Abstract

Our world will need breakthrough clean-energy technologies such as Hydro-tower power plant, also greater energy efficiency is essential. Energy resources and power plants can be put into two categories: renewable and nonrenewable, but Hydro-tower power plant could use both of energy resources. Ocean currents, upwelling, and sinking are generated from a combination of temperature, wind, salinity bathymetry, and rotation of the earth. Ocean circulations, thermal vents, etc. can be suitable locations and resources for deploying Hydro-tower power plant. Electricity could be generated by the energy extracting devices such as turbines from the motion of water towards the ocean surface that generated from a combination of ocean circulation energy and thermal energy in the interior of the Hydro-tower power plant. It might seem counter-intuitive, but a big advantage of Hydro-tower power plant is providing flexible technologies that help flexible electricity generation corresponding with changing electricity consumption.

Title of Invention : Hydro-Tower Power Plant

Technical Field

[0001 ] This invention relates generally to ocean power plants, and, more specifically to submerge semi-submersible power plants that can extract a combination of ocean renewable energy and thermal energy.

Background Art

[0002] E nergy is fundamental to modern life. It is critical to human progress and to improving living standards for billions of people across the globe. G rowth in global energy demand will be led by the increasing electrification of the global economy; a large percentage of the world s energy demand growth over the next quarter century will be tied to power generation to support our increasingly digital and plugged-in lives. G lobal view of energy demand and supply highlights the dual challenge of ensuring the world has access to affordable and reliable energy supplies while reducing emissions to address the risk of climate change.

[0003] E lectricity production generates the largest share of greenhouse gas emissions. A thermal power station is a power plant in which heat energy is converted to electric power. The efficiency of power production in a conventional thermal power station, considered salable energy produced as a percent of the heating value of the fuel consumed, is typically 33% to 48%. As with all heat engines, their efficiency is limited, and governed by the laws of thermodynamics. Waste heat energy, which remains due to the finite efficiency of the Carnot, Rankine, Diesel, etc. power cycle, is released directly to the atmosphere or river/lake water, or indirectly to the atmosphere by using a cooling tower with water used as a cooling medium.

S ummary of Invention

[0004] Modern energy is one of mankind s most complex endeavors, and its path is shaped by countless forces. E nergy and climate change are defining challenges of this century. These facts offer challenges alongside opportunities, and will alter the global energy landscape. In general, progress on energy and climate goals requires practical solutions that are reliable, affordable and cost-effective.

[0005] Meeting energy demand safely, reliably, and affordably while also minimizing risks and

environmental impacts, will require advanced technology and expanded investment. It will require innovation. As the pace of technology development continues to accelerate; new solutions are likely to emerge to contribute to meeting energy and environmental goals. Best policy options to achieve that goal will be market-based, predictable, transparent and globally applicable to promote innovation and technology breakthroughs to address climate change risks. [0006] It can be said hydro-tower power plant to some extent is response to these questions and problems. In accordance with one embodiment a hydro-tower power plant comprises a tower coupled to an energy extraction unit and also to a means for hold tower, said energy extraction unit configured to extract energy from the flow of water.

[0027] Following description and the accompanying drawings provide examples for the purposes of illustration. However, these embodiments should not be construed in a limiting sense as they are not intended to provide an exhaustive list of all possible implementations. In other instances, certain structures and devices are omitted or simplified in order to avoid obscuring the details of the various embodiments. Various other components may be included and called upon for providing for aspects of the teachings herein. For example, additional materials, combinations of materials and/or omission of materials may be used to provide for added embodiments that are within the scope of the teachings herein. In the present application a variety of variables are described, including but not limited to components and conditions. It is to be understood that any combination of any of these variables can define an embodiment of the disclosure. Other combinations of articles, components, conditions, and/or methods can also be specifically selected from among variables listed herein to define other embodiments, as would be apparent to those of ordinary skill in the art.

[0028] When introducing elements of the present disclosure or the embodiments) thereof, the articles ^'a,_ ^'an, _ and ^'the _ are intended to mean that there are one or more of the elements. S imilarly, the adjective ^'another, . when used to introduce an element, is intended to mean one or more elements. The terms ^'including and ^'having are intended to be inclusive such that there may be additional elements other than the listed elements.

