FIELD OF INVENTION

The present invention relates to a more precise control of buoyancy, but not exclusively, for attachment to large structures being lower, lifted, positioned and transported on the ocean. The present invention relates to controlling the depth and motion of buoyant force underwater. The invention generally applies to offshore floating structures used in the exploration and production of offshore minerals, such as semi-submersible vessels, tension leg platform and spur type platforms, more particularly to offshore floating structures having vertically spaced buoyancy capsule enclosed within an open cross-braced jacket framework or truss support structure including large floating offshore windmills. This invention further relates more specifically in generating clean alternating electrical current with the aid of buoyant force in pools, lakes and ocean, with precise buoyant force control and gravity force to regulate accurate frequency required to generate Alternating Current electrical power continuously. The US 13/573009 application filed 13 August 2012 and continuation-in-part of my patent application US 13/659406 filed 24 October 2012 are combined contents therein are incorporated herein.

BACKGROUND OF THE INVENTION

Firstly there are many way of lifting and transporting heavy structures in the ocean with certain amount buoyancy control, of these are pressurized air or gas inflated balloons and barges but non with a more precise control and rapid response in slowing down the lifting as the structure comes to the surface or maintaining a level float on the ocean surface.

Secondly there are many way to generate electricity today, among these are nuclear power, coal power, and gas power. However none of them is clean or reusable energy, these non- reusable fossil fuel resources such as liquefied natural gas, coal nor oil which will inevitably run out. Furthermore the fossil fuels environmental impact is causing serious cultural, socioeconomic and climate crisis around the globe, not to mention the safety and costs of the nuclear power. Therefore, many domains that use fossil fuel are gradually adding reusable energy to curve the environmental impact such as solar energy and wind power. However, with limitations

l and restrictions such as topography, climate and geographical locations, causes inconsistencies in power generation, additionally wind power and solar power has high construction, upkeep and power transport (power lines) costs. The present invention can replace fossil fuel economy to sustainable renewable energy base economy and bring energy globally, furthermore this device operates 24/7 continuously.

Thus to overcome the abovementioned problems of prior art, the present invention has provided practicability after deliberate design, calculations evaluation and experience, developed and design to combine the related art.

BRIEF SUMMARY OF THE INVENTION

It is a primary object of the present invention mainly provides repeated buoyant force control and generating Alternating Electrical Current continuously maintaining required frequency by turning the generator at a constant rpm.

Numerous methods of lifting and lowering objects from the seabed have been developed throughout the history of ocean engineering and exploration. The methods more commonly used today include cranes and lift bags and an assortment of Remotely Operated Vehicles. Cranes are popular for deep water lifts, and are used to depths of 2000m, however there are problems. An underwater lifting operation is common task, e.g. the offshore oil and gas production and the off shore wind industry. The current difficulties faced of lifting heavy structures off the ocean floor is methods of adjustment of buoyancy by controlling the amount of air or gas in balloons and in its size, along with the safety of the diving team going in deep water for short period of time repeatedly to achieve the objective. Buoyancy can provide a large lifting force with little energy, but it requires a control system. In the present invention position control system is designed and implemented to keep the body with the load at a reference position or to control speed of ascent. In addition the said invention is designed in combination of buoyant force with ascent tuning control parameters repeatedly whereby to generate AC electrical power with aid of buoyant forces in a pool or a lake continuously.

First aspect of the present invention is buoyant force control mechanism which is comprised of a rigid chamber of a fix size that is circular, square, triangular, rectangular or polygonal shape, to the desired length with one end of this chamber is open and the top end is a closed dome or cone shape to reduce friction during ascent of the chamber during buoyant force. The said circular, buoyancy chamber have a sealed piston with a sealed plunger rod or shaft both fitted with "O" seal rings, the said plunger rod is piercing out through the top of the dome, a vinyl diaphragm can be fitted instead of the piston, the diaphragm installed in the chamber is attached to the inner perimeter at the open end of the chamber, the said diaphragm is attached to the plunger rod, the plunger rod is extended out through the top of dome or cone shape of the chamber to operate the sealed vinyl diaphragm. The piston type plunger buoyancy chamber as shown in Figl A to IF can be fixed as, plurality of bundle chambers that are attached in a row to a heavy structure to be lifted from the bottom of the sea or ocean floor, the said sealed rods or shafts and pistons are pushed to the bottom in each chamber, towards the open end of each said buoyancy chamber by the rod or shaft whereby displacing water in the chambers and creating a vacuum in the chambers, this vacuum is vented by installing a small vent pipe on the top of the dome or cone shape of each chamber which lead to the surface of the pool or lake except in deep ocean floor, the vacuum can be overcome by pressurized air or gas buoyancy chamber, thus creating buoyant force to lift the heavy structure. As the structure is pulled up by buoyant force to the surface, the said rod or shaft and piston or vinyl diaphragm in the chamber is drawn in gradually thus allowing water in the chambers thereby reducing the buoyancy force as the load comes to the surface whereby maintaining a steady lift. The process of pushing or pulling the plurality of said pistons by the shafts or rods in the chambers can be achieved in many ways (e.g. air pressure, hydraulics, mechanical screw, cables and leverage). In a pool or lake application air or hydraulic cylinder is attached to the shafts or rods of the said chambers. The hydraulic or air systems is operated from the surface and controlled by sensors and computers. As for the ocean floor application of pushing or pulling the plurality of the shaft or rods and pistons in the said bundled chamber modules along with additional linked bundled chamber modules aligned in a row. The pushing and pulling is achieved by cables attached from a electric or hydraulic winch to a shaft or rods on top dome or cone shape side of the first sets of chambers on the structure and interconnected each other up to the bottom of the last sets of chambers in that row, the said rods of the chambers is extended equally through the piston at the bottom of the last sets of chambers, the extended rods are attached in a similar manner to a second electric or hydraulic winch towards the bottom of the structure, thus both end of electric or hydraulic winches operate independently to locate the pistons to the appropriate location in the chambers to increase or to decrease buoyant force as needed to control the structure as the structure comes to the surface. Additionally vacuum created by the sealed pistons in the chambers, these unbalance forces in and outside the chamber can be defused as depth increases by a compressed air or gas. The said buoyant force control system can be operated from the ocean surface electrically with electric winches, or hydraulic controlled winches. A rigid circular buoyancy chamber or large diameter tube may be used to achieve the goal.

