[0026] FIG. 1 is an illustration of a simple block diagram of a system 100 that generate electricity when people walk on it, in accordance with the disclosed embodiments. The system

100 has a pathway 103, a moving bridge device 102 and a walk- through human detector 105. The moving bridge device 102 is installed just before the walk-through human detector 105. The system can be installed in public places, like a railway station. The moving bridge device

101 is connected to the pathway 103 on which people walks. At one end of the bridge 102 that is connected to pathway 103, people will walk from the pathway 103 towards the bridge 102. The other end of the bridge 102 is movable and is connected to the walk- through human detector 105. When the people walks from one end the bridge 102, the bridge 102 lowers at the other end near the walk-through human detector 105 and connects to the walk-through human detector 105 for the people to pass through. Please note that the walk-through human detector 105 and the other end of the bridge 102 will not be in the same level when no person standing or walking on it. When any one of the person walks on the bridge 102, the bridge 102 is lowered and is connected to the walk- through human detector 105.

[0027] The moving bridge device 102 has a moving bridge 102, a pulley system 104, a lifting system 106, a reciprocating to rotary converter 108, a flywheel 110 and a generator 112. The lowering pressure/force of the bridge 102 near the walk-through human detector 105 lifts a weight (not shown) in the lifting system 106 at the top of the system 100 through the pulley system 104. The pulley system 104 has one or more pulleys (not shown) installed on it to transfer the lowering pressure of the bridge 102 through a wire or rope (not shown) to the weight of the lifting system 106. When the people walks out of the bridge 102, due to no weight of the person on the bridge 102, the bridge 102 once again lifts up and the weight in the lifting system 106 is not sufficient to keep the weight lifted and hence the weight comes down. Thus, when each time the person walks in and steps out of the system 100, the weight in the lifting system 106 moves up and down once, thus creating a up and down reciprocating motion.

[0028] The reciprocating to rotary converter 108 converts the up and down reciprocating motion of the weight of the lifting system 106 to a rotary motion. The reciprocating to rotary converter 108 is connected to the flywheel 110, thus the rotary motion is transferred to the flywheel 110. The generator 112 connected to the flywheel 110 converts the rotary motion (mechanical energy) of the flywheel 110 to an electrical energy. In one embodiment of the invention the generator is a dynamo.

[0029] The system 100 further has a storage device 116 and/or at least one electrical equipment 114. The storage device 116 is used to store the electrical power generated by the generator 112. The generated power can also be used by at least one electrical equipment 114 in the places near, whether the system 100 is installed. For example, to illuminate the lights, to run fan, and so on, in the installed place. It should be noted that, one or more gears can be connected just before the flywheel 110 to increase the rotation speed of the flywheel 110.

[0030] In one embodiment of the invention, the moving bridge device 101 has the walk through human detector in it. In another embodiment of the invention, the moving bridge device 101 has pathway in it. In one another embodiment of the invention, the moving bridge device 101 has both walk-through human detector and pathway in it.

[0031 ] One another embodiment of the system 100 allows only one person to enter at a time, by restricting the other person to enter the bridge, unless the first person leaves.

[0032] The present invention is a renewable energy system that converts reciprocating motion of the platform into rotary motion. This machine can also be used in sea water to convert wave energy into mechanical energy and then convert mechanical energy into electrical energy.

In this embodiment, the generator is a dynamo.

[0039] It should be noted that the weight 105 of the lifting system 106 should be less than the weight of the person walking on the bridge 102, then only the weight 105 is lifted when the person walks on the bridge 102. In one embodiment of the invention, the weight 105 of the lift system 106 can be 18 Kg and the weight of the person walking on the bridge 102 can be more than 18 kg, for example more than 20kg. Depending on the weight of the person, the lowering of the bridge 102 happens at different timing. For example, when the person of lesser weight boards on the bridge 102, for example 20kg to 35kg, the bridge 102 lowers while nearing the human detector 120 or lowers just before completing the length of the bridge 102. When the person of heavy weight boards on the bridge 102, for example 61kg to 120kg (or more), the bridge 102 lowers as soon when the person boards the bridge 102. When the person of moderate weight boards on the bridge 102, for example 36kg to 60kg, the bridge 102 lowers when the person travels after passing say, for example, half to three forth of the bridge distance. Other weight variations for less, moderate and heavy weight are possible without limitation.

[0040] In one embodiment of the system 100, the bridge 102 can be of six feet and the height of the bridge 102 from ground level can be one and half feet. In another embodiment, the generator 112 is a wind dynamo. In another embodiment of the invention, the wind dynamo is of 10KW.

[0041 ] In one embodiment of the invention, the system 100 comprising the moving bridge 102 that can be installed on the ocean or sea, as a platform, to use weave energy instead of walking energy of human begins. A float can be installed on the bridge which can move and lower the bridge depending on the wave energy of sea/ocean.

