The description above and below and the drawings of the present document focus on one or more currently preferred embodiments of the present invention and also describe some exemplary optional features and/or alternative embodiments. The description and drawings are for the purpose of illustration and not limitation. Those of ordinary skill in the art would recognize variations, modifications, and alternatives. Such variations, modifications, and alternatives are also within the scope of the present invention. Section titles are terse and are for convenience only.

According to an embodiment of the power generator system, the system is used to propel a vehicle as illustrated in FIG. 1. As shown in FIG. 1, battery set 10, motor 20, and charger 30 together can be viewed as the system's energy source component. Motor 20 is plugged to battery set 10. Battery set 10 is connected to charger 30 for charging.

There are a set of transmission devices in this embodiment including a water pump 50, a set of water circulators 60A, 60B, 60C, a set of water pipes 70A, 70B, 70C, 70D, and a set of transmission belts 40, 40A, 40B, 40C. This set of transmission devices can be viewed as the power generator system's transmission component. Water is used as a media to transmit motion. Any other similar fluid may be used instead of water.

Motor 20 and pulley 45R of transmission belt 40 are mounted on the same shaft 5A in a fashion that when motor 20 rotates, pulley 45R follows to rotate and drives transmission belt 40 to move.

Pulley 45L and water pump 50 are mounted on the same shaft 5B in a fashion that when pulley 45L rotates, water pump 50 operates to pump water into water pipe 70A.

A water circulator is a closed box with an impeller inside and two holes on the surfaces of the box that are connected to water pipes. Water circulators 60A, 60B, and 60C have impellors 65A, 65B, and 65C inside, respectively.

Water pipe 70A connects water pump 50 and water circulator 60A as a discharge pipe of water pump 50; water pipe 70B connects water circulator 60A and 60B; water pipe 70C connects water circulator 60B and 60C; water pipe 70D connects water circulator 60C to water pump 50 as a suction pipe of water pump 50.

The connections among water pump 50, water circulator 60 A, 60B, 60C, and water pipe 70A, 70B, 70C, 70D are sealed so together they compose a confined system with a certain amount of water initially provided inside. However, FIG. 1 illustrates these component connections in a partially exploded view for clarity.

As shown in FIG. 1, in this embodiment, impellor 65 A in water circulator 60A and pulley 45 AR of transmission belt 40A are mounted on the same shaft 5C in a fashion that when impellor 65 A rotates, pulley 45 AR follows to rotate and drives transmission belt 40A to move.

In the same fashion, impellor 65B in water circulator 60B and pulley 45BR of transmission belt 40B are mounted on the same shaft 5D; impellor 65C in water circulator 60C and pulley 45CR of transmission belt 40C are mounted on the same shaft 5E.

FIG. 1 shows a set of wind turbines 80A, 80B, and 80C, each with a control box 90A, 90B, and 90C, respectively. The set of wind turbines together with their control boxes can be viewed as the power generator system's power generating component.

Wind turbine 80A and pulley 45AL of transmission belt 40A are mounted on the same shaft 5F in a fashion that when pulley 45 AL rotates, the rotary of wind turbine 80A follows to rotate.

In the same fashion, wind turbine 80B and pulley 45BL of transmission belt 40B are mounted on the same shaft 5G; wind turbine 80C and pulley 45CL of transmission belt 40C are mounted on the same shaft 5H.

Wind turbine 80A connects to its control box 90A. Wind turbine 80B connects to its control box 90B. Wind turbine 80C connects to its control box 90C. Wind turbine control box 90C is connected to charger 30.

This embodiment illustrates the invention adapted for use in a motor vehicle. Vehicle motor 100 propels the motor vehicle. It is connected to wind turbine control box 90A. FIG. 1 uses a sketch of car light as a symbol to represent the vehicle's lighting system 110 and uses a sketch of an air-conditioning as a symbol to represent the vehicle's air-conditioning system 120. The motor vehicle's lighting system 110 and air- conditioning system 120 are connected to wind turbine control box 90B.

OPERATION

In accordance with the first embodiment of the invention shown in FIG. 1, to initialize a power generator system, one first initializes motor 20. Pump 50, water pipe 70A, 70B, 70C, 70D, and all three water circulator 60A, 60B, 60C are initiated with fluid/water at the onset, i.e. filled with fluid to allow for the pumping and circulating action. After motor 20 is initialized, one initializes vehicle motor 100.

When motor 20 is started, it drives pulley 45R to rotate. Transmission belt 40 moves following rotation of pulley 45 R. Pulley 45 L rotates following movement of transmission belt 40. Water pump 50 is driven to operate by rotation of pulley 45L.