The majority of all shipwrecks are caused by the ship simply running aground on rock, iceberg, a coral reef, a sandbar or even another wreck. The hull is the main body of the ship below the main outside deck. The hull consists of an outside covering (or skin) and an inside framework to which the skin is secured. The skin and framework are usually made of steel and secured by welding. However, there may still be some areas where rivets are used. The steel skin may also be called shell plating. This buoyancy device can be implemented in ship's hull framework to prevent shipwreck, as the massive rock lodged into the side of the Costa Concordia, which caused the luxury cruise ship to capsize, Titanic ran into a massive iceberg all this can be prevented by simply adding this device to all ship's hull framework, cargo ships could carry more cargo with aid of this device. By installing 2.28 bars pre pressurized sealed buoyancy chambers fixed size to the ship's hull framework thus during the emergency no action is need if the ship's hull get punctured any where it cannot flood the entire ship's hull due to the lightly pressurized buoyancy chambers welded or clamped to halls frame as life west.

According to the second aspect of the present invention as shown in Fig 2A is for larger structures to be lifted off the ocean in depth of approximately 6 meters to 144 meter against pressures up to 14 bars. The design of the buoyancy device is a collapsible chamber, the collapsible chamber is a folding bellows skit whereby the structure of the collapsible bellow chamber skeleton frame is rigid to withstand pressures well above mentioned pressures yet it is collapsible with aid of hydraulic or air cylinders operated from above water surface. The collapsible accordion skirting bellow chamber follows the movement of the expansion to ensure protection through the complete cycle of the expending and collapsing operation and to maintain the displaced water space thereby required buoyant force. The buoyancy chambers of small size generator or a large Mw Generating capacity power plant of this device uses circular, square, triangular, rectangular or polygonal shape collapsible bellow chambers and can be inserted with a scissor expendable lift type of a mechanism to expend the collapsible bellow chambers from inside the collapsible skirting of the said bellow chamber, with aid of hydraulics, air and or cables. The said scissors expending skirt bellows follow the movement of the chamber to ensure protection and buoyancy through the complete cycle of the expending and collapsing operation.

In generating electricity with aid of gravity and buoyancy as illustrated in Fig 2C, the buoyancy and gravity plays a major role thereby buoyancy control is applied to one end of long rigid lever arm along with variable gravity load to the other end of the long lever arm for homes and smaller businesses. Buoyant force is lifting one end of the said arm at the same time gravity load is applied at the other end of the arm thus turning the gearbox shaft at midpoint of the long lever arm. These forces on both sides of the long lever arm plays a vital role simultaneously to achieve the desired rotation with the aid of a one way clutch mechanism to turn the gearbox shaft of enormous torque, this is accomplished by adding multiple arms of identical design on the said common gearbox shaft to overcome that enormous torque to maintain the desired rpm on the generator for AC frequency. These arms are controlled and regulated to maintain the desired rpm at the generator end, this is accomplished with an aid of a hydraulic system that is further controlled by microprocessors.

In generating electricity on a power plant scale with aid of buoyancy as illustrated in Fig 3 A and Fig 4A, the buoyant force plays a major role.

In generating Mw capacity electricity with the aid of buoyancy as in Fig 3 A where this system can be deployed at sea and ocean near populated areas. This method of the using multiple buoyant forces to act simultaneously on a common shaft to deliver the constant torque and speed can maintain the required frequency (rpm) at the generator end. The buoyant force of each and every buoyant chamber continuously, systematic reciprocates the long arms attached to the platform deck, along with causing the truck tires and brakes with outer steel ring around the said tires (Fig 3G, 3H) to act as a one way clutch to turn the shaft in one direction with enormous torque thereby turn the gearbox input gears. This entire process and operation of the present invention the buoyancy generator is controlled and regulated with aid of microprocessor and computers

This said process of turning the generator is similar to a wind turbine generator except in the present invention the long arms reciprocate with aid of the overrunning clutches on each arm accumulatively with enormous torque and consistencies to maintain frequency (rpm). Device can be conveniently deployed at populated areas, verses the windmill turbine generator the three long blades operate with inconsistent gust of the wind causing the blades to vibrate and damage the gearbox with huge costs, furthermore wind power can be deployed at certain sites only, therefore power lines along with inverters and transformer costs goes up not to mention the upkeep.

