¿Por qué aumentan los dolores de cabeza en adolescentes.. In recent decades, England, EU, USA, Canada, Australia and Japan have spent huge amounts of money in the development of new sources of renewable and non- polluting energy, particularly in energy converters of waves (Wave Energy Converters “WEC”) and ocean currents, based on the current state of the art and using the most promising types of technologies to capture the energy from waves, ocean currents and rivers among which stand out the oscillating water column, Pelamis, the pendulum, Wave Dragon, Archimedes Wave Swing and IPS OWEC buoy as well as different types of tidal turbines. US 5,789,826 (Bogumil) discloses an improved system for harnessing the energy of ocean waves to produce useful energy like electricity wherein a power generating apparatus is attached to a support structure located out of the water and on dry land. The support structure comprises a mechanical boom disposed on a base located on the shore and a moveable mounting structure provided with a plurality of hydraulic cylinders such that the power generating apparatus may be moved in all directions and placed in position in the water flow optimal for the generation of power.

The generating plant (1 10) for converting the kinetic energy contained in ocean water currents comprises at least one anchored cable (1 1 1 ) at the seabed, which must maintain the position of the plant and must resist the tension generated by the ocean current on the at least one converter device (100) for converting kinetic energy from unidirectional fluids. The preferred configuration for the converter plant (90) which converts electric energy from the energy contained in shallow water currents, involves the use of the following elements: a plurality of rigid fluid deflectors (1 ) (see Figure 3- C), rigid or mounted on a shaft (3) that allows it to move between the limits (1.1 and 1.2) and additionally a shaft (4) with its respective guide rollers (5) without freedom of movement between the adjustable limits (1.1 ) and (1.2); at least one kinetic energy converter module (see Figure 6-A, B) (50), for extracting the kinetic energy contained in water currents, with fluid deflectors (1 ) placed perpendicularly with respect to the level and in the direction of the water current; at least one floating structure anchored to the seabed (see Figure 8-B); at least one adjustable counterweight (98) to maintain the perpendicularity of the energy converter module (50) with respect to the sea level and at least one guide or position stabilizer (99) to maintain the perpendicularity to the direction of the water current.

The preferred configuration for the waves kinetic energy converter plant (70) involves the use of the following elements: plurality of rigid fluid deflectors (1 ) (see Figure 3-B) flat, balanced, mounted on a shaft (3) which provides it with freedom of movement between the limits (1.1 and 1.2) and additionally a shaft (4) with at least two guide rollers (5) with freedom of movement between the adjustable limits (1.1 ) and (1.2); at least one generic kinetic energy converter module (30), (see Figure 4- A, B) implemented to extract the kinetic energy of waves, including the set of elements (41 ) aimed to resist the horizontal force generated by the capture of wave energy (see Figure 5-A, 5-B); at least one wave kinetic energy converter device (60); a waves kinetic energy converter plant (70) which converts kinetic energy into electrical energy (see Figure 7-B), comprising at least one buoy (72) anchored to the seabed by means of at least one anchor, ballast or anchor located at the seabed (71 ), connected by means of at least one tension cable (77) of sufficient length that allows free movement of at least one buoy (72) when facing tides change and the passage of the waves.

Art Threads: Wednesday Sewing - Leaf Motif Free Motion.. The plurality of fluid deflectors (1 ) returning by the upper part of the wave energy converter device (60) could be active if they have their respective limits of movement (1.1 ), (1.2), on the contrary they would be inactive since they would have total freedom of movement. This generates an device for capturing energy from waves (60), as shown in Figure 7-A. In order to make the combination of floats with ballast more effective, it is necessary to have a horizontal structure which distributes the force exerted by the passage of the waves in an even way on the waves energy converter module (40). It is also possible to improve the stability of the leveling of the wave energy converter module (40) with regard to the sea- level by means of at least one collapsible or elastic, flexible float collapsing when being subject to pressure exerted by the passage of the wave, decreasing its volume, thus displacing less water, and decreasing the local force of the wave onto the structure.

