DETAILED DESCRIPTION OF INVENTION

[0016] The invention will be further described in connection with the accompanying drawings, in which various facets and views of the invention are illustrated in order to assist in the understanding of the build, workings and methods used by the various embodiments of the invention.

[0017] There are many ways for this invention to be implementedthese drawings are the simplest and easiest to understand. For example, a square tank is used in these drawings so each side can be viewed with less confusion; however, the tank can be of any shape or size. On the other hand, the invention can function without a tank at all, but instead, it could be in an open body of water, such as a lake, sea or river, and hooked to a floating platform. It could have more bladders and more shafts. The pistons could be contained inside the tank instead of sticking outside the water. Furthermore, variants of additional embodiments are possible. This is why the preferred embodiment used in these drawings is one of the simplest and easiest to understand as well as implement while keeping the new and unique parts of this invention intact.

[0018] Now looking at FIG. 1A, the preferred embodiment is comprised of a large square water tank (1) with three bladders (2) at the bottom of the tank. (1) All three bladders are the samethey have no bottoms and each has a short pipe with a valve (3) coming out of the top corner of the bladder. (2) This valve is in line and attached to with very short piece of pipe (27) that is just sticking out of the liquid and through the top of the tank (1). This short piece of pipe is attached to a pipe (28) for gas to travel through (herein sometimes referred to a pipeline). Each bladder (2) has a sensor to regulate the air pressure; in the event a bladder (2) is low on gas, the aerator (4), which is hooked to a manifold (36) located at or near the bottom of the tank (1) that is hooked up of a pipeline that goes to three holes in the tank and each go through a bulk head. Each of these three holes is lined up with one of the three bladders. (2) Just outside of the tank by each of these holes on the pipeline is a valve (6) that controls when to open or close to refill a bladder. (2) On the inside of the tank there is a pipe (7) that comes out of the bulkhead allowing the aerator to refill the correct bladder (2) as well as being filled to the proper level with gas.

[0019] The system is controlled by a computer (8) to automate all actions. In the preferred embodiment, the computer controls the valves, actuators and sensors through a series of timers, opening and closing valves based on times of actions as described herein. In the preferred embodiment, the computer controlling may comprise a readily available irrigation timer controller. All valves, actuators, aerator, and sensors have wire leading to a central harness at both the top and bottom of the tank. (1) They then go to the front of the water tank to the power supply (9) and/or the computer (wiring not in drawings). Additionally, the electric generator (20, charge controller (21), battery bank (23), and inverter (24) can be viewed by blocks on the turbine (5) (sometimes referred to as the windmill or windmill head) side of the preferred embodiment.

[0020] Each bladder is permanently connected to a guide rod. (10) Each guide rod (10) has small holes on one side that allow it to fit in a gear. (16) The guide rod (10) is slidably connected to a housing. (11, 25) This housing is pivotably connected (13) to a steel tube (12) that may be welded in place across the top of the water tank just below the water line. (14) The guide rod (10) of each bladder assembly is gearably connected to a gear (16, 26) which is affixed to the axel shaft rod (17). The axel shaft rod (17) rests upon supports (sometimes referred to herein as pillow blocks). (18)

[0021] Now turning to FIG. 1B, a three-dimensional rendering of the preferred embodiment can be seen, now showing one of the bladder assemblies, including the guide rod (10), guide rod housing (11), and bladder (2) tilted in a diagonal direction as described above to facilitate the release of the gas contained in the bladder (2) into a valve (3) and the short pipe (27) connected to the pipeline. (28) This oblique bird's eye view of the preferred embodiment permits viewing a side of the embodiment on the opposite side of the gears (6) and axel shaft rod. (17). Specifically, the means for causing the orientation of the bladder assembly includes the pivot connection point (13), the steel tube (12) welded to steady the pivotable guide rod bladder assembly, as well as the actuator bladder system (15) that, by engaging and releasing the bladder assembly, is the means for the vertical and diagonal orientation of the guide rod bladder assembly. Finally, a locking actuator (19) to hold a guide rod (10) in place when a bladder (2) has reached the top of the tank (1) just under the waterline (14) can be seen.