A mechanical buoyancy electrical power generating machine. The primary object of this design as illustrated in Fig 4A is to accommodate the buoyancy electrical power generation of a Kw size unit for a residential home, a large business or industry, schools and a high rise building, furthermore Mw size units can also be implemented on the ocean near populated areas. This electrical buoyancy power generator is mechanical with almost no external assistance to function, zero fossil fuel or any other energy form except buoyant force. The said buoyancy electrical generator exerts its rotational force with the aid of the present invention buoyant force chambers, as each of the said chambers expends in each row of buoyancy chambers as in Fig4A accumulatively all the expended chambers apply enormous buoyant force turning the main shaft leading to the gearbox. The displacement of water is taking place due to the assistance from the rail system on both sides of the buoyancy chamber that guides the said buoyancy chamber simultaneously to expend at the bottom of the conveyer type mechanism that continuously moves all of the buoyancy chambers in a synchronize manner around the loop of the sprocket chain conveyer track. The rail track that guides the buoyancy chambers expansion can guide the said chambers contraction motion the entire length of travel around sprocket chain as a conveyer belt mechanism. Each of the buoyancy chambers in this electrical power mechanism has a bellow skit whereby the skeleton frame of the collapsible is rigid to withstand the external pressures as well as the twist forces and is further equipped with a scissor jack mechanism with two roller bearing pin are exerting out through said buoyancy chamber at the top outer end to glide on the dual rails. The said buoyancy chamber further has a locking mechanism to lock the scissor jack mechanism and release as the chamber expands and collapses. As the buoyant force of the said expanded chamber reaches the top it's struck by a release stud that collapse a spring loaded buoyancy chamber and continue it journey continuously on the conveyer chain. In comparison to combustion engine that operate at high rpm and only one piston firing at any given time, this would be a buoyancy engine at low rpm engine with all the expanded buoyancy chamber applying enormous torque with buoyant force.

In generating electricity with aid of gravity and buoyancy as explained in above paragraph, the buoyancy plays a major role on larger unit. The present invention can be implemented globally to generate clean electricity on huge scale to large industries and homes and supply the grid, furthermore in rural villages with no access to electricity where one unit of a medium size can power all the surrounding villages and farmers for agriculture, furthermore globally we can start replacing the nuclear and the fossil fuel power plant with larger power generating units of the present invention, the buoyancy and gravitational forces to produce clean and safe electrical power continuously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Buoyancy can provide a large lifting force with little energy, but it requires a control system. In the present invention buoyancy position control system is designed and implemented to keep the body with the load at a reference position or to control speed of ascent of the load in a pool or ocean. In the said invention the designed combination of buoyant force with ascent control parameters operated repeatedly whereby to generate alternating electrical current with aid of buoyant forces in pool, lake and ocean continuously, furthermore in areas where temperature harbors below freezing antifreeze can be added to the pool to keep the buoyancy chambers to operate continuously despite freezing conditions. The present invention is a buoyancy control mechanism which comprised of rigid chamber, of a fix size or collapsible accordion vinyl skirt bellow capsule chamber, to the desired length, width or height, furthermore the said buoyancy capsule chamber may be made of stainless steel, aluminum, titanium, carbon fiber, vinyl reinforced material or other suitable materials with watertight integrity suitable for marine applications under high pressures.

Referring to Fig 1 A there shown, somewhat schematically, a vertical open cross-braced jacket frame column 1 with vertically spaced at the four corner of the said column a set of buoyancy modules bundled 3 and interconnected linked in series thus applying a uniform buoyant forces to the column structure 1 at the point of application. The buoyancy modules 3 may be made of stainless steel, aluminum, titanium, carbon fiber reinforced material or other suitable low density materials with watertight integrity suitable for marine applications. Each buoyancy module cylinder chamber shown as the bottom ends of these cylinders are open and the top end is a closed dome/cone shape to reduce friction during ascent as shown in Fig IF may be made of a single cylinder module or may be made of several cylindrical chamber modules as shown in Fig 1 C of smaller diameter secured together to form a large (BBUMC) buoyancy bundled unitized module cylinders. Each such BBUMC is linked as in Fig 1C to another identical BBUMC so as to operate in a uniform manner, there can be as many as required BBUMC on single row to lift and control the structure in that specific part of the structure. The manner in which the row of BBUMC operates to create buoyant force is by two sets of winch cable assembly 9 at both ends 7of the row of linked BBUMC meaning as in this case at the top and bottom, where the cables 8 are tensioned. The cables 8 are connected to a common module link 4 sliding the plunger rod 12 connected to the piston 13 thus in each BBUMC, each piston 13 in each and every individual BBUMC and link in a row, thus moves together uniformly to increase or decrease buoyancy by displacing a volume of water and creating a vacuum in each module 3 that is overcome by a compressed module of gas or air or vented modules at the top of the lake or ocean by mean of a flexible tube to overcome high pressures as depth increases, thus should the cable 8 be pulled from bottom by winch assembly 9 the pistons 13 in every connected BBUMC in a row associated on common link will be displacing the water from each cylinder in that row and the top cable 8 release by the inactive top winch 9 thus maintaining the tension on the cables. This method of application of row of linked BBUMC can be installed vertically as shown in Fig 1A. or horizontally as per required structure to be lifted off the ocean floor. In this case vertical set of linked BBUMC has a top and bottom cable 8 winches 9 operated independently at the four corners of the column. To descent the structure, the same operation is reversed by top winch 9 pulling the piston in the cylinders thus causing the water to enter the modules. Another method to lifting a heavy load of the deepest spot in the oceans at a depth of 11 ,000 meters, at pressure of around 1,100 bars is by attaching, several row of BBUMC made of an independent structure of a lower density than water to offset the weight of the buoyancy cambers that would be fastened to the heavy load at several locations and a single winch cable to the surface will pull all the piston rods in all the cylinders that are required to lift the heavy load. The beauty part of this lift is, that the single cable will only have to displace the water in all the cylinders up to the length of the cylinder size and locking the pistons and rods at the new pulled position, the load will be lifted by the buoyant force with BBUMC structure, since the load is lifted gradually, upon reaching the top there will not be a violent outburst of the load due to the calculated displaced water to lift the load.