[0029] As shown in F igs. 1 through 6, a hydro-tower includes a vertical tower 20 and it rests on supporting legs 26. One embodiment of the hydro-tower power plant is illustrated in F ig. 1. The hydro-tower power plant has a tower 20 consisting of a stiffened wall of material which can be durable and supportive for turbine generator. In one embodiment, the wall of tower is a metallic stiffened structure, such as steel, aluminum, etc. However, the wall of tower can consist of any other material such as concrete, plastic, composite, etc. and could have conic, pyramid, hypothetical, etc. shapes. In order to increase in efficiency, wall of tower could formed by each form an each section shape or wall geometry can be changed. External appendix may be added to eliminate ocean current force on tower, and internal appendix in tower to induce current and increase in efficiency (not shown).

[0030] Coatings may be used for decrease in corrosion and heat conduct through wall of tower. Fig.

1 also has nuclear reactor 28 disposed on tower 20. Nuclear reactor 28 heats the fluid flowing through tower 20 to increase the velocity of the fluid flow. Although nuclear reactor 28 is disposed near outlet 22, nuclear reactor 28 may be disposed anywhere within or out of tower 20.

[0031 ] The tower 20 has an inlet 30 and an outlet 22. At tower, the inlet 30 is positioned at a first elevation within a body of a fluid, and, the outlet 22 of the conduit is positioned, for example, at a second elevation that is higher than the first elevation. The reasoning for positioning the outlet at a higher elevation is that the pressure at the higher elevation is presumably lower than the pressure at the first elevation, which causes fluid to flow from the inlet 30 to the outlet 22.

However, the inlet 30 and outlet 22 may be positioned in any manner to take advantage of a pressure differential and/or a temperature differential that yields a flow of fluid from the inlet 30 to the outlet 22. Inlets and outlets of the hydro-tower power plant of said tower may be in every angle such as vertical, horizontal, or diagonal.

[0032] This invention can use pressure difference between the column of water, for instance,

between surface of the sea and deeper elevation, to turn a turbine generator to create energy by tower, pipes, or conduit through the sea mountain (not shown).

[0033] Fig. 1 shows an embodiment wherein inlet 30 of tower 20 has a larger cross-sectional area than the cross sectional area of outlet 22. E mbodiments may have inlets and outlets with the same cross-sectional area or may have a difference in cross sectional area. Despite the relative cross-sectional areas of the inlet and the outlet the inlets and outlets of the various embodiments may have any shape that allows fluid flow through the tower 20 to motivate turbine generator. S piral flanges or External appendix outside of hydro- tower to reduce vortex shedding and VIV in strong ocean current and inside of hydro-tower to induce vortex inside of tower to increase current parameters. E xternal appendix guide external current such that reduced the force of ocean current (not shown). Also, appendix is used on hydro- tower power plant to increase stability and decreased force on platform due to ocean current.

[0034] As shown in F ig. 2, coil 32 is fixed to the S upportive structures 34. Structure of heat

exchanger can be network of pipes, extruded sections, duct, etc. in every shapes and arrangements. An nuclear reactor 28 generates heat, as its main production, which heat is pumped in a working fluid through outlet pipe 46 of reactor to the inner coil 32 and returned through inlet pipe 44 of reactor after heating water in the interior duct space of tower 20. Nuclear reactor rests on supporting legs 42. The coil 32 within tower 20 is heated from heat source to heat water within tower 20 and cause an upward water flow.

[0035] As shown in F ig. 3, a heat exchanger in the Hydro-Tower power plant with closed thermal cycle includes a coil 32; supportive structures 34; and an outlet pipe 36. Inlet 40 and outlet 38 of heat exchanger conduct a hot working fluid to and from coil 32 to heat water thereby.

[0036] As shown in F ig. 4, a nuclear reactor 28 in the Hydro-Tower power plant includes an inlet 44; an outlet 46; legs 42; and flanges 48. Hydro-tower power plant can utilize in different depths because a closed cycle is independent from the air.

[0037] Convection is the transfer of heat from one place to another by the movement of fluids. When fluid motion is caused by buoyancy forces that result from the density variations due to variations of thermal temperature in the fluid. In the absence of an external source, when the fluid is in contact with a hot surface, its molecules separate and scatter, causing the fluid to be less dense. As a consequence, the fluid is displaced while the cooler fluid gets denser and the fluid sinks. Thus, the hotter volume transfers heat towards the cooler volume of that fluid.

