PMG assembly 300, eachrotor 217 comprises a high-temperature epoxy into which is imbedded eightpermanent magnets 218. In theexemplary PMG assembly 300, eachrotor 217 comprises a disk of epoxy that measures approximately twelve inches in diameter having acenter 302. In theexemplary PMG assembly 300, acenter hole 308 is provided in eachrotor 217. - In the
exemplary PMG assembly 300, eachpermanent magnet 218 comprises a high-quality neodymium magnet measuring approximately one-half inch thick, and one-and-one-half inch in diameter with acenter 304. In theexemplary PMG assembly 300, thepermanent magnets 218 are imbedded in therespective rotor 217 at a substantially standard distance; the substantially standard distance is measured from thecenter 302 of therotor 217 to therespective center 304 of each of the respectivepermanent magnets 218. The substantially standard distance that thecenter point 304 of apermanent magnet 218 is positioned fromcenter 302 of therespective rotor 217 will be referred to as “Radius B.” - In the
exemplary PMG assembly 300, thepermanent magnets 218 are imbedded in therespective rotor 217, alternating face-up poles. For example, as depicted inFIG. 25A , magnets 218-1, 218-3, 218-5 and 218-7 would be imbedded in the epoxy rotor 217 a so that a north pole would be face up; magnets 218-2, 218-4, 218-6 and 218-8 would be imbedded in the epoxy rotor 217 a so that a south pole would be face up. In rotor 217 b, as depicted in, e.g.,FIG. 25B , magnets 218-1Q, 218-12, 218-14, and 218-16 would be imbedded in the epoxy rotor 217 b so that a south pole would be face up; magnets 218-11, 218-13, 218-15 and 218-17 would be imbedded in the epoxy rotor 217 b so that a north pole would be face up. - In the
exemplary PMG assembly 300, thecenter 304 of a firstpermanent magnet 218 is separated from thecenter 304 of apermanent magnet 218 on either side of the firstpermanent magnet 218 by a substantially standard distance, referred to herein as “Distance D.” In theexemplary PMG assembly 300, thecenter 304 of the firstpermanent magnet 218 is Distance D from thecenter 304 of eachpermanent magnet 218 on either side of the firstpermanent magnet 218. - In the
exemplary PMG assembly 300, Distance C is approximately equal to Distance D; Radius A is approximately equal to Radius B. Accordingly, in theexemplary PMG assembly 300, when rotor 217 a is placed (such as depicted, e.g., inFIGS. 18, 21 , and 22) so that themagnets 218 of rotor 217 a are facing themagnets 218 of rotor 217 b, and when themagnets 218 of rotor 217 a are aligned with themagnets 218 of rotor 217 b so that themagnets 218 of rotor 217 a are counter-posed to themagnets 218 of rotor 217 b, rotor 217 a is substantially a visual mirror image of rotor 217 b, and vice versa. - Even though when the
magnets 218 of rotor 217 a are counter-posed to themagnets 218 of rotor 217 b, rotor 217 a is substantially a visual mirror image of rotor 217 b, the magnets of rotor 217 a must be opposite in face-up pole from the correspondingcounter-posed magnets 218 of rotor 217 b. That is, a first magnet 218-1 (SeeFIG. 25A ) of rotor 217 a must attract a second, counter-posed magnet 218-10 (SeeFIG. 25B ) of rotor 217 b. - In the
exemplary PMG assembly 300, eachrotor 217 is mounted to arespective steel plate 216. In theexemplary PMG assembly 300, thesteel plate 216 is made of stainless steel. Stainless steel is used in the exemplary embodiment because it is not magnetic and because it does not spoil the effect of themagnets 218. - In the
exemplary PMG assembly 300, eachsteel plate 216 measures approximately one-quarter inch (¼″) in thickness and measures approximately twelve inches in diameter. In theexemplary PMG assembly 300, eachsteel plate 216 provides astop collar 307 that is welded in a center of therespective steel plate 216; eachsteel plate 216 provides fourholes 305 through which bolts can be threaded. In theexemplary PMG assembly 300, thestop collar 307 measures approximately three-quarters of an inch (¾″) in thickness. In theexemplary PMG assembly 300, fourfine thread bolts 215 are provided, each measuring approximately one-quarter inch (¼″) in diameter, and measuring approximately three inches (3″) long. - In the