In this case, when the current of the water flow has a single horizontal direction, the at least one second shaft (4) with at least two guide rollers (5) of the fluid deflector (1 ), during the travel of the fluid deflector (1 ) in a direction is supported only in one of the travel limits, (1.1 ) or (1.2), wherein said fluid deflector (1 ) is displaced perpendicularly to the flow. In figures 3-A and 3-B and 3-C the travel limits of fluid deflector (1 ) can be adjustable, in order to control the energy capture variables of the system. Figure 3-A illustrates a fluid deflector (1 ) that moves freely between an upper limit (1.1 ) and a lower limit (1.2), wherein the fluid deflector (1 ) rests without sliding on the the limits of the displaced distance in both directions.

At this distance the sea is deep enough to prevent the clash of the wave with the seabed, resulting in significant loss of energy to the waves. In order to capture the kinetic energy contained in the waves, the preferred embodiment is an installation in deep-sea where the site is located at a distance from the coast in the order of seven kilometers, which prevents the visual impact and interference with other marine activities from happening.

The second preferred embodiment comprises a current kinetic converter plant (90) for converting the energy contained in shallow water currents (see Figure 8-B (90)) and having constant and significant variations of water level, such as currents generated by tides in both directions. The aforementioned can be achieved in several ways, the first alternative is to install the generic kinetic energy converter module (30) on pillars embedded in the seabed being adjusted by height so as to compensate for variations in the tides, and thus annulling vertical and horizontal efforts (see Figure 2 -A (10), 2-B (1 1 )). The second alternative is to install the converter module (40) of wave energy on floats by fixing the height by means of adjustable cables anchored to the seabed.

To capture the energy from waves, the devices of the current state of the art mainly work by means of the exploitation of the vertical and point or multi-point motion of waves, that is transmitted to a hydraulic piston, or the water from the wave can act directly as a piston in an air chamber; and it is also possible to take advantage of the vertical motion of waves to stimulate an electric coil which directly generates electrical energy. In these large spaces plants of great length can be installed where it is possible to capture the wave energy that affect directly on the devices and also the waves that initially pass between the devices and progressively migrate to the devices installed in these areas.

The fluid deflector (1 ) incorporates a shaft (4) with at least one guide roller (5), which moves inside the guide rails (51 ) or they can also be at least two guide rollers being displaced outside of the guide rail (51 ). The adjustment (31 ) of the plurality of fluid deflectors (1 ) allows to arrange said fluid deflectors (1 ) in the same direction as the fluid to stop the operation of energy capture. In the case of a complete operation of both sides of the endless belt (20) and of ascending (7) and descending (8) flows, it is necessary that the amplitude rail limit (34) engages with the amplitude rail limit (36) by means of an extensible rail (38), which allows controlling the amplitude of both rails (34) (36) separately.

This setting can be applied when the horizontal movement of fluid deflector (1 ) is equal to the horizontal movement of the upper limit (1.1 ) and/or (1.2) of the lower limit. This plant comprises at least one anchor (1 1 1 ) connected to at least one buoy (1 12) which in turn is connected to at least one cable (1 13) to the at least one platform (1 15). Also from the at least one buoy (1 12), by means of at least one cable (121 ) is connected as a tensor to the at least one device (100) for capturing kinetic energy from unidirectional fluids.

In addition to maintain the buoyancy of the plant, there is a buoy (1 12) attached to at least one anchored cable (1 1 1 ), where the buoy (1 12) is aimed to absorb the vertical component of the tension generated in at least one anchored cable (1 1 1 ). In this way, said buoy (1 12) is connected by means of at least one cable (1 13) to the platform (1 15) of a plant (1 10), said cable exerts a horizontal force between said buoy (1 12) and said the platform (1 15). Dolor muscular lumbar . The platform (1 15) maintains its buoyancy by means of at least one float (1 14), which must support the weight of the engine room (1 16), the weight of the platform itself (1 15), the at least one device for capturing the kinetic energy (100) from unidirectional fluids including counterweights and structures, and the components of vertical forces that originate in the process of capturing the kinetic energy from the ocean current.

Most part of the worldwide electric energy is generated from non-renewable energy sources, such as coal, oil and natural gas, which emit carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (03) and mercury (Hg) as products of combustion. US 6,476,51 1 (Richard et al.) discloses an apparatus for extracting power from ocean waves comprising a number of buoyant cylindrical body members connected together at their ends to form an articulated chain-like structure. The fluid deflector (1 ) displaces horizontally both in the upward flow (7) direction and in the downward flow (8) direction.