Referring to Fig IB, 1C and ID top winch assembly anchored to the structure as in Fig 1 A explained earlier, is operated hydraulically or electric motor from the top surface of the water. The BBUMC Fig IB Anchor Straps to attach Cylinders 15 to Structure 1 to be lifted along with a winch 9 above the said bundle modules. Each module has a shafts 12 piercing out of the dome/cone of the cylinders chamber. The shaft 12 and the dome/cone on the cylinder have seals 14 fitted to prevent any water entering the cylinder. Larger heavier structures requires multiple unit of BBUMC to be linked in a row so that the end of shaft is continued with aid of module link 4 to next set of bundle unitized module shafts and controlled with the same winch 9 (as shown in Fig 1C). The top of first set of BBUMC is attached to a common sliding unit 4, causing the sealed piston 13 attached to each shaft/rod 12 in the BBUMC below to retract simultaneously thus allowing the water to enter the cylinders chambers from the bottom uniformly (shown in Fig IB) including the multiple units of BBUMC below in the row, as required causing the structure to decent in controlled manner. In similar manner (shown in Fig ID) when winch 9 at the bottom is active the piston 13 is controlled to displace the water in each set of BBUMC to create buoyant force in controlled manner.

Referring to Fig IE and IF in a rigid buoyancy capsule chamber of a fix size that are circular or square, triangular, rectangular, polygonal shape to the desired length, with the bottom ends of this capsule chamber is open and the top end is a closed dome or cone shape to reduce friction during ascent of the chamber during buoyancy. Each of these circular chambers will have a sealed piston 13 and a sealed plunger rod or shaft 12 fitted with "O" seal rings 14. Buoyant force in present invention with aid of a cylinder 10 is designed so that its cylinders can withstand as much external water pressure as possible. Stronger the cylinder 10 walls, the higher pressures it can withstand and deeper towards the ocean floor the load can be lifted in controlled manner. The top of the cylinder 10 is dome/cone shaped to reduce friction upon ascent of the structure if attached upright, should the cylinder 10 be placed horizontal on the said structure would have no adverse effect on friction. The piston 13 is fitted with "O" seal rings 14 including the

shaft/plunger 12 rod at dome area to prevent water from entering the cylinder 10 chamber, as the shaft/plunger rod 12 moves back and forth moving the sealed piston 13 in the cylinder 10 thus increasing or decreasing the buoyant force as desired. The bottom of the said cylinder 10 is open with a strainer cap 11 causing the water to freely displace from the bottom of the cylinder 10. The diameter of the cylinder 10 will vary as desired per design. Much longer cylinder 10 can be operated on the ocean floor attached to a large structure without the use of shaft/ rod 12 attached to the piston 13. Longer cylinders have a longer piston 13 so they may not kink while sliding without the shaft/rod 12 in the cylinder chamber, along with a sealed steel cable holding the piston in locked position while passing through the centre of the said longer piston 13, the steel cable is further clamped to the piston so as to move the sealed piston 13 in both direction in the said cylinder with the cable through the piston 13, the top dome/cone area will be sealed only allowing the cable passing without allowing water entering the cylinder is not shown. Additional cylinders 10 can be bundled and operated in similar manner with the aid of cable guides, operated with hydraulic or electric motor winch as described above.

The present patent can be implemented in ship's hull framework, furthermore cargo ships could carry more cargo with aid of this device, or by installing 2.28 bars pre pressurized sealed buoyancy chamber fixed size without any moving parts to the ship's hull framework of a calculated amount of displaced water thus during the emergency no action is need if the ship's hull get punctured try to dump excess load, it cannot flood the entire ship's hull and bring the ship down due to the lightly pressurized buoyancy chambers welded or clamped to frame and walls, as life west thus preventing excessive water entering the hull and overcome the ship.

A major advantage of the said invention is the buoyancy volume of the displaced water in the said chamber is close to precisely maintained to the specified volume thereby the entire journey of the payload from the sea floor to the surface, the speed of ascent of the payload is maintained, compared to the underwater air filled lifting bags, where despite their usefulness are not safe. Specifically, they have one major drawback; the acceleration can create enormous

unpredictability in the ascent of a payload as the lift bag reaches the extremely high vertical velocities upon reaching the surface.

Referring to Fig 2 A and 2B in the collapsible accordion folding skirt bellow 41 capsule chamber with vinyl, rubber or other suitable materials with watertight integrity suitable for marine applications. Buoyancy chamber 38 and the top rigid cap 42 are fixed to each other as an upside down open box form and the said expandable vinyl 41 collapsible capsule folding chamber is fixed to rigid lid as a large metal disc 43 suspended inside the said box depending on the shape of the buoyancy chamber that is sealed and shut thus creating a vacuum when expended and pressure when collapsed, this pressure or vacuum is overcome by a pressurized buoyancy chamber or is vented above the water surface with atmospheric pressure or compressed gas in an accumulator at the surface not shown, this method of venting applied to all the different structural designed buoyancy chamber explained in the present invention. The structure of a collapsible bellow chamber frame 38 is rigid metal to withstand pressures well above 4.45 bars, the vinyl collapsible folding chamber with aid of hydraulic, air cylinders or a ball screw shaft driven by air motor, gas motor or electric motor 45 operated from above water surface. Top end of the said buoyancy capsule chamber 42 has a column 10 piercing out the said buoyancy capsule chamber frame 38 that is reciprocating the long arm in Fig 2C (#7). The collapsible accordion skirt bellow folding chamber 41 follows the fold movement of the expansion to ensure protection through the rigid buoyancy chamber 38 as complete cycles of the expending and collapsing operation and to maintain the displaced water space thereby the required buoyant force. The vinyl collapsible bellow buoyancy chambers can be circular, square, triangular, rectangular and polygonal in shapes, furthermore the said buoyancy chamber can be operated with an air or hydraulic cylinder or ball screw 45 scissor jack (lift) 44 type mechanism with electric motor or air motor.

