FLUID CURRENT ENERGY CAPTURE SYSTEM.
FIELD OF THE INVENTION.- In wind, tlwvial and maritime collectors mini and mega-systems, which generate a large amount of electricity and for housing, agriculture, sea water desalination, water elevation, current feedback to the electricity network, to obtain hydrogen by electrolysis of the water and storage of pressurized air in bags in the sea at great depth.
STATE OF THE ART. The water current energy capture systems in the sea need high technologies and high costs to achieve high performance. They are difficult to control, complex, need to be oriented towards the currents and their energy is difficult to store. Wind systems need high technologies, high costs, placement at high altitudes and high winds to achieve high performance. They are difficult to control, complex, need to be directed towards the wind, visually contaminate the landscape, produce radio distortions, are affected by lightning and kill the birds.
Energy is more expensive than with conventional systems. The invention provides simple, useful, economical, axial, helical and of blades turbines, and the like.
DESCRIPTION OF THE INVENTION
Objective of the invention and advantages.
Get energy from the marine and fluvial currents, which, unlike solar and wind, tend to be more constant and not have great periods of calm. Of large masses of water, such as the Gulf Stream or Kuroshio, in straits, capes and around many islands, where water must pass at a certain speed from one area to another. The water is about 832 times denser than air.
To be able to use turbines, simple, low cost (can be between ten and thirty times cheaper), high power, high performance, minimum cost of kW/h, minimum number of parts, single part, without shaft, without bearings, nor their supports, anchored to the ground do not need masts, a nail or ballast is sufficient, clean (does not affect them or accumulate dirt), do not need cover or casing, large and small dimensions, large length or several in series, they can be inflatable and extendable, operate in line with or inclined towards the current, are valid for both air and water, do not kill birds or fish, protect the ozone layer and the environment, are self-directed towards the wind or current without the use of electrical mechanisms, used submerged are not affected by the destructive waves, and using constant currents eliminates the need to have to store the energy, it would only be necessary a small storage. Without competition in all these characteristics. The most useful and simple are those that have no shaft, blades, twisted beams or flat stocks and flat thread or half-cane springs Problem to solve. Renewable energy is not yet enough productive to use in large quantities,

2 is not constant, produces environmental pollution, and because of its discontinuity needs to be stored. With the present system you can get much and constant energy from the sea and rivers, not needing storage, and can be placed where it does not harm or contaminate as much electrical, audible as visually. In the air, it allows to obtain the energy at high altitudes. Each turbine may use .. one or more helical threads or blades on its axis.
The fluid current energy capture system, consists of axial turbines having one free end and the other or its axis is held to the mechanical element that there is to move or to an electric generator, either directly or through a rpm multiplier. It is held by a pair of links, an angular ball joint, a rod, a joint or a hinge. Generators and mechanical elements to be moved are held to nails, anchors, concrete blocks, mesh bags filled with stones, posts, trees, towers, street lamps, buildings, mounds, or a cable or chain supported between two points of the aforementioned, which enable the turbines to rotate, orient themselves in the fluid stream and capture and take advantage of the flow of said stream, characterized because the turbines comprise helical springs, helically twisted beams or flat stocks, complete helical turbines with their shafts or only their blades, which capture the energy of wind or water, driving its shaft or holding end to an electric generator system, to a mechanical system or to a compressor or water pump, whose regulated flows drive motors or turbines that drive the generators. In all cases, the blades around the axis of rotation of the turbines have an inclination to the wind, which generates a torque in the same direction. The generators only have a small angle of rotation or inclination.
In one variant, turbines are formed by blades wheels connected in series.
All turbines can be cylindrical or conical in shape, and may use one or more blades or threads.
The conical shape gives them more stability.
The turbines may have the same density as the fluid in which they move, or they may have different densities, whereby they may assume some inclination with respect to the fluidic current.
Turbines, their axes or blades besides being hollow and filled with helium or air, can be made of plastic polymer foam such as PVC, polyurethane, polyethylene, etc., with a strong and protective cover, and can act as comets. The hollows can be made of rubber or plastic.
They can be inflatable and flexible. In general, as they are in contact with water and with elements that can be abrasive, must be used, resistant and low density materials, polymers, and carbon or glass fibers with resins.
And in case of using metallic materials, like the steel, they must have a protective layer of zinc. The plastic can be reinforced with graphene and very resistant synthetic fibers, of Kevlar, glass, carbon, etc.