When water pump 50 starts operating, water is pumped into water circulator 60A through water pipe 70A. Following water current impellor 65 A inside water circulator 60A rotates. Rotation of impellor 65A drives pulley 45AR of transmission belt 40A to rotate. Transmission belt 40A moves following rotation of pulley 45AR. Pulley 45 AL rotates following movement of transmission belt 40A. When pulley 45AL rotates, it drives the rotary of wind turbine 80A, which is mounted on the same shaft 5F, to rotate. Electricity is generated when rotary of wind turbine 80A rotates. The voltage and current of electricity generated from wind turbine 80A are adjusted through wind turbine control box 90A to be supplied to vehicle motor 100.

As the water current goes down from water circulator 60A to circulator 60B through water pipe 70B, the water current drives the impellor 65B inside water circulator 60B to rotate. Rotation of impellor 65B drives pulley 45BR of transmission belt 40B to rotate. Transmission belt 40B moves following rotation of pulley 45BR. Pulley 45BL rotates following movement of transmission belt 40B. When pulley 45BL rotates, it drives the rotary of wind turbine 80B, which is mounted on the same shaft 5G, to rotate. Electricity is generated when rotary of wind turbine 80B rotates. The voltage and current of electricity generated from wind turbine 80B are adjusted through wind turbine control box 90B to be supplied to the vehicle's lighting system 110 and air conditioning system 120.

As the water current goes down from water circulator 60B to water circulator 60C through water pipe 70C, the water drives impellor 65C inside water circulator 60C to rotate. Rotation of impellor 65C drives pulley 45CR of transmission belt 40C to rotate.

Transmission belt 40C moves following rotation of pulley 45CR. Pulley 45CL rotates following movement of transmission belt 40C. When pulley 45CL rotates, it drives the rotary of wind turbine 80C, which is mounted on the same shaft 5H, to rotate. Electricity is generated when rotary of wind turbine 80C rotates. The voltage and current of electricity generated from wind turbine 80C are adjusted through wind turbine control box 90C to be supplied to charger 30. Charger 30 charges battery set 10 using electricity generated from wind turbine 80C.

Wind is not required as the only energy source in this embodiment of the invention. It is possible that wind turbines 80A, 80B, and 80C are operated by any or combination of motor 20 and wind.

In accordance with the first embodiment of the invention shown in FIG. 1, to stop a running power generator system, one first shuts down vehicle motor 100, then one shuts down motor 20. The capacity of the entire power generator system can be adjusted by changing size and capacity of the motor 20, water pump 50, and wind turbines 80A, 80B and 80C. Size, shape, and capacity of transmission belts 40, 40A, 40B, 40C, pulley 45L, 45R, 45AL, 45 AR, 45BL, 45BR, 45CL, 45CR, water pipe 70A, 70B, 70C, 70D should be adjusted accordingly for wind turbines 80 A, 80B, 80C to provide the best performance.

Accordingly, the described power generator system can be used in vehicles, airplanes, residential houses, factories, and in other broad areas. It is easy to build and operate, without specific requirements as to location, time, and natural conditions.

Although the description above contains many specificities, these should not be construed as limiting the scope of the embodiment but as merely providing illustrations of the presently described embodiment.

For example, the transmission component can be as simple as one transmission belt connecting energy source component and power generating component; the power generating component can use wind turbines as generators but are not limited to wind turbines only; the number of motors and generators can be any combination of numbers; the media used in the circulators can be other types of fluid including air.

FIGS. 2 to 4 - Alternative Embodiment

According to another embodiment of the present invention, there is a power generation system, power generator and method thereof as illustrated in FIG. 2. In this embodiment, there is a reservoir or pool 1 for holding a fluid. Pool 1 is empty at a beginning point.

Conduit 2P, such as a water pipe, is a combination of pipe segments 2 and 2A connected by check valves 41, together with ball valve 51A and faucet 35. Fluid can only flow unidirectionally, in this case flows up freely and is prevented from being able to flow down in conduit 2P. A device such as check valve 41, along the conduit 2P serves to prevent reverse flow, thereby facilitating unidirectional flow. In this embodiment, there are a plurality of conduits, for example, three conduits 2P aligned together as shown in FIG. 2. All three conduits 2P are installed vertically, with the bottom end of each conduit open to fluid pool 1.

FIG. 3 shows the combination of one conduit 2P. Starting from the bottom end of conduit 2P, there is a short pipe segment 2S, a check valve 41, a ball valve 51 A, and a pipe segment 2J connected vertically. On top of pipe segment 2J, there are three identical check valve 41 and three pipe segments 2 connected in an alternative fashion. Conduit 2V is a curved segment that connects the top most pipe segment 2 to fluid tank 75.