exemplary PMG assembly 300, in order to maintain the mirror-image, counter-posed-attraction relationship as described above between themagnets 218 of rotor 217 a and themagnets 218 of rotor 217 b, eachrotor 217 is mounted to arespective steel plate 216 to form arotor 217/steel plate 216 assembly 309 (see, e.g.,FIGS. 18, 21 , 22, 25A and 25B). Fourbolts 215 are fitted through the fourrespective holes 305 of afirst rotor 217/steel plate 216 assembly 309 (see, e.g.,FIGS. 18, 21 , 22, 25A and 25B), e.g., theassembly 309 comprising rotor 217 b and arespective steel plate 216. The fourbolts 215 are slid through fourrespective spacing bars 236 that are extended through the inside of the perimeter ofhole 306 in thestator 231. The ends of the fourbolts 215 are then threaded through the fourholes 305 in the other rotor/plate assembly 309 (e.g., theassembly 309 comprising rotor 217 a and a respective steel plate 216). The threaded ends of each the fourbolts 215 are each secured with anut 250, such as in theexemplary PMG assembly 300, a one-quarter inch (¼″)nyloc nut 250. - With reference to
FIG. 18 , in theexemplary PMG assembly 300, ashaft 219 is inserted through thestop collar 307 andhole 308 in a first rotor/plate assembly 309, e.g., rotor 217 a/plate 216, through the center of thehole 306 in thestator 231, and through thehole 308 and stopcollar 307 of a second rotor/plate assembly 309, e.g., rotor 217 b/plate 216. Aset screw 224 is threaded through eachstop collar 307 to hold theshaft 219 in theexemplary PMG assembly 300. - With reference to
FIG. 18 , each end ofshaft 219 is rotatably anchored in opposing sides ofaluminum framework casing stop ring 206 on each end ofshaft 219. - Continuing with reference to
FIG. 18 , in theexemplary PMG assembly 300, thestator 231, encased in thealuminum stator casing 237, is bolted usingbolts 233 to bolt thecasing 237 to an aluminum framework casing floor panel 230 (See also,FIG. 20 ). Ends 232 a of thecoils 232 are attached to blockconnectors 240 which are in turn connected to bridgerectifiers 239. - With reference to
FIG. 20 , afirst pulley 225, such as a one-and-one-half inch (1½″) V-belt pulley 225, is attached to one exposed end ofshaft 219.First pulley 225 is set in place on the exposed end ofshaft 219 using aset screw 248. Much of the rest of the further alternative exemplary device is similar in operation to the exemplary embodiment and is described only in overview. - First V-
belt pulley 225 is connected with a first V-belt 228 to a second V-belt pulley 226. In the exemplary PMG embodiment, second V-belt pulley 226 measures approximately seven inches (7″) in diameter. Athird pulley 221 is connected to V-belt pulley 226 via anupper shaft 229. In the exemplary PMG embodiment, third V-belt pulley 221 measures approximately three inches (3″) in diameter. - Third V-
belt pulley 221 is connected via a second V-belt 227 to a fourth V-belt pulley wheel 220. In the exemplary PMG embodiment, fourth V-belt pulley 220 measures approximately 12 inches (12″) in diameter. In the exemplary PMG embodiment, fourth V-belt pulley 220 is attached to a mainpedal drive shaft 241. In the exemplary PMG embodiment, mainpedal drive shaft 241 is approximately three-quarters of an inch (¾″) in diameter and is milled to accommodate fourth V-belt pulley 220, aset screw 223, and apedal armature 350. - The further exemplary embodiment of the present invention may be operated by attaching foot pedals (or hand pedals) 18 to the
pedal armature 350.FIG. 37 is a perspective view of a foot/hand pedal operable device of the further exemplary embodiment of the present invention. - With reference to

As first V-belt pulley 225 rotates,PMG shaft 219 will rotate, causing rotation of the exemplary rotor/steel plate assemblies 309 (FIG. 18 ). - With reference to