[0022] FIG. 1C is another three-dimensional rendering of the preferred embodiment from an oblique bird's eye view but in a 90-degree rotation from FIG. 1B. Most of the same items can be seen in FIG. 1C as in FIG. 1B, but in this view it is easier to visualize the three bladders (2) of the preferred embodiment and their relationship to the entire bladder assembly. In this Figure, one bladder is near the bottom of the tank (1), one bladder is near the top portion of the tank, and the third bladder is in the diagonal position (as in FIG. 1B) to release the gas within the bladder, as described herein. Worthy of note in both FIGS. 1B and 1C, the gear (6) can be seen disengaged from the guide rod (10) in the diagonal position, thereby not inhibiting the movement of the axle shaft rod (17) and turbine (sometimes referred to herein as a windmill head). (5) This assists in the continuous unidirectional movement of the turbine (5) and thereby continuous force output.

[0023] Now referring to FIGS. 2 and 3, each bladder and guide rod assembly (sometimes referred herein as a bladder system, piston or guide rod assembly) acts as a piston. Each bladder system is comprised of a bladder (2) with a valve on the top, a slidable guide rod (10), a housing (11) that is pivotably-connected (13), and three linear actuators (15) (19) contained above the tank that are connected to the housing (11) that is pivotably connected. One actuator (sometimes herein referred to as the tilt actuator) (15) moves the bladder system to and away from the gearing (16) that is on a shaft (sometimes herein referred to as a generator shaft) (17) with pillow blocks (18) that may be connected to the top of the tank (1) or connected to a walk-way or similar structure (not in drawings). The other two actuators (19) are used as locks to hold the pistons in place; one of these actuators is used to hold the piston near the top portion of the tank (herein sometimes referred to as the upper tank bladder actuator) and the other of these two actuators is used to hold the piston near the bottom portion of the tank (herein sometimes referred to as the lower tank bladder actuator). Having at least three bladder systems that are staggered in their linear motion in such a manner that at any one time one bladder system is expelling gas into another bladder system while the third bladder system is rising. Now we will go through a complete bladder system cycle.

[0024] Now looking at FIGS. 4 and 5, and in order to start the electrical energy generation of the present intention preferred embodiment, the first step is turning on the computer. (8) When the computer is done doing a system check, it will display a start button. Press the start buttonan actuator (15) opens and pushes a bladder system into a gear (16) on a shaft. (17) This shaft (17) is hooked to an electric generator (20) that, in the preferred embodiment, is connected to a windmill head. The electric generator (20) is connected to a charge controller (21) that is connected to either the grid through a grid inverter (22), or a battery bank (23) and inverter (24) for onsite use. Simultaneously, another actuator (19) that is being used as a lock to hold the guide rod (10) in place is closed and releases the guide rod (10) that is connected to a bladder (2) which is full of gas at or near the bottom of the tank (1) that then starts moving upward which spins the gear (16) on the shaft. (17) When the bladder (2) reaches the top of the tank (1) just below the liquid line (14), an actuator (19) closes which moves the bladder system away from the gear. (16) This puts the bladder system at a slight tilt (see FIG. 4). Simultaneously, another actuator (19) opens and locks the piston in place. Just as this is done, a second actuator (25) opens and pushes a second bladder system into a second gear (26) on the same shaft which starts the same process on the next bladder system. Referring back to the first bladder which is just below the liquid line (14) and slightly tilted (in FIG. 4), at the top of the bladder (2) is a very short piece of pipe with a valve (3) that is just sticking out of the liquid. (27) This lines up with a pipeline (28) that travels to the bottom of the tank (see FIG. 2). This line has two valves, one at the top end of the line (29) that butts up against the valve (27) on the bladder (2) that is just sticking out of the liquid, and a second valve (30) at the opposing end of the line at or near the bottom of the tank (1) just before it goes through a bulkhead into the tank. A length of pipe inside the tank (31) lines up with the next bladder (2) to be filled with gas. Simultaneously, the valve (3) on the top of the bladder (2) and the top valve (29) and bottom valve (30) on the return line open which allows the liquid in the tank to fill up the bladder (2) and pushes all the gas through the return line (28), filling up the next bladder (2) at or near the bottom of the tank. (1) When the bladder (2) is full of liquid, the top valve (29) and bottom valve (30) on the return line (30) close simultaneously; this keeps the gas return line (28) under pressure which results in very little gas loss, leaving the valve (3) on the bladder (2) open. Then the locked actuator (19) unlocks and releases the bladder (2) which is now full of liquid. The bladder (2) returns to the bottom of the tank. (1) Then the bladder valve (3) closes, thereby preventing any gas fill for the next cycle from escaping, and the locking actuator (19) locks the bladder system in place making it ready to be refilled with gas from another bladder system after it stops just below the liquid line (14) at the top of the tank.