Referring to Fig 2 A, 2B, 2C, 2D, 2E and 2F details of mid size buoyancy electrical generator where buoyant force and moving of weights 30 thereby gravitational force, this reciprocating of long lever arm 7 at midpoint of the said arm shown in Fig 2F the up and down movement of the vertical column 10 during the upward force of the buoyancy chamber 38 at the vertical column 10 simultaneously downward force of the weights 30, thus positive force is exerted to the gearbox 5 whereby the smaller 4 generator of 20Kw and up. Once the long lever arm 7 reaches the bottom of the angle of operation on weight side, both hydraulic cylinders shafts 13 operate as a unit is retracted thus causing the gear rack 20 to retract on roller bearing rail 20 to turn the involute gear 19 whereby to turn large sprocket gears 23 as a unit to turn clockwise, causing the sprocket chain 24 riding on outer sprockets 23. The chain is fixed 18 to move the weights 30 on bearings 26 toward the center of the long lever arm 7. The slave cylinder 8 is driven by primary master hydraulic cylinder 12 as both hydraulic shafts 13 moves, thus the slave cylinder 8 supply hydraulic fluids to the buoyancy hydraulic cylinder not shown located in the buoyancy chamber 38 in appropriate directions. The movement of the gravity force, weights 30 on one end of the long lever arms and the buoyant force other end are controlled and regulated to maintain the desired rpm at the generator 4 end, this is accomplished with an aid of a hydraulic system and or compressed air that is further controlled by microprocessors. An overall view of the collapsible accordion skirt bellows buoyancy chamber 38 forces and variable gravity weight force simultaneously apply rotational force to generate AC electricity in the present device with the aid of a one way clutch mechanism Fig 2G or 2H. Additional units of the said long lever arm 7 assemblies is added to the gearbox 5 shaft as needed to overcome the enormous force to turn the gearbox whereby the generator. The buoyancy chambers can be operated with the aid of a pool. In the present invention smaller AC electrical generator, can equipped with two types of buoyancy capsule chambers, one is the rigid of a circular fixed size as in Fig 2E or a collapsible rectangular accordion folding skirt bellow capsule chamber as in Fig 2C with vinyl type buoyancy chamber 38. By adding identical long lever arms 7 of same specification to the gearbox shaft 5 as required to turn the gearbox shaft 6 to achieve a positive sinusoidal reciprocating motion of each arm causing the generator to maintain the frequency/rpm to produce AC electrical power continuously. This entire operation is controlled and regulated to maintain the desired rpm at the generator 4 end, this is accomplished with an aid of a hydraulic and or air system that is further controlled by microprocessors. In the present invention of a small electric generating device, the device would work just the same with or without the weight control mechanism except the buoyant force would be increased and reciprocating arms will not be operated from the middle of the arm but the end of the long arm directly to the overrunning clutch with no weight control mechanism, thus by increasing the buoyant force and achieving the similar results as the larger generators as explained in Fig 3 A with or without the concrete support structure.

Referring to Fig 2G one way clutch mechanism (overrunning clutch) to turn the large gearbox shaft 4 on the smaller generator unit as well as larger generator units. The elongated open cross truss-braced tubular arm 1 is fixed to the hydraulic calipers 2 and the rotors 3 are fixed to the gearbox shaft 4 thus as a positive reciprocating of the elongated open cross truss-braced tubular 1 arm the hydraulic calipers 2 are applied turning the rotors 3 thereby the gearbox shaft, upon release of the rotors 3 by the hydraulic calipers 2 the elongated open cross truss-braced tubular arm 1 is recovering for the next positive action, this process is repeated on the entire row of the elongated open cross truss-braced tubular arms in the present invention turning the gearbox shaft 4 continuously thereby the generator.

Referring to Fig 2H one way clutch mechanism (overrunning clutch) to turn the large gearbox shaft, the function of this design is similar as the described in Fig 2F, the major difference is the caliper 1 that is entirely mechanical operated with spring 7 loaded grooved cam jaws 2 that matches the pattern on the rotor 4 and the rotor 4 is partially in the oil bath tank 6 to lubricate the cam jaws 2 and the rotor 4 continuously. The rotor 4 is fixed to the gearbox shaft not shown as the rotor 4 turns on the gearbox shaft, upon a positive stoke the said mechanical calipers that are fixed to the elongated open cross truss-braced tubular arm thus causing the caliper jaws 2 to lock due to matching grove that lock in one direction and releases in the opposite direction as a ratchet action on the rotor 4, the jaws slide 2 on the rotor 4 on recovery phase of the

reciprocating action of the said arm. The continuous rotation of the rotor 4 partially in the oil bath 6 lubricates the cams 2 on the said calipers 1 extend the service life of the said ratchet action. The following are the reference number to each part in the set of drawing from Fig 2A to 2F

