DOUBLE PHASED WIND-WAVE MOTOR

Abstract: This three-dimensional, two-phased wind-wave converter consists of two groups of buoys in a construction that places each group in a phase difference of half a wavelength, so that the relative energy between these two groups are absorbed by three or more hydraulic pumps. Further more it absorbs the rolling multi-dimensional energy from all directions continuously, with the result that the level of efficiency increases four to five times compared to other solutions. With that, the price of energy can drop to several times lower than those of the competitors. The durability is also strong by the fact that these two groups utilise the energy without employing moorings as a counter force. This provides substantial stability in adverse weather conditions. It can be used for power production as well as a water pump.

Description: DOUBLE PHASED WIND-WAVE MOTOR Description It is crucial that a wind-wave converter retains a level of high efficiency in relation to production costs, and that it will remain stabile and durable in rough weather. Previous patents and projects convert energy from only one wave at a time, and in such a way that only a fragment of this energy is utilised. Previous solutions have not proven strong enough or stable enough in adverse weather conditions. This invention solves both these problems by utilising the relative energy between two waves simultaneously. Thus efficiency is improved considerably. The stability is also completely different, due to the moment of force from the one wave being neutralised by the other wave. This energy does not, as is ordinary, pass over into moorings or stabilising mechanisms. Rather, this invention works in such a way that continuously, while the water moves toward the first group of buoys, the other group of buoys are driven by another part of the wave, with the difference of half a phase, in precisely the opposite direction, in such a way that the total energy is absorbed by the mechanism. This yields force and effect. The wind, too, supplies energy directly to the system owing to this unique construction permitting the buoys to roll horizontally with the waves. The physics of waves operates with four dimensions; the dimension of time and the three dimensions of space. The force vectors in a wave in the water rotates around an axis parallel to the crest of the wave. We obtain the same motion if the time dimension is exchanged with a length dimension in the line that is perpendicular to the crest of the wave. In other words; at any given moment, such as in a photo for instance, the force vectors along this line are in equal rotation, but as a function of length rather than time. It is precisely on the basis of this equality that the wind-wave converter is constructed; by placing two groups of buoys (1-4-5) and (2-3) at a set distance, we obtain a particular phase difference, in this case 180 degrees in angle difference to the force vectors. Exactly how the wind-wave converter works is described in greater detail below. This three-dimensional two-phased wind-wave generator consists of two groups of floating buoys (1-4-5) and (2-3), that by means of their unique construction continually absorb the relative energy that exists in two opposite wave phases. Each group of buoys (1-4-5) and (2-3) follows the direction of the circular movement of water, but with approximately half a radius in relation to the water, because it is the difference in the velocity of the water in relation to the buoy that provides force and produces energy. The first of these two groups consists of three connected buoys (1-4-5). The forward buoy lies along the centre line, perpendicular to the crest of the wave, and is hit by a wave a wavelength earlier than the other two buoys (4-5) in this group. These two buoys are in the wave behind, at a wavelength's distance. The two other buoys (4-5) in this group are placed furthest out in relation to the other buoys. Each of these two buoys has half the volume and weight of what each of the other three buoys have. Thus the centres of gravity for the two groups are in approximately the same place. The whole system is in equilibrium. The other group of buoys consists of two (buoys) (2-3) firmly connected to a construction so that they are the same distance from the centre line which is perpendicular to the crests of the waves, with a reciprocal distance of approximately their own breadth. The projection of all five buoys seen from the front appears to be a continuous surface, because this disperses the energy evenly from the waves to the floating devices by the fact that they do not "block" each other. (The wave decreases, or disappears after having dispersed of its energy). All five buoys have their broadest surface, and a vertical plate below, perpendicular to the crest of the wave. These will always be parallel to the crest of the wave because the whole unit rotates naturally with the waves. Between these two groups are placed, via movable joints (7), three or more hydraulic pumps (8-9) which convert the energy. The horizontal pump (8) takes up all the horizontal kinetic energy that comes from all five buoys. The two vertical pumps (9), placed in a V-shape, take up all the vertical kinetic energy from all five buoys. As these groups roll in an opposite phase, the pumps will steadily absorb the whole energy. To prevent the two middle buoys (2-3) from tilting, there are rods (12-13) to stabilise them. The extreme end of the upper rod (13) is firmly attached to the two middle buoys by gliding around rod (12). Thus the two middle buoys are prevented from rotating round their own axis. Both these rods are connected with a rope or wire that glides round a wheel (10). This wheel is further, via its shaft, moored to shore or some other floating unit along with power cables or hydraulic pipes. Since this shaft is stationary in relation to shore, heavier units such as generators or similar are fitted to it. Alternatively, if weight permits, the actual generators that convert the hydraulic energy to electric power can be mounted to the cylinders (8-9). This due to the middle part of the cylinders being practically stationary in relation to shore. The distance between the centre line between the hindmost and the outermost buoys (4-5) and the first buoy (1) should be approximately the same as the average wavelength. Even though statistics show that this length is relatively constant in one place, it may still vary. This length may then be regulated by hydraulic mechanics that adjust the distance according to the varying wavelength so that the effect is optimal. Not shown on the drawing. As an alternative construction, two pumps placed aslant in a V-shape may replace the horizontal pump (8). Alternatively the pumps may be placed in disparate angles and number between these groups of buoys, though common to all these alternatives, the pumps are placed in such a way that the angles fill in the space. This means that the cylinders lie in different levels that intersect each other. Alternatively the hydraulic pumps may be substituted with magnetic rods. The construction alternately forces together and draws out the pumps or the magnetic rods. An alternative to the hydraulic pumps or to the magnetic rods is replacing these with a rotating axis (16), which directly works one or more generators (17). Since each of the two groups of buoys (1-4-5) and (2-3) rotate equally with the waves in an opposite phase, with a 180 degrees difference, each of these groups are mounted in a bearing unit, placed at 180 degrees difference on this axis, while the axis' centre of rotation rotates within two bearings that are fixed to a construction that is stationary and that contains the generators. On the axis there is a driving wheel that works the generator. The axis can also function as a flywheel, because the centre of gravity is not in motion. Right between the centre between the hindmost (4-5) and the foremost (1 ) buoy, mounted to a frame, there is a bearing unit that surrounds the axis (16) (that rotates inside this). Around the outer part of the axis (16) at both end pieces, there are two bearing units that are connected to the two middle buoys (2-3). The buoys are stabilised by means of a vertical wing (19) mounted some distance below them. This wind-wave converter absorbs energy from the wind when it blows in the same direction as the waves, and supplies this directly to the aforementioned mechanism. It is the wind that builds up the waves, and it is therefore most common for the direction of the wind and the waves to coincide. The wind increases at the crest of the waves, and is more sheltered at the trough of the waves. This fits with each buoy's rolling motion: They are horizontal with the waves and the wind at the crest of the waves, and back to the trough of the waves where the wind is at its calmest. This difference provides added energy for the wind-wave converter. In addition one can construct rotating plates (20) that are mounted to the top of the buoys. These are synchronised half a revolution to the revolution of the buoy, so that the plate is vertical at the top, horizontal at the bottom, and aslant at the sides. In this way it will be pushed in the same direction as the water, and amplify the movement of the buoys. If the wind turns a different direction than the waves, this plate will simply rotate like a weather wane about a vertical axis. Number reference to the drawings. 1. Forward buoy. 2. Buoy 3. Buoy 4.