[0025] Now looking at FIG. 6, a sample motion of the bladders can be viewed. The bladders (2) in this figure are generally rectangular without a side near the bottom portion of the tank. (35) In FIG. 6, the movement is seen in stages to illustrate the cycle of the bladders in rising, sinking, and the amount of gas and water in each bladder in each of the six cycle stages shown in FIGS. 6A through 6F. FIG. 6A additionally shows a simplistic illustration of the pipeline (28) that travels from the top portion of the tank (34) to the bottom of the tank (35) to transfer gas between the different bladders (2) as part of the cycle of the present invention. A bladder full of gas is illustrated by four circles in the bladder, the circles representing gas. A bladder full of liquid, here as water, is illustrated by small waves near the side of the bladder closest to the top portion of the tank. (34) Bladders partially filled with gas and partially filled with water, either filling with gas near the bottom portion of the tank (35) or filling with water (and therefore releasing gas) near the top portion of the tank (34), have only two bubbles and water waves (representing partially filled with water and partially filled with gas).

[0026] Now looking at FIG. 6A, three bladders (2) are seen in the tank. (1) The left bladder (31) at the left, the middle bladder (32) in the middle, and the right bladder (33) at the right. The left bladder (31) position is just below the waterline (14) releasing gas. As the left bladder is releasing gas, it is partially filled with gas and partially filled with water, as seen with partial waves and only two bubbles. The middle bladder (32) is rising, now filled with gas, as seen by the arrow indicating the direction towards the top portion of the tank (34) as well as by the four circles (bubbles) in the middle bladder. (32) The right bladder (33) is near the bottom portion of the tank (35) filling with gas, as indicated by only two bubbles and partially filled with water. The reader is to understand that, in this FIG. 6A, the air being released from the left bladder (31) is filling the right bladder (33) with air. In this embodiment, the bladders are without bottom sides, which permits the left bladder (31) just under the waterline (14) to fill with water as the gas is replaced with water because the air rises through the water towards the top portion of the tank (Archimedes' Principal). (34)

[0027] Now looking at FIG. 6B, the left bladder (31) is sinking now that it is filled with water. The arrow indicates that the left bladder (31) is sinking towards the bottom portion of the tank. (35) The middle bladder (32), filled with gas, has risen to the waterline (14). The right bladder (33), now also filled with gas, is now rising towards the top portion of the tank. (34) The reader should note that at any given time there are only eight air bubbles in total in all three bladders, intended to show that the amount of air in the system is constant and important for consistent motion and therefore power to the shaft (17) (not shown), the gears (16) (not shown), axle shaft (sometimes referred to herein as the generator shaft) (17) (not shown), and turbine (5) (also not shown).

[0028] Now moving to FIG. 6C, the left bladder (31) has reached the bottom portion of the tank (35) and is being filled with gas from the movement of gas from the middle bladder (32), which is releasing gas near the water line. (14) The right bladder (33) has reached the top portion of the tank (34) and therefore the guide rod (10) has caused the gear (16) to spin, thereby again turning the shaft (17) and turbine (not shown). (5)

[0029] Now referring to FIG. 6D, the left bladder (31) has been filled with gas and is rising towards the top portion of the tank (34) as indicated by the arrow. The middle bladder (32), has completed releasing gas, which was channeled into the right bladder (31), is now sinking towards the bottom portion of the tank (35) as indicated by the arrow. The right bladder (33) is at the top portion of the tank (34) and is ready to begin releasing gas into the middle bladder (32) once it reaches the bottom portion of the tank. (35).

[0030] Now looking at FIG. 6E, the left bladder (31) has reached the top portion of the tank (34) and the middle bladder (32) has sunk to the bottom portion of the tank. (35) As shown by the partial fill of water and bubbles of the right bladder (33), the right bladder (33) is in the process of releasing air into the pipeline (28, not shown) to partially fill the middle bladder (32) with gas.

[0031] Finally, looking at FIG. 6F, the left bladder (31) is at the top portion of the tank (34) and is ready to begin releasing gas into the left bladder (33) once it reaches the bottom portion of the tank. (35) The left bladder (33) is sinking towards the bottom portion of the tank (35), as shown by the arrow, now that the right bladder (33) is filled with water. The middle bladder (32), now filled with air, is rising towards the top portion of the tank (34), as shown by the arrow.

[0032] The cycle now begins again, as we would again look to FIG. 6A to see the next step after FIG. 6F, where the left bladder (31) is releasing gas into the left bladder (33) while the middle bladder (32) is still rising towards the top portion of the tank (34), still filled with gas.