[0038] Heated fluid, which may be water under pressure, flows through coil 32 as it is circulated from reactor 28. Other working fluids may be used. Coils 32 have a hot working fluid pumped through them from end pipe 36 which has the working fluid circulated through it to pick up nuclear reactor 28 heat. The coil 32 heat water within the interior duct space of tower 20 which rises to draw cold water into tower 20 through the lower passages or inlet 30 of tower 20. In the outlet 22 of tower 20, the resulting water flow drives turbine generator to provide power. T ower 20 should be enough high, to reach a useful range of efficiency and should be short enough that outlet positioned lower than free surface 100. T urbine propeller 74 is directly driven by vanes or blades 76 which are turned by moving water.

[0039] Nuclear energy do not lead to the growing global warming problem; but currently most of the nuclear power plants must operate below the temperatures and pressures that coal-fired plants do, in order to provide more conservative safety margins within the systems that remove heat from the nuclear fuel rods. This, in turn, limits their thermodynamic efficiency to 30 32%.

[0040] Nuclear and radioactive disasters such as F ukushima, Chernobyl, etc. is unavoidable in using traditional nuclear power plants and always must be ready to next tragedy or radioactive leak or explosion. But due to abundance and preservation of water with low temperature in Hydro-tower power plant probability and risk of explosion is very low. If explosion is happened, only will have financial damage because this power plant have high distance to shore and they are unmanned. S ince do not have need for personnel directly.

[0041 ] A turbine generator (or more) is disposed in the tower such that fluid moving through the tower 20 motivates the turbine generator. Although turbine generator is disposed near outlet 22, turbine generator may be disposed at any position within tower 20. S haft-less turbine. conventional turbine, or any other types of turbine is used as said energy extraction unit. As shown in F igs. 5A through 5D, a shaft-less turbine that rest inside of case 24 of turbine generator. Watertight walls 52 of case 24 of turbine generator seamlessly joined to wall of tower 20.

Although a turbine generator is used in this embodiment to generate energy or electricity, any device could be disposed in the fluid path to take advantage (e.g„ mechanically or electrically) of the moving fluid. Fig. 5B shows watertight external casing 56 of turbine generator that rest inside watertight walls 52 with stiffener 54 and bolts 59 that inlet 51 of turbine generator join to tower 20 by bolts and nuts 58. The propellers driven by moving water are preferably located in the outlet 22 where they can be of reasonable size and easily installed and maintained.

[0042] As shown in F ig. 5c, a shaft-less turbine generator includes a Main casing 64; long bolts and nuts 60; and S eparable casing 62. S haft-less turbine could have stationary guide vanes 50 to direct the working fluid at the appropriate angle towards the propeller. The distance between the downstream edges of the guide vanes 50 and the leading edges of the propeller will have a bearing on the size of fish that can safely pass through the turbine, and prevent from large fish, sharks, etc. to inter and injured by blades 76 of propellers. F ig. 5D shows a shaft-less turbine generator which includes a shaft-less propeller 74 supported by the ball bearing 72. S haft-less propeller 74 have blades 76 fixed therein so that water will rotate the propeller 74 and thereby the shroud 78. A stator 82 which in use is fixed to the main casing 64, and a rotor 80 which is constrained for rotation within the stator 82 thereby and generate power.

[0043] As shown in F igs. 6A through 6C, a turbine that rest inside of watertight walls 52. Watertight walls 52 seamlessly joined to wall of tower 20. Fig. 6A shows watertight duct 85 of turbine generator that rest inside of watertight walls 52 with stiffener 54 and bolt and nut 58. Watertight duct 85 around the blades contains and controls the working fluid.

[0044] As shown in F ig. 6B, a turbine generator includes a blades 86; hub 88; fixed casing of

generator 92; strut 90; power cable 66; and conduit 84. T urbine could have stationary guide vanes to direct the working fluid at the appropriate angle towards the propeller (not shown). F ig.

6C shows a sectional view of turbine generator which includes a generator 96; blades 86; and hub 88 that supported by struts 90. F ixed casing of generator 92 will joined to shaft 94 by tiltable pad 98. T urbine have blades 86 fixed therein so that water will rotate the hub 88 and thereby the shaft 94. A generator 96 which in use is mounted on the fixed casing of generator 92, and a shaft 94 which is constrained for rotation within the generator 96 thereby and generate power.