FIG. 18 , as therotors 217 of the exemplary rotor/steel plate assemblies 309 are rotated, the counter-posed magnets become aligned (although in normal operation, only momentarily) with arespective coil 232 so that magnetic flux passes from a magnet, (e.g., North-pole faced-up magnets 218-1, 218-3, 218-5 and 218-7 respectively) on one rotor, e.g., 217 a, to the counter-posed magnet (e.g., South-pole faced-up magnets 218-10, 218-12, 218-14 and 218-16 respectively) on the other rotor, e.g., 217 b, through therespective coil 232; and from North-pole faced up magnets 218-11, 218-13, 218-15 and 218-17 on, e.g., rotor 217 b, to the counter-posed South-pole faced-up magnets 218-2, 218-4, 218-6 and 218-8 on, e.g., rotor 217 a. As the rotors continue to turn, the magnetic flux passing from one rotor, e.g., 217 a, to the other rotor, e.g., 217 b through aparticular coil 232, alternates so that the next pair of counter-posed magnets that are aligned with thatcoil 232 cause an alternate magnetic flux to pass through thecoil 232. The alternating magnetic flux moving through therespective coils 232 of thestator 231 produces electric power in the form of alternating current. -

In the PMG embodiment,battery 243 is a 12-volt mini lead-acid battery. As depicted inFIG. 38 ,battery 243 is a primary storage of the power generated by operating thePMG assembly 300.Battery 243 is connected to aground 31.Battery 243 is also connectable to a device operable with 12-volt power 38, such as a 12-voltautomotive device 39.Battery 243 is connected to a fuse 62-2, which is in turn connected,.via an on/off switch 67-2, to a first 110/120 AC/DC inverter 27 that can convert the 12-volt DC energy to 110/120 AC power for supplying power to a device that operates using 110/120 AC power, such as ahousehold device 32.Battery 243 is also connected, or connectable, to a battery isolator/regulator 333 for charging multiple batteries such as asecondary battery 330. Thesecondary battery 330 could also be connected, via an on/off switch 67-1, to a second 110/120 AC/DC inverter 27′ that can convert the 12-volt DC energy to 110/120 AC power for supplying power to a device that operates using 110/120 AC power, such as ahousehold device 32′. -
FIG. 39 is a schematic diagram depicting exemplary connections between theexemplary PMG assembly 300 and various electrical components of the exemplary PMG device in the exemplary PMG embodiment of the present invention. As depicted inFIG. 39 , ends 232 a of the coils (element 232 in, e.g.,FIG. 18 ) are attached to blockconnectors 240 which are in turn connected to bridgerectifiers 239. The alternating current generated by operating the permanentmagnet generator assembly 300 is changed via thebridge rectifiers 239 into ‘direct current’ (DC) for charging a 12-volt battery 243. Thebridge rectifiers 239 are connected to thebattery 243 via an on/offswitch 67, and a fuse 62-1. Avoltmeter 23 is provided to measure the charge tobattery 243.Battery 243 is connected to a first 110/120 AC inverter 27 (such as a 400 W inverter) to run devices that are operable via 110/120 AC power. Anisolator diverter 333 is connected, or connectable, tobattery 243 via fuse 62-2.Isolator diverter 333, when connected to chargedbattery 243, can be used to charge secondary batteries, e.g., 330, which can in turn be connected to a second 110/120AC inverter 27′ (such as a 400 W inverter) to run devices that are operable via 110/120 AC power. As depicted inFIG. 38 , aconverter 345 could be connected tobattery 243 to convertinput 110/120 AC current to 12-volt direct current to allow input to chargebattery 243. - As compared to the exemplary embodiment which required that the alternator pulley wheel must rotate about 1100 times per minute in order to generate electricity, the exemplary PMG embodiment with the
exemplary PMG assembly 300 recognizes electricity generation with very low RPMs. Indeed, the exemplary PMG embodiment with theexemplary PMG assembly 300 recognizes electricity generation following early rotation of the rotors. - Other features of the invention are implicit in the above-provided description and/or are depicted and/or implicit in the accompanying Figures.