[0042] FIG. 3 is an illustration of the system 300 of FIG. 2 with two stage arrangement of power generation, in accordance with the alternative embodiments. The system 300 has at least one moving bridge device 350, 351 for generating electricity, at least one pathway 103 connected to the moving bridge device 350 and at least one entry device 360 connected to the moving bridge device 351. The moving bridge device 350 or 351 comprises at least one hinged platform or moving bridge 301 or 302, at least one moving arm 306, at least one rack 314, at least one pinion 311, at least one gear wheel 308, at least one flywheel 312, at least one clutch 357, at least one counter weight 313, at least one power transmitter 305 and at least one generator 309. [0043] The hinged platform 301 comprises, a first end 304 and a second end 303, wherein the first end 304 is fixed and the second end 303 is free to move in a first direction 353 from first level A to second level B and in a second direction 354 from second level B to first level A, based on pull down force exerted on the hinged platform 301. The pull down force can be exerted on the hinged platform 301 when a human being or a person step into the hinged platform 301 from the pathway 103, while walking. When the human or person step into the hinged platform 301, the platform moves in first direction 353 from first level A to second level B and when the human being or person step out of the hinged platform 301, the platform 301 moves in second direction 354 from second level B to first level A. It should be noted that the first level A is higher than the second level B . The first direction 353 can be downward direction and second direction 354 can be upward direction. The hinged platform 301 of the moving bridge device 350 is fixed at first end 304 of the moving bridge device 350 at first level A to the body of the system base (connected to the pathway) using at least at least one hinge 355 and axel 356, as shown in the FIG. 3. Similarly the hinged platform 302 of the moving bridge device 351 can be fixed at first end 304 of the moving bridge device 351 at second level B to the body of the system base using at least at least one hinge and axel (shown but not numbered).

[0044] The reference numerals of various elements of the moving bridge device 350 in

FIG. 3 are numbered to explain the power generation using the moving bridge device 350. More moving bridge devices can be added/cascaded to generate more electrical energy. The moving bridge device 351 has the moving platform 302 which is installed in the entry device 360 comprising the human detector 361. The working of moving bridge device 351 is similar to the moving bridge device 350. In moving bridge device 351, when the human or person step into the hinged platform 302, the platform moves in first direction 353 from first level B to second level C and when the human or person step out of the hinged platform 302, the platform 302 moves in second direction 354 from second level C to first level B.

[0045] It should be noted that the various elements of the moving bridge device 351 are same and similar as in moving bridge device 350. Hence, only few elements of moving bridge device 351 are indicated in FIG. 3 using reference numeral.

[0046] The one end of the moving arm 306 is connected to the second end 303 of the hinged platform 301 using at least one power transmitter 305. The power transmitter 305 runs along the moving arm 306, rack 314 and the pinion 311. The Power transmitter 305 can be selected from at least one of a steel rope, a spring, a rope or a transmitting rod. The rack 314 has at least one linear teeth (not shown), wherein the linear teeth is connected to the other end of the moving arm 306. The moving arm 306 movement is smoothened by using at least one sliding channel 358. The sliding channel 358 can be a rail, channel or the like, to guide and smoothen the moving arm 306, when the moving arm is moved up or down. The rack 314 with linear arm moves as soon when the moving arm 306 moves in the first direction 353 or in the second direction 354 depending on, when the human or person step into or set out of the hinged platform 301. The pinion 311 is connected to the rack 314 by engaging the linear teeth of the rack 314 with at least one teeth of the pinion 311. The pinion 311 converts the linear movement of the rack 314 to the rotary motion. The gear wheel 308 can be used to transmit the rotary motion of the pinion 311 to at least one flywheel 312 using the shaft 310. The clutch 357 can be used to control the direction of rotation of shaft 310 in one direction. The counter weight 313 hang at an end of the power transmitter 305 can be used to bring back the moving platform 301 from second level B to first level A, when the human or person step out of the hinged platform 301. This moves the platform in second direction 354 from second level B to first level A. The counter weight 313 and the rack 314 are connected with power transmitter 305 using at least one pulley 365. The generator 309 can be used to convert the rotary motion of the shaft to electrical energy.

[0047] It should be noted that the hinged platform or moving bridge 301 of moving bridge device 350 is positioned at an elevated level, for example first level A. The hinged platform or moving bridge 302 of moving bridge device 350, 351 is positioned at an elevated level, for example second level B. The pathway 103 is connected to the first end 304 of the moving bridge device 350 and the entry device 360 is connected to the second end 303 of moving bridge device 351. The second end 303 of the moving bridge device 350 connects to the first end 304 of the moving bridge device 351, when at least one human being walk from the pathway 103 towards second end 303 of the moving bridge device 350. The second end 303 of the moving bridge device 351 connects to the entry device 360, when the human being walk from the moving bridge device 350 towards the second end 303 of the moving bridge device 351 to create a passage from the moving bridge device 350 to the entry device 360. When no person walking on the moving bridge/bridges or when the moving bridge/bridges is/are not applied with downward force, the moving bridge 301 and moving bridge 302 will not be connected to each other. Similarly, the moving bridge 302 will be connected to the entry device only when the person walks on it or when the moving bridge 302 is applied with downward force.

[0048] In FIG. 3, two moving bridges are cascaded to create a path from the pathway

103 to the entry device 360. Any number of moving bridges can be cascaded based the requirement of the environment or place where the system is installed. Further, the pathway 103 can be at elevated position, for example top of slope. Many moving bridges can be cascaded to replace the stairs/steps used in the public places.

[0049] It should also be noted that, the system 100, 200 and 300 represent the single inventive concept of the invention. The system 100 in FIG. 1 shows the invention in simplified block diagram, system 200 in FIG. 2 shows one embodiment of single stage electrical power generation using the moving bridge device 102 and system 300 in FIG. 3 shows dual stage electrical power generation using the moving bridge device 301, 302.

[0050] The moving bridge 301 or 302 can be a rectangular or square platform. The moving bridge 301 or 302 can also take the shape that is suitable for a pathway or entry device without limitation.