3 The turbine can be fixed to the collar, cardan joint, ball socket, etc. In this case the shaft of the generator or the mechanical device is connected to the rotating end of the turbine by a pair of gears.
Turbines, when they do not have a shaft, consist exclusively of helical blades, helical springs, preferably in half-cane or plane thread, or helically twisted beams or flat stocks. The helical flat thread springs coincide or are the same as helical coils of turbines used without a shaft.
The turbines, blades, helical beams or flat stocks have a proportional performance to their front or cross-section, to the angle forming with the axis of rotation at each point and to its length.
Angles between 25 and 550 can be used. Unlike turbines of this kind that move inside a duct these can greatly increase its power by raising its length. The blades can have two types of inclination: a) Inclination of a section of the blade with respect to the axis of rotation and b) Inclination of a section of the blade with respect to a plane perpendicular to the axis of rotation.
Maximum performances occur at roughly 42 angles.
Especially in the air, the cable can be replaced by a long and simple helical turbine.
The electric generators can be synchronous, and consisting entirely of permanent magnets.
Especially rare earths of samarium-cobalt or neodymium-iron-boron.
As mechanical elements, motor pumps are used to raise water or to drive electric generators, or air can be pressurized and stored in bags in the sea at great depth.
The turbines should preferably be axial, receiving the flow of water or air parallel to their axes and automatically directed them like weather vanes, but may have an inclination to the horizontal, which depends on the difference between the weight of the turbines, including the contiguous installation, generator, and the weight of the fluid that is displaced. When both factors are equal they remain horizontal in the fluidic current. Any type of turbine, with or without a shaft, may be used, especially those which are longitudinally extended and with tilted or helically arranged tilted blades.
In order to increase their stability, their aerodynamic profiles have the dimensions of the turbines, their shafts and / or their blades are greater at or towards the free end.
An axial turbine variant utilizes, with or without shaft, two (or more) inclined blades that can be symmetrical to each other, which create a rotation torque about said shaft.
With the turbines inclined to the fluid flow the efficiency can be even higher since the section of the affected surface is much larger than with the frontal current.
Nevertheless, turbines when they receive the current parallel to the axis, not being covered by a tube, the performance is very high and increases, and the power is multiplied with the length of the same. Since downstream

4 the turbine absorbs or captures laterally the energy of the water stream.
The rotation of several of these turbines can be applied to a shaft supported and driven through the inside of a mast, shaft that can drive a pump and draw water from the wells.
The turbines may have the free end attached to a balloon or to a float.
The turbines can act partially as balloons or floats. In all cases, the turbines, cables, chains, generators or retainer bars may have a density equal to or similar to the medium in which they move. They may have a density between 70% and 130% of that of the fluid, although it is not limiting.
The hollow and flexible turbines, shafts or blades can be made of canvas, plastic or very .. dense mesh, which act as bags and can be kept inflated with the air or water stream in which they are immersed. For this purpose the end of the turbine, which is fastened, carries a fluid inlet mouth delimited by a ring, which is held to the generator rotor shaft by means of cords.
The turbines can be placed in an orderly way, in rows and columns, so that they can use common electrical or water installations and a large surface.
The blades, blades or turbines can be rigid or flexible. Tilting the flexible blades and reducing their impact surface withh the increase of the current speed.
Some turbines anchored at the sea floor can be turned and raised for repair or maintenance. It may be necessary to vary the degree of flotation with a remote control to make its exit to the exterior. This is achieved with an air chamber, which expands for ascent and is compressed for descent.
In the sea the turbines can be placed semi-submerged taking advantage simultaneously the action of the water and the wind.
In the sea, to carry the electric current you can use a single conductive cable, the positive or the phase if it is alternating and the other for the negative, mass or earth using the water that is .. conductive.
In the sea the turbines can carry a floating rope, which is used to raise the system for repair or maintenance. A certain color is applied as distinctive.
On the ground and in the water to the posts or buoys that stand out are applied stroboscopic lights, red or amber, preferably of LED diodes. The electrical supply is made with the same generated by the system Particularly in high-altitude wind turbines, one or multiple turbines can be used in series instead of the holding cable. That being flexible could be a single turbine.

Small-sized turbines are often highly revolutionized and do not need multipliers. The mechanical energy obtained can be used to draw water on land where it is stored at a high altitude, subsequently is regulated and drives a turbine that moves an electric generator.
The generator is held to a support point by a bar and a joint and a collar that allows it to tilt

5 .. slightly vertically and horizontally, but not to rotate around its axis.
This is also achieved with a pair of links.
Radial blades help prevent oscillations due to turbulence or gusting winds.
Generators can supply heating resistors, mobile phones, etc. Resulting in a simple and very economical system.
A control, warning and security system informs the status of each of the devices.
Operation: The weight of the turbine and moving parts is equalized, with the upward displacement of the water or air being discharged, thus the turbine is arranged horizontally, except when the stream of water or air has a certain vertical inclination. However if we want it to be tilted upwards by having its supports on the ground, or tilted downwards to have them in the high water area, the weight of the turbine must be varied to get it. You can use turbines more or less heavy than the fluid, which will be inclined but its performance is still very high. This may be necessary to avoid disturbing the navigation of ships, airplanes, etc.