There is a level conduit 2A joining to pipe segment 2J perpendicularly. Conduit 2 A has a faucet 35 that controls the fluid flow. Conduit 2 A is connected to an outside fluid flow, for example a water resource such as running water. Fluid tank 75 is a container that holds fluid. Conduit 2P has its one end connected to the top surface of fluid tank 75.

Also, conduit 200 is connected to any other type of natural water resources from a higher place, such as a water fall. A ball valve 5 ID is installed on conduit 200 to control the flow of the water from natural resources.

Safety pipe 61 is connected to the top surface of tank 75 and it has a ball valve

5 IB installed on it. The lower end of safety pipe 61 is open to pool 1. The ball valve 5 IB is connected to the lower end of the pipe 61 to control the fluid flow to be on or off.

Fluid pump 85 has its suction pipe connected to valve 51C and its discharge end connects to pipe 2B. Pipe 2B has one end open toward water turbine or water wheel 105 such that when fluid runs out of pipe 2B, water wheel (or a water turbine) 105 starts to rotate.

In this embodiment, water wheel 105 is connected to generator 115 by a set of shafts, pulleys and belts which serves as a transmission device that transmits and accelerates rotating motion from water wheel 105 to generator 115. Water wheel 105 and pulley 130A share the same shaft 108. Pulley 130A and pulley 130C are connected by belt 140A. Pulley 130A has a bigger diameter than pulley 130C. Pulley 130C and pulley 130B share the same shaft 125. And pulley 130B is bigger than pulley 130C. Pulley 130B and pulley 130D are connected by belt 140B. Pulley 130B is bigger than pulley 130D. Pulley 130D and generator 115 share the same shaft 118.

FIG. 4 shows the details of how the lowest check valve 41, ball valve 51 A, conduit 2A, and faucet 35 are positioned. The predefined level of fluid in pool 1 should be around the middle of the lowest check valve 41 of conduit 2P. A ball valve 51 A is installed immediately above the lowest check valve 41. Conduit 2A, which is in connection to an outside fluid flow, is connected to conduit 2J at a location above ball valve 51A and below the second check valve 41 (i.e. the second check valve 41 being second when counting from the bottom of conduit 2P.)

OPERATION

Before the power generation system is initialized there is no fluid anywhere in the system. Faucet 35, ball valve 51 A on conduit 2P, ball valve 5 ID on conduit 200, ball valve 51B on safety pipe 61, and ball valve 51C under tank 75 are all set to be off before the system is initialized.

There are a number of scenarios where this embodiment of the power generation system can be operated. Preferably, two scenarios include with only natural fluid flow resources like water fall, or, with only running water. As the circumstances may warrant, the system may interchangeably operate between natural fluid flow and running water in a toggle fashion depending on the availability of the fluid energy source. Another working scenario would include a combination of a water fall together with running water.

In the first scenario, to turn on the system, turn on ball valve 51C and 5 ID and then turn on motor 95. Water from natural resources runs into funnel 25 and runs through tank 75 and fluid pump 85. When water comes out of conduit 2B, it drops on water wheel 105 and water wheel 105 starts to rotate.

The rotating motion of water wheel 105 propagates to generator 115 through shafts 108, pulley 130A, belt 140A, pulley 130C, shaft 125, pulley 130B, belt 140B, and pulley 130D. Generator 115 generates power.

In the second scenario, only running water is used as the energy source. Turning on the system comprises the following steps:

first, turn on ball valve 5 IB on safety pipe 61; then turn on faucet 35 on conduit 2A; after faucet 35 is turned on, outside water runs into conduit 2P, goes up through check valves 41 and pipe segments 2 and 2V, and finally runs into water tank 75 and starts to fill up water tank 75.

When tank 75 is filled, water starts to run out of safety pipe 61. When water reaches a predefined level in pool 1, first shut off faucet 35 and safety valve 5 IB and then turn on ball valve 51C; following that, initialize motor 95.

Once motor 95 is on, fluid pump 85 starts sucking water and bubbles out from tank 75 and sends water out from conduit 2B. When water comes out of conduit 2B, it drops onto water wheel 105 and water wheel 105 starts to rotate. The rotating motion of water wheel 105 propagates to generator 115 through shafts 108, pulley 130A, belt 140A, pulley 130C, shaft 125, pulley 130B, belt 140B, and pulley 130D. Generator 115 generates power. Water drops into pool 1 from water wheel 105 and then gets sucked into conduits 2P and goes up into water tank 75 and falls onto water wheel 105 continuously.