[0033] Now referring to FIGS. 7A and 7B, the movement of gas is illustrated by arrows showing the movement of gas from the top portion of the tank (34) towards the bottom portion of the tank (35) through the pipeline. (28, not shown) FIG. 7A shows the bladders (2), with the left bladder (31) releasing gas, the middle bladder (32) rising towards the top portion of the tank (34), and the right bladder (33) at the bottom portion of the tank (35), being filled with the gas that was in the left bladder (31). Similarly, FIG. 7B shows the pipeline (28) in a simple illustration to show the flow of gas, indicated by arrows for direction and bubbles for illustration of gas. The waterline (14) is shown by small waves.

[0034] As a review, the preferred embodiment of the invention is an electric power generator equipment that has preferably three floatable bladders (sometimes herein simply referred to as a bladder) members positioned planarly adjacent to one another inside of a water tank member. The water tank member has a bottom, and lower portion above the bottom, sides, top, and an upper portion below the top. The floatable bladders have a top and sides, but no bottom. Although the pictures show the floatable bladders, and even the tank, as squares and rectangles, these bladders and tank can be of any shape. In fact, in one embodiment, the invention can be installed in a river, lake or other open body of water where the tank is merely a frame. In the preferred embodiment, the majority of the water tank member is filled with liquid but airspace remains at the very top portion of the water tank member.

[0035] The top of each bladder has a short pipe that extends from the top of the bladder upwards and contains a valve and sensor connected to the short pipe. In the preferred embodiment, a guide rod is permanently connected to the top part of each bladder and extends upwards and through the top part of the water tank where it is can slide up and down in a piston motion as well as tilt back and forth. Each of these three guide rods are held in place by a housing that is positioned above, and not touching, the water tank as well as a guide rod tube that holds the guide rods in place at the top of the water tank, both above and below the top of the water tank. Both of these guide rod housings are designed to retain the guide rod so that the guide rod can slide up and down within the housings in a piston motion. Each guide rod therefore has a guide rod housing and a guide rod tube housing. Additionally, the guide rod and the two corresponding housings for the guide rod have a support member that the guide rod housings are connected to a support member (cumulatively sometimes herein called a guide rod assembly for short). This is clearly visible in the drawings. In order to harness the energy of the guide rod piston movement, the guide rod has holes in it (gear rack), that are exposed between the guide rod housing and the guide rod tube housing because the holes are on the other side of the gear rod than the support member. The holes correspond with the teeth of a gear. Each guide rod assembly can pivot back and forth so that the guide rod gear rack can mesh with the gear and disengage from the gear as it is pivoted; in other words, the guide rod assembly is pushed into the gear and then moved away from the gear by pivoting the guide rod assembly.

[0036] The guide rod assembly is tilted by an actuator, and with three guide rod assemblies in the preferred embodiment there are three tilt actuators. Each tilt actuator is connected to or near the top of the water tank member and positioned so that when the actuator, such as a solenoid, is activated and deactivated, it functions the tilt the guide rod assembly (through the support member). The guide rod gear rack is therefore moved, by tilt, either into a meshing position with the gear or away from, and thereby disengaged, from the gear. As the guide rod moves up, the gear and gear rack are engaged, and when the rod moves down, the gear and gear rack are disengaged by the tilt of the guide rod assembly as a result of the actuators. In another embodiment, the gear and gear rack holes are replaced with another gear assembly, such as a rack and pinion assembly.

[0037] As described above, the bladders filling and exhausting gas, rising and sinking in the tank, are controlled in an alternating fashion, in part by upper tank bladder actuators and lower tank bladder actuators. Specifically, when a bladder reaches the top of the tank, an upper tank bladder actuator locks the guide rod in place and retains the bladder near the upper portion of the tank until the time is right for the bladder to fill with liquid and descend in the tank. Likewise, when a bladder reaches the bottom of the tank, a lower tank bladder actuator locks the guide rod in place and retains the bladder near the lower portion of the tank until the time is right for the bladder to fill with gas and ascend in the tank. Each floatable bladder has a sensor to monitor the gas pressure and volume. Both the upper tank bladder actuators and the lower tank bladder actuators are positioned above the tilt actuator and are connected to the corresponding support member of that guide rod assembly. A power source is connected to all of the different actuators.

[0038] The gas from the bladders moves from bladder to bladder through a manifold that has a bottom portion (near the bottom of the water tank), a side portion (near the side portion of the water tank) and a top portion (near that top portion of the water tank) and is attached to the water tank. The manifold bottom portion is attached to three bottom bulkhead valves that are attached to the water tank member bottom and each bottom bulkhead valve is positioned and aligned under a corresponding floatable bladder member. Each bottom bulkhead valve has a sensor and has a means that can open or close the valve at the correct time to fill a specified bladder with gas. In another embodiment, each bottom bulkhead valve has a pipe connected for directing gas to fill each floatable bladder corresponding to each bottom bulkhead valve.