[0045] Abundance of supply and a broad range of energy choices have been enabled by

technological innovation. The gains largely will come from technology-enabled sources, such as tight oil, deep water and oil sands. These advances have stimulated a new "age of abundance" in energy supplies, which is good news for billions of people seeking to advance their standards of living. On the other hand a new "age of abundance" in energy supplies is bad news for billions of people seeking to a continued slowdown in the growth of global carbon dioxide emissions. [0046] A global movement towards the generation of renewable energy is well under way to help reduce global greenhouse gas emissions. Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight wind, rain, tides, waves, and geothermal heat. The biggest advantage of renewable energy is that they do not lead to the growing global warming problem. But it should be noted that renewable energy has big disadvantages. The former Big Disadvantage of Renewable E nergy is that there is a difficulty in generating large quantity of electricity. As compared to the conventional generators on fossil fuel, the quantity of electricity that is produced is large. This only means that there is a need to reduce the energy that will be used. Or else, there is a need to create many energy facilities. It may even indicate that the ultimate solution to the energy problems is the balance on many various power sources. The latter Big Disadvantage of Renewable E nergy is that

Renewable energy mainly relies in the weather, which is the ultimate source of power. In regard with hydro generators, they need rain in filling dams and supplying a continued flow of water.

Wind turbines also need wind in turning the blades. C lear sunshine and skies are needed for solar collectors. Once these resources are not found, the capacity in making energy is less. This may be inconsistent and unpredictable.

[0047] Hydro-tower power plant used both thermal energy and renewable energy. Indeed, the

integration of upward water movement and natural upwelling phenomenon such as natural cycle of ocean circulation in places where there is upwelling and water rising duo to decrease in salinity and heat on hot spring and fresh water and other phenomenon is possible in interior space of a tower. At the end of a hull such as conic hull where smaller crossing section with one or several turbine can harvest this energy. In the case we use of fossil fuel, by increasing and decreasing heat in furnace, power generation may be increased or decreased hourly.

[0048] Fig. 7 shows a tower 20 includes supporting legs 26 that it rest on seabed/base 104. Inlet 30 must be on hydrothermal vents or subsea fresh water springs 102. Convection is the transfer of heat from one place to another by the movement of fluids. When fluid motion is caused by buoyancy forces that result from the density variations due to variations of temperature and salinity in the fluid. Hydrothermal vents and fresh water springs 102 will cause the fluid to be less dense. As a consequence, the lighter fluid is moved upward. Where geothermal sources provide enough hot water, these may be directly passed through tower 20 without need to additional hot source.

[0049] Dissolved particle and other impurity of hot source can be filtered or heavy metals recycled with some machines. Hot vents 102 can be used in combination with other method in hydro-tower power plant. Also in other cases we can passed hot water through pipes and use heat of water, and discharge out of tower 20 because of high water density. In this case cost- benefit approach can help (not shown).

[0050] Fig. 8 is substantially the same as F ig. 1 except that water in duct of tower 20 is heated by the circulation of a lower temperature working fluid through coil 32 from conventional thermal power plant 106 to drive generator 96. Outlet 108 of thermal power plant 106 is, for example, at a temperature higher than that of the fluid flowing through duct of tower 20. Thus, the fluid flow cools coil 32 and is heated by coil 32, which increases the velocity of the fluid flow. Although pipe 110 is shown on sea bed between outlet 108 of thermal power plant 106 to outlet 109 of pipe 110 at bottom of tower 20.

[0051 ] Fig. 9 shows a tower 20 and barrage 114 includes transfer pipe 118. Density and buoyancy forces are changed with variation in salinity and temperature. In result water in duct can rise by decrease in its salinity and increase in its temperature. Fresh water from river have low salinity and in huge volume flows into the seas. When free surface of river 112 rise enough behind of barrage 114. Pipe 118 lay on river bed 122 and seabed 104. Lighter water transfer by pipe 118 and flow from inlet 116 of pipe 118 to outlet 120 of pipe 118 into inlet 30 of tower 20. A turbine at inlet 116 of pipe 118 can absorb energy that pipes used for pass lighter water (not shown).

[0052] In this case, density of river water or sewage or other water that can increase efficiency

because of reduction in density of inner water.

[0053] The vertical rise could be extended by placing a tower about the top of the main tower 20.

This large vertical rise will provide a very high current velocity through the towers with a resultant high power production. F ig. 10 shows a multi-stage hydro-tower power plant includes outer tower 128 and inner tower (first tower) 130. Legs of outer tower 124 and legs of inner tower 126 rest on seabed although outer tower 128 can rest on first tower 130. Conduct heat transfer from wall of inner tower 130 and heated water from inner tower 130 may be useful for outer tower 128.