Referring to Fig 3 A, 3B, 3C, 3D and 3E the present invention of buoyancy control is deployed to be used on larger Mw AC power plant size generator sets, a concrete structural elongated deck platform 2 on the ocean surface anchored to the shallow ocean floor with extended support pillars 3. Two shafts 7 connected to a gearbox 5 are laid out with support structures on the said concrete deck 2 platform almost the entire length of the said deck. An (EOCTFIRMFTM) elongated open cross-braced jacket truss framework interconnected rigid massive formed of tubular member 9 arms are each connected to the said gearbox shafts 7 alongside each other. One end of the entire EOCTFIRMFTM 9 arms are each connected to the said long gearbox shafts 7 at 90 degrees (perpendicular) as a elbow, along with a massive overrunning clutch assembly 8 as described in Fig 3G and Fig 3H on the said gearbox shafts 7, furthermore the EOCTFIRMFTM arms are shown as four sided box-like configuration tubular arm 9, it should be understood that the said arms maybe triangular or have three or more sides. At certain sites or locations only one long gearbox shaft may be used on the concrete deck platform to connect perpendicular to the EOCTFIRMFTM arm 9 members on one side of a single shaft appropriately accommodated per design due to high sea current conditions not shown. The said EOCTFIRMFTM arms 9 as reciprocating long arms, having first and second end to each elongated tubular arm member, the first end is connected to any of a large one way clutch 8 assembly as explained in Fig 3G, 3H mechanism which is inserted in the long shaft 7 as to turn a positive rotation on the gearbox 5 shaft. The pair of said long gearbox shaft 7 parallelly located on the concrete platform whereby each shaft have its own sets of said EOCTFIRMFTM arm 9 attached back to back at the first end of EOCTFIRMFTM arm is connected to the two gearbox shafts 7 side by side thereby to drive the gearbox 5 accumulatively. The said second end of the each and every EOCTFIRMFTM is fixed to the large triangular, rectangular, square, polygonal or circular as in this case vinyl collapsible bellow folding buoyancy 10 chamber inserted with a scissors lift 12 type assisted expending mechanism, operated by a hydraulic cylinders 13 or ball screw mechanism with electric motor or air motor from the water surface. During the expansion and contraction of the collapsible accordion skirt folding vinyl collapsible bellow folding buoyancy 10 chamber inserted with a scissors lift (jack) 12 type assisted expending mechanism, vacuum or pressure is exerted in the said buoyancy chamber, this is overcome by venting or by an accumulator assisted gas from above the water surface, Furthermore air motors can be used to operate the scissor jack type of a mechanism in the buoyancy chamber, the same said air used for the air motor can be used to inflate or offset the external pressures to a certain extend in the buoyancy chamber. As for larger AC electrical generator the bellow buoyancy 10 chamber's force is the major player in applying force since the weight of EOCTFIRMFTM arm 9 has a substantial gravitational force to sink the said EOCTFIRMFTM arm towards the bottom. Upon the positive ascent by the buoyant force of each of the said EOCTFIRMFTM arm 9 on second end of said arm, as understood by referencing the diagram in Fig 3C whereby first end is attached to the long gearbox shaft on a concrete platform along with a massive one way clutches 8 as explained in Fig 3G AND Fig H to overcome the enormous torque by the gearbox 5 to turn the generator 4 at the desired rpm. The structural elongated platform 2 on the ocean surface can be designed with two sets of gearbox and generator, one at each end, not shown. Additional EOCTFIRMFTM arm 9 members can be added to the long gearbox shaft 7 as needed or for spare units when some arm units in the gearbox shaft becomes defective thus continue to achieve the desired rpm on the gearbox shaft to maintain the required frequency of the generator or on an upgrade. A positive reciprocating movement of the EOCTFIRMFTM arms on both sides of the two long gearbox shafts is rotating in opposite direction to each other thus the accumulative force of the two gearbox shafts 7 transfers to a common gearbox shaft that enter the gearbox 5 input side thus the large Mw capacity generator are maintaining the required rpm to the set frequency to produce AC electrical power generator whereby to the step up transformers to supply the grid. The said sinusoidal reciprocating at the second end of EOCTFIRMFTM arms 9 are guided with a structure mounted to the seafloor and or protected with a slotted silo oval shaped type open cross-braced jacket frames formed is not shown, around the said collapsible buoyancy chambers 10 along with roller guides to protect from the sea current, as the buoyancy chambers 10 continuously goes up and down along with the second end of the long rigid 9 arms thus preventing the current from exerting sideways force to the collapsible buoyancy chambers as they travel up and down. At sea where ocean current will have a significant impact on the performance of the EOCTFIRMFTM arms 9 as they reciprocates, for that reason a row of interconnected slotted oval shape silo type large structure of jacket member frame mounted to the sea floor to encase the circular collapsible accordion skirt bellow folding buoyancy capsule chamber as to allow the sea current force to be reduced that impacts and to protect and guide EOCTFIRMFTM arm along with a platform on the said row of interconnected slotted oval shape silo type large structure of jacket member frame to accommodate an accumulator and all necessary accessory for each said EOCTFIRMFTM arm is not shown.