[0039] Additionally, the manifold side member attached the bottom portion of the manifold to the top portion of the manifold, thereby spanning a water tank member side. The manifold top portion also has three top bulkhead valves that are attached at the top portion of the water tank member and have a sensor, power supply and means to control the opening and closing of the valve to allow the expulsion of gas from the bladder. The top bulkhead valve corresponds to the small pipe that extends from the top of a bladder and is engaged when the guide rod assembly, and therefore a bladder, is tilted into a position where the pipe and top bulkhead valve correspond. In another embodiment, each top bulkhead valve has a pipe connected for directing gas to escape each floatable bladder corresponding to each top bulkhead valve in order for the floatable bladder to fill with liquid and sink to the water tank member lower portion. Also, sometimes more gas or liquid may be needed the system, and an aerator valve sensor is attached to the manifold and attached to an aerator for inserting gas into the manifold and a liquid filling pipe is connected to the water tank member for infusing additional liquid as needed.

[0040] A wire harness assembly (containing connecting wires as well as a harness) is connected to each floatable bladder pipe valve sensor, each tilt actuators, each upper tank bladder actuators, each lower tank bladder actuators, each floatable bladder sensors, each bottom bulkhead valve sensors, each top bulkhead valve sensors, and each aerator valve sensor as well as a computer to automate all actions of the preferred embodiment of the invention as well as supply power to each of the valves and sensors and activators and aerator and liquid filling pipe control.

[0041] In order to harness the energy produced by the preferred embodiment, a generator shaft is connected to each gear such that as the gear turns, the generator shaft is turned as well. One end of the generator shaft is also connected to an electric generator for converting rotational mechanical power into electrical power. Specifically, the floatable bladders are staggered in their linear motion such that when one floatable bladder is expelling gas in the water tank member upper portion, another said floatable bladder is rising and another said floatable bladder is filling with gas in said water tank member lower portion, creating a continuous (or near continuous) turning of a gear and thus turning of the generator shaft. A windmill head and assembly may also be attached to the electric generator for additional electrical power. The electric generator can be connected to battery bank, electric circuit or circuit panel in order to use the generated electrical energy.

[0042] In alternative embodiments, the number of floatable bladders can more or less than three. In another embodiment, the manifold and bulkheads are all located inside of the water tank member.

[0043] Likewise, in another alternative embodiment, the guide rods, guide rod housings, guide rod housing supports, guide rod tube housings, tilt actuators, lower tank bladder actuators, upper tank bladder actuators, top bulkhead valves, and bottom bulkhead valves are all contained within the water tank member. In still another embodiment, and in addition to the foregoing, when the guide rod is contained completely with the water tank member, the gears cannot be connected to the generator shaft but must be connected to a different support structure. This involves the gears within the water tank member being connected to a flat belt, v belt, chain drive or cable to transmit the linear energy up through and above the water tank member and thereupon attached to a second set of gears attached to the generator shaft and another support member.

[0044] Although in the preferred embodiment, air and water are used, but the system is not limited to air and water, as other liquids can replace water and other gasses can replace air. For example, any inert gas can be used, such as a noble gas or nitrogen.

[0045] Upon reading this disclosure, those of skill in the art will appreciate still additional alternative structural and function designs for a using inflatable and deflatable air bladders (air boxes) with conservation of gas in a closed gas system in order to cause the buoyancy to drive an electric generator and turbine as well as using gravity to drive the liquid filled air bladders to the bottom of the tank and displacement to drive the gas into the next air bladder (air box). Thus, while particular embodiments and applications have been illustrated and described, it is to be understood that the disclosed embodiments are not limited to the precise construction and components disclosed herein. Additionally, variants of additional embodiments are possible. Therefore, the spirit and scope of the appended claims and the concepts taught herein should not be limited to the description of the preferred embodiments and embodiments contained herein.

[0046] For example, several different embodiments may include each part being a different size and/or shape and/or material; use of various types of generators; a multitude of return lines and air boxes in any size and/or shape and/or material; return lines and aerator manifold can be located anywhere inside or outside the tank; use of gases other than air and other liquids other than water; and, instead of a piston coming up out of the water in the tank, the piston can be hooked to the bottom of the tank and use a flat belt, v belt, chain drive, or cable to achieve the same results.