[0054] In open thermal cycle, cold water can be heated and transferred to interior of power plant. F ig.

11 shows the floating hydro-tower power plant includes tower 20; anchor cables 136; and buoyancy tank 132. Nuclear reactor located in buoyancy tank (not shown). Renewable or non renewable energy in a current induction unit inside of said submersible tower, could induce a current of water into said submersible tower by heating water or any type of uprising method. In deep sea, in order to operate hydro-tower power plant in surface layer, short legs 134 of tower 20 can be tethered to anchor 138 by a set of tendon, chain, cable, catenary, etc. provided that power plants buoyancy is more than power plant s weight. Anchor 138 rests on the seabed 104. This buoyancy tank 132 can be seamless with power plant or with tendons joined to hydro-tower.

S ubmersible tower may be made from light material that said power plant can rise with or without adding buoyant tank and said anchor cables are stretched.

[0055] As shown in F ig. 11, the floating hydro-tower power plant includes a tower 20 that it is

positioned by a series of downwardly extending anchor cables 136. The submersible hydro-tower power plant is preferably positioned a desired distance down the water s surface to maintain the equipment out of the reach of waves, ocean spray and the like. Thus, each turbine is provided as shown with a plurality of cable 136, which are judiciously disposed in bottom of tower 20, short legs 134, etc. hydro-tower will support by the necessary buoyancy tank 132. [0056] At first buoyancy tanks 132 can be flooded or ballasted by opening the flood valves which are attached to each tank. The submersible tower is free to guidably descend to the ocean floor. E ach support cable 136, is provided with a hold down cable assembly which extends from the cable winching equipment, downward to anchor 138. Basically, each anchor cable 136 is connected to an anchor 138 in such manner that when tension is applied to the cables through cable winching mechanism, the respective cables will be pulled uniformly tighter.

[0057] Ballast water is discharged by a suction pump and the flood valves are closed. When so released, the hull will slide to its place and tendons tensioned between power plant and seabed. The hull will thereby be buoyed to its position at near of water s surface.

[0058] Power cable 58 is attached to anchor cable 136 from the underside of the hydro- tower power plant to the anchor 30. Also, Power cables 58 run from anchor 138 to carry energy generated by the hydro- tower power plant for consumption.

[0059] In parts of ocean that there is upwelling, in the cases that have enough efficiency we can use this flow as a renewable energy power plant. Renewable and thermal energy can be extract by hydro-tower power plant, because of upwelling, water is motivated for move upward faster than natural movement. In places that there is sinking, higher layer of water is heavier than lower layer of water so if lighter water is heated, water will have faster upward movement. In this method, generally environmental conditions and position to design hydro-tower power plant is very important because this power plant used both of thermal and renewable energy simultaneously. Also sinking is natural possibility to uprising because water in bottom is lighter than in topside.

[0060] Heat could are provided by furnace with fossil fuel that furnaces 144 could located into ships 142, floating encasement, etc. Fig. 12 shows hydro-tower power plant with use of ships 142 as floating furnace. Old and outdated hull of ships 142 like bulker, tanker, etc. can be used and remove propulsion equipment like motor, gearbox, propeller, etc. E ngine and propeller s shaft displace with furnace 144 and pipes 148. P ipes 148 pass through P ropeller s shaft hole 150 and hold by S upportive structure 146. At first sea water pumped from inlet 152 to boiler. Afterwards heated water discharge into interior of power plant by pipes 148.

[0061 ] In this case as in Fig. 12 is shown, fossil fuel furnace 144 is used as hot source. In this power plant we can increase or decrease in combustion measurement also in some situation power plant is turned off or turned on again. This is valuable, because conventional thermal power plant donT have such capability, and renewable energy like solar and wind basically are uncontrollable.

[0062] The Hydro-Tower Power P lant with solar energy collector that concentrates solar energy to heat a working fluid. This fluid is pumped to circulate through coils to heat water to drive the upward current (not shown). Instead of collector, a flexible dark layer with materials of rubber, straw, etc. that is in undersurface of sea can capture solar energy. This heated water can be used as heating source, especially in low latitude (not shown). [0063] While the disclosure refers to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. In addition, many modifications and variations of the invention will be appreciated by those skilled in the art to adapt a particular instrument, situation or material to the teachings of the disclosure without departing from the spirit thereof. Therefore, it is intended that the disclosure not be limited to the particular embodiments disclosed.