To overcome the enormous torque force of the gearbox 5 thereby the generator 4 and the gravitational force (weight) of the EOCTFIRMFTM arm 9 is achieved by vinyl collapsible bellow folding chamber 10 inserted with a scissors lift type assisted expending mechanism 12, the size of these collapsible bellow folding rigid chamber 10 can be significantly increased or by inserting multiple additional collapsible bellow folding rigid chambers 10 with expendable scissors lift type mechanisms side by side on each of the EOCTFIRMFTM arm 9 and operate as a unit, furthermore major benefit of the said design in all of the functioning apparatus the buoyancy chamber is sealed from the ocean saltwater thus extending the service life of each said apparatus in each of the buoyancy chambers.

Referring to Fig 3D and 3E a buoyancy chamber of different shapes can be rectangular, square, triangular, polygonal and circular shapes of rigid chamber 10 with vinyl or rubber accordion collapsible bellow folding inner chamber 14 with aid of a hydraulic scissor jack (lift) mechanism 12, exerting pressure on the rigid disc 16 thereby displacing water and increase buoyancy, the collapsible inner chamber is a folding bellows. A scissors lift 12 type assisted expending mechanism is enclosed in the said collapsible buoyancy chamber 14 of vinyl or rubber skirt and bellows fold follows the movement on the chamber walls 10 to ensure and to overcome the external pressures on the said walls, that are protected thereby maintaining the specified buoyant force. The major advantage of this design is the collapsible bellow folding chamber 14 is protected when the scissor 12 jack (lift) type device is expended by the hydraulic cylinder 13 or a ball screw electric motor or air motor thus as the vinyl or rubber bellow fold collapse 14, the bottom disc 16 is sealed by a rubber seal 15 and protects the vinyl collapsible bellow fold thus maintaining the displaced volume of water, furthermore when the said scissor 12 lift contracts pulling the rigid disc 16 in the chamber thus the vinyl or rubber bellow unfolds allowing water to enter the chamber. This entire operation of the buoyancy chamber is controlled from the surface.

Referring to Fig 3F the large multiple rectangular, polygonal or square vinyl accordion collapsible bellow folding chambers for Mw generating devices. The collapsible chamber is a folding bellows skit 4 is constructed of a rigid folding skeleton structure of collapsible bellow chamber frame that is rigid to withstand high pressures, furthermore a scissor lift 5 expendable type of a mechanism is inserted into the folding capsule chamber is to assist in expending the collapsible bellow folding chambers from inside the said collapsible skirt bellow chamber. The elongated open cross truss-braced truss tubular arm 1 as a reciprocating long arm as in this case is fixed to the three individual bellow folding chambers 4 to the support 3, can be arranged in any position and fixed to the said elongated open cross truss-braced truss tubular arm 1 thus each of the buoyancy chambers 4 can be controlled to expend or contract to maintain the desired force. The elongated open cross truss-braced truss tubular arm 1 that would be required to overcome the both the weight of the said elongated truss tubular arm 1, and all the buoyancy chambers 4 on the elongated open cross truss-braced truss tubular arm 1 and the resistant force of the gearbox shaft and the generator to maintain the specified rpm on the generator. With the aid of hydraulics, cables or ball screw shaft driven by air motor or electric motor all controlled from above the water surface. In the present invention the collapsible bellow skit made of carbon fiber and or reinforced vinyl material that has watertight integrity suitable for marine applications under high pressures, rugged UV resistant fabric, high strength, and superior abrasion resistance low density and not affected by most petro-chemicals. The scissors assisted mechanism 5 and expending vinyl skirt and bellows fold follows the movement of the chamber to ensure protection through the complete cycle of the expending and collapsing operation. Each vinyl fold section of the collapsible bellow folding chambers is reinforced with a heavy gauge chain link fence type of a wire link embedded in between the two layers of fiber reinforced vinyl skin of the said fold section along with maintaining a sealed chamber with a embedded wire link and piano hinges- continuous hinges insert in each fold thus the chamber walls to withstand the increased pressures.

The above described invention of the Mw capacity AC electric generating units can be implemented in a manmade pool, a lake to or in open sea or ocean anywhere around the globe. Therefore it is understood that the total energy required running the hydraulic pumps, sensor, control valves, electric motors, computers and or compressors to assist the elongated open cross- braced jacket truss frames rigid massive formed of tubular arm members is only fractional versus the energy compared to that is generated by the Mw AC electrical generator, this is due to the fact that only two of the said long elongated open cross-braced jacket truss rigid massive actuator arms need to be serviced with energy per side with hydraulic fluid or gas at any given time, the rest of the elongated open cross-braced jacket truss arms are either going up due to buoyant forces to apply positive force to the gearbox shaft or going down to return with aid of gravity weight of the long massive actuator arms without the use of any energy, fifty percent of the long massive actuator arms in the entire electric generating plant is going down due to gravity (weight) and fifty percent is going up due to, buoyant forces thus applying force on one direction due to the overrunning clutch mechanism to the gearbox shaft thereby continuously applying positive rotating force to the gearbox shaft accumulatively. In the present invention the operation of generating Mw AC electric power is controlled and regulated to maintain the desired rpm at the generator end with computers is further accomplished with an aid of a hydraulic system that is controlled by microprocessors.