By placing fluid pump 85 to pump water from tank 75, no air bubbles enter up into tank 75. Therefore, a very concentrated and strong water stream emerges out of conduit 2B. Fluid pump 85 serves to provide a suctioning effect to the emerging fluid pulled from the tank 75, thereby resulting in a suction upward through conduit 2P from pool 1 when valve 51 A is in the open position.

Since this embodiment is an open system, when the system is operated under the second scenario only for a long period of time, water may be lost due to evaporation. The water level in fluid pool 1 should be maintained to reach at least the predefined level, for example, by turning on water faucet 35 for a short while. There are many conventional ways to do so for one skilled in the field. As long as some mechanism is provided to keep the water level in pool 1 at a predefined level, the system will function optimally.

Stopping the system and restoring the system to the initial status is the same under both scenarios and comprise the following:

Ensure that safety valve 51B, faucet 35, and ball valves 50A and 50D are all turned off. Next, let motor 95 run until pump 85 get all water out from tank 75 and conduit 2P and safety pipe 61. Then shut down motor 95. Once all the water is drained from pool 1, the system is back to its initial stage.

It is also possible to pause the system and resume it when needed. When pausing the system in the first scenario, shut down ball valve 5 ID, and then shut down motor 95. In the second scenario, shut down motor 95 only without touching any other valves. That way, all water will remain in the conduits 2P, 200, 61, and water tank 75. Due to the check valves 41 throughout conduit 2P, the fluid will remain in the conduit 2P and is prevented from flowing in an opposite direction. When resuming the system, just restart motor 95.

For conduit 2P, a reason the ball valve 51A is set above the lowest check valve 41 and below conduit 2 A is to facilitate fixing the lowest check valve 41 when something needs correction. If the lowest check valve 41 does not function well, when fluid mns into the system from conduit 2A, there may be the possibility that the fluid will not go up conduit 2P.

FIG. 5 - Alternative Embodiment

FIG. 5 shows an alternative embodiment of the power generation system, power generator and method thereof.

A significant difference between the embodiment of FIG. 2 and this embodiment of FIG. 5 is that this embodiment does not use a fluid tank, nor a water wheel and simultaneously drives a plurality of generators.

As shown in FIG. 5, in this embodiment, a reservoir or pool 1, conduit 2P, and safety pipe 61 are connected in the same way as in the embodiment of FIG. 2. In this embodiment, there is shown only one conduit 2P, whereas in the embodiment of FIG. 2 there are three conduits 2P.

In this embodiment of FIG. 5, there are a one or more water circulators, for example, three water circulators 105A, 105B, and 105C. A water circulator is a closed box with an impeller inside and two holes on two ends connected to a suction pipe and/or a discharge pipe, respectively. When water is pumped into the water circulator, it drives the impellor to rotate. When the impellor rotates, the axis of the impellor follows to rotate.

The higher end of conduit 2P is connected to one open hole of the top most water circulator 105 A. Funnel 25 and conduit 200 is a pipe that connects to an external water flow resource, such as a water fall. Water circulator 105A is connected to water circulator 105B by a conduit 2C. One end of conduit 2C connects to the hole on the lower surface of water circulator 105 A. Another end of conduit 2C connects to the hole on the top surface of water circulator 105B.

Water circulator 105B and 105C are connected the same way.

The lower end hole of water circulator 105C is connected to conduit 2D. Conduit 2D connects to a valve 51C. Valve 51C is connected to the suction pipe of fluid pump 85. The discharge pipe 2B of fluid pump 85 is open to pool 1. The main axis of fluid pump 85 is connected to the shaft of motor 95.

Box 127 is a transmission box that can speed up the rotation speed of the shaft of water circulator 105 A, 105B, and 105C. The axis of each of three water circulator 105A, 105B, and 105C. is connected as input to three transmission boxes 127, respectively. One or more generators 115 are connected to the output axis of transmission boxes 127, respectively.

OPERATION

In this alternative embodiment, initially, pool 1 is empty. There is no water in the system. Faucet 35, ball valve 51A on conduit 2P, ball valve 51D on conduit 200, ball valve 51B on safety pipe 61, and ball valve 51C under fluid tank 75 are all set to be off before the system is initialized.

There are a number of scenarios where this alternative embodiment of the power generation system can be operated. Preferably, two scenarios include with only natural fluid flow resources like water fall, or, with only running water. As the circumstances may warrant, the system may interchangeably operate between natural fluid flow and running water in a toggle fashion depending on the availability of the fluid energy source. Another working scenario would include a combination of a water fall together with running water.