Referring to Fig 3G and 3H one way clutch assembly (overrunning clutch assembly) for larger Mw size generator units. In the present invention on the long gearbox shaft 6 is fixed to a brake shoes assembly and a truck tire rims, a set of truck tires are fixed to the rims thereby as the shaft rotates so does the truck tires. The truck tires road contact surface are encased with thick metal band 9 attached to the long rigid power arm 1. The brake shoes 3 and brake shoes backing plate is fixed to the elongated open cross-braced jacket truss framework interconnected rigid formed of tubular arm member. The brake drum 2 and the tires, along with tire rim 8, is fixed to the gearbox shaft thus upon the cam 7 applied by external air brake boosters or electric ball screw assembly the brakes are applied and the shaft 6 is locked to the drum 2 as the elongated open cross-braced jacket truss framework interconnected rigid formed of tubular arm member 1 turns the gearbox shaft 6 along with the thick metal band 9 is binding the tires 5 with the "Z" type metal strip 4 as it binds to the tire causing the rotation of the tires 5 and the gearbox shaft 6. Due to buoyant force the positive ascent of the elongated open cross-braced jacket truss framework interconnected rigid formed of tubular arm member the tires 5 is applied by "Z" type metal strip 4 and the brakes 3 are applied at same time causing the gearbox shaft to be turn, this action of binding the tire 5 to the thick metal band 9 and brakes 3 applied to the drum 2 causes the long rigid formed of tubular arm member 1 to overcome an enormous torque applied by the gearbox shaft 6 whereby the generator. With enormous amount of torque required, additional units of the said overrunning clutch assembly can be applied by adding additional units of the said one-way clutch assemblies on both sides of the elongated open cross-braced jacket truss framework interconnected rigid massive formed of tubular arm member as required illustrated in Fig 8 to turn the gearbox shaft 6 whereby generator to maintain the rpm as required.

Referring to Fig 4A, 4B and 4C mechanical buoyancy electrical generator produces electricity by continuously, as a machine repeatedly displaces water in each of the chambers systematically thereby buoyant forces is continuously turning the gearbox main shaft 1. In the present invention the device is constructed in a pool, lake or ocean on a concrete platform 6, the concrete structural deck platform with pillars has a gearbox 2 including a generator 4 end ,shaft 1 with top sprocket gears 8 for each row of buoyancy chambers are individually supported. Collapsible buoyancy chambers is attached to a single set of sprocket gears 8 on both sides of each every pair of sprocket gears 8 and chain 10 as a conveyer belt type of a mechanism. The number of buoyancy chambers attached is evenly divide on both sides of every pair of sprocket gear and chain set as shown in Fig 4A. Both sides of each every pair of sprocket gears 8 and chain 10 or a conveyer belt type of a mechanism that has a first side and a second side, the first side are the collapsed chambers. The buoyancy chambers are been expended as they first enter the bottom cycle by rail guides 3 the said chamber begins to expend and where the roller guide pins 13 on the rigid top of the buoyancy chamber 9 make contact guiding rail thereby expending the buoyancy chamber at the same time the locking mechanism 17 locks the scissor jack 14 mechanism expended chamber 9 thus as the upward force of the buoyancy chambers above said expending chamber is moving the sprocket chain, as conveyer belt mechanism turning the gearbox shaft Ion each set of sprocket gear chain 10. As the cycle continuous the top buoyancy chamber 9 on the first side makes contact with a releasing mechanism 12 on the buoyancy chamber at the top of the platform 15 releasing stud to collapse the spring loaded scissor jack 14 mechanism in the buoyancy chamber thereby continues on the second side where all of the buoyancy chambers 5 are collapsed whereby the cycle continues to enter the first side again. This repeated process of the buoyant force in each chamber thereby each and every pair of sprocket gears and chain as a conveyer belt mechanism, accumulatively all the expended buoyancy chambers have an enormous force to overcome the torque at the gearbox 2. thus continuously turning the gearbox shaft 1 whereby the gearbox 2, furthermore the rail guides 3 can be extended to cover the entire travel journey of each and every buoyancy chamber in a cycle of travel thereby no need for a locking mechanism 17 to guide the buoyancy chamber expended on the first side. The rail guide3 can have an additional changeable rail on the first side to prevent the expansion of the said buoyancy chambers thus stopping the said machine. This said design in Fig 4a can be implemented on high rise buildings and pools, ocean especially in running rivers as a hydro generator with no need for dam thus not affecting the ecosystem or flow of water.

Referring to Fig 4C a buoyancy chamber for the mechanical buoyancy energy generator of Fig 4A (#9) where the buoyancy chamber is enclosed with a collapsible folding vinyl or rubber bellows skit 18 is attached to a rigid folding skeleton 19 structure of collapsible bellow chamber frame, with top and bottom disc, where one disc is mounted on the chain 10 or conveyer type mechanism the other side controlled by the rail 3. The said each enclosed buoyancy chamber further contains up to four scissor jacks (lift) 14 mechanism and a locking lever 17 at all four sides as the chamber expends thus keep the chambers scissor jack 14 expended position until the buoyancy chamber reaches the release stud 15 at the top disengaging the locked lever 12 and collapses the chamber due preloaded spring not shown in the chamber 9. Each of the said buoyancy chambers one end outer disc is mounted on a skid 16 that is fixed at least two set of the sprocket gear 8 and chain 10, as a conveyer belt mechanism to support all the buoyancy chambers in that row. As one of the chambers expends, one chamber collapses thereby transfers air directly vise versa repeatedly and continuously. Fifty percent of the buoyancy chamber in the said mechanical electrical energy generating plant is going down due to gravity (weight) and fifty percent is going up due to buoyant forces, the combination of the forces on the gearbox shaft 1 continuously rotationally applying positive rotating forces to the gearbox shaft accumulatively. The said buoyancy chamber of different shapes can be rectangular, square, triangular, polygonal and circular shapes of chamber along with the scissor jack 14 mechanism. In the present invention the operation of AC electric power generator is controlled and regulated to maintain the desired rpm at the generator end with the aid of computers and dual sets of guide 3 tracks.