In the first scenario, to turn on the system, turn on ball valve 51C and 5 ID and then turn on motor 95. Water from natural resources runs into funnel 25 and runs through water circulators 105A, 105B, 105C, and fluid pump 85. When water runs through water circulators 105 A, 105B, and 105C, the shaft of each water circulator starts to rotate.

The rotational motion is propagated into transmission boxes 127 and gets accelerated. The accelerated rotational motion is finally propagated to generators 115 to generate power. The transmission box is adjusted such that the accelerated rotation makes generators 115 to reach their best performance. Water runs out from conduit 2B and falls into pool 1.

In the second scenario, only running water is used as the energy source to keep the system operating. Turning on the system comprises: turning on ball valve 5 IB on safety pipe 61 ; then turning on faucet 35 on conduit 2A; after faucet 35 is turned on, outside water runs into conduit 2P, goes up through check valves 41 and pipe segments 2 and 2V, and finally runs into water circulators 105A, 105B, and 105C to start filling up the circulators.

When the fluid/water fills up conduit 2P and circulators 105A, 105B, and 105C, water starts to run out of safety pipe 61 into pool 1. When water reaches a predefined level in pool 1, shut off faucet 35 and safety valve 51B and then turn on ball valve 51C. Following that, initialize motor 95.

Once motor 95 is on, water is sucked from water circulators 105 A, 105B, and 105C, by fluid pump 85. When water runs through water circulators 105A, 105B, and 105C, the shaft of each water circulator starts to rotate. The rotational motion is propagated into transmission boxes 127 and gets accelerated. The accelerated rotation motion is finally propagated to generators 115 to generate power. The transmission box is adjusted such that the accelerated rotation allows generators 115 to reach their best performance.

Water runs out from conduit 2B and falls into pool 1. Then the water is again sucked into conduit 2P, through water circulators 105A, 105B, and 105C, continuously, keeping the system operating. Fluid pump 85 serves to provide a suctioning effect to the emerging fluid pulled through circulators 105 A, 105B, and 105C, thereby resulting in a suction upward through conduit 2P from pool 1 when valve 51A is in the open position.

In the first scenario, when pausing the system, shut down ball valve 5 ID and turn off motor 95 while keeping all other valves at the same status. Then the system can be resumed by turning ball valve 5 ID on and starting motor 95 at any time.

In the second scenario, simply turning off motor 95 and turning it back on will pause and resume the system, respectively. A device such as check valve 41, along the conduit 2P serves to prevent reverse flow, thereby facilitating unidirectional flow. Due to the check valves 41 throughout conduit 2P, the fluid will be held in the conduit 2P and is prevented from flowing in an opposite direction.

In both scenarios, when stopping the system and restoring it to the initial status, turn off ball valve 5 ID and keep motor 95 running until all water is drained from conduit 2B. Then turn off motor 95 and drain water from fluid pool 1. That way, the system returns back to its initial stage.

Accordingly, the described embodiments of the power generation system, power generator and method thereof do not cause pollution, are easy and straightforward to build and operate, and are cost efficient and simple to maintain. In addition, the embodiments of the system can be built in desert areas. Furthermore, this invention provides flexibility for power supply. One can either use it to sustain the power demand from a range of a home to a city.

Although the description above contains much specificity, these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of several embodiments. For example, water is easy to find and safe to use. However, other types of liquid or fluid can be used instead of water, such as oil or in other embodiments a combination with water.

Also, in the illustrated embodiment of FIG. 2, there are three conduits 2P going into the tank 75. It is envisioned that there could be more or less conduits 2P connected to tank 75. When building a conduit 2P, more pipe segments and more check valves can be used.

Moreover, in the above stated embodiment, the water wheel is connected to the generator simply by two sets of pulley and belts. It is envisioned that a sophisticated transmission system can be used to transmit the rotating motion from the water wheel to the generator, or even to more generators.

When receiving external water resources into the system, instead of using a pipe 200, there are many other ways or types of conduits to implement receiving the fluid. The shape and size of the fluid tank and funnel may widely vary. According to some of the embodiments of an efficient power generation system and power generator, there are a number of advantages provided including: no environmental pollution caused; the power generation system is cost efficient and easy to build as well as operate; once initialized, the system is continuously operable all day, independent of the weather; the system does not require a large space for operation; and the system is easily scalable. Throughout the description and drawings, example embodiments are given with reference to specific configurations. It will be appreciated by those of ordinary skill in the art that the present invention can be embodied in other specific forms. Those of ordinary skill in the art would be able to practice such other embodiments without undue experimentation. The scope of the present invention, for the purpose of the present patent document, is not limited merely to the specific example embodiments or alternatives of the foregoing description.
