WAVE TURBINE OPERATING OUT OF WATER ON THE PLANE PERPENDICULAR TO THE INCOMING WAVE

[1] This invention is a mechanism designed to generate electrical energy from the waves in the seas and oceans.

[2] Waves formed in the open seas under the influence of the wind reach the shores periodically like heart beats and lose their effect by hitting the shore. Mankind has always been aware of this resource with a high potential, however an effective method to provide the energy in the waves to the energy market with a competitive price could not be developed until our day.

[3] If we are to mention some of the more seriously considered methods proposed until now , we can say that these are in essence tools to convert the pulsative effect of the waves to rotational motion . In the type called OWC, the air in large structures erected on the shores is compressed under the effect of incoming waves and rotate the Wells turbine connected to a discharge path - rotated always in the same direction with both the incoming and the return air. In other systems, we see in general an attempt to convert the rising-lowering the waves cause on the water surface while traveling into rotational motion. Designs that attempt to generate energy by accompany by twisting like a snake the changes in the form on the water surface caused by the waves have also been proposed. However until now no design could reach the competitive capacity that would provide commercial success.

[4] The mechanism subject to our invention, on the other hand unlike any other previous design, comprises blades that will conduct partial circular motion on as plane perpendicular to the direction the wave travels on the surface of the water - with the crashing effect of the wave and out of the water - (figure 1, front view 1 and 2). What is meant by partial circular motion is the following: since the incoming waves are perpendicular to the direction of arrival and at the same time we will select the rotation axis of the blades at the level which is very near the incoming waves the plane on which the blades (1 and 2) - with suitable aerodynamic curvature - that will move with the crash effect of the incoming wave will be, partially above the level of calm water (in air) and partially below the level of calm water. The mechanism that is subject to our invention has been designed for the blades to rotate always out of the water and in the air. Thus the blade/or blades will be able to rotate faster out of the water in contrast to being in the water.

[5] In other words the blades will never complete a full circular turn, in other words will never fall below the level of calm water (3). Thus we can define the "Partial" circular motion of the blades as "any amount to be realized in the air".

[6] For example if, to a blade which has the aerodynamic shape to rotate in the counterclockwise direction at the moment it contacts the wave coming from across (figure 2, blade A), we add a second blade (figure 2, blade B) - with the aerodynamic shape to start rotating in the clockwise direction this time at the moment it contacts the wave coming from across at a position exactly above and adjacent to the first one and the rotation axis of this blade is very near the water surface, we will have built a blade system that can make a "partial motion of half circle rotation" outside the sea and in the air (figure 1, front view; figure 2 profile).

[7] As known, whether the blades operate in the water or the air, they are components that have the aerodynamics to make a circular motion on the plane perpendicular to the direction of movement of the fluids in motion. If we are to take a cross section of any blade and look at it from the profile (figure 2) we see that it looks like a triangle with a right angle on one side (blade A or B). When a force is applied from across in the direction of the rotation angle on the curved edge of the blade by any fluid, it is the curvature of this edge that makes it rotate around its axis. Depending on the direction of this curvature the blades can be designed to rotate counterclockwise or clockwise. If we fix two separate blades that have the curvature to rotate on the clockwise and the counterclockwise direction in a suitable manner and one on top of the other (figure 2; 1 and 2; blades A and B) in this case we have defined the blade system for the said mechanism. These blades use a mutual rotation axis. We call this the main rotational axis (4) of our total mechanism (figure 1). We call the base that carries the main rotation axis and all the components including the blades on it the tower (5) (figure 1, 2). The tower is a vertical column partially under the water surface and partially above the water surface. This tower does not ever need to be as high as the towers of wind turbines. The tower, depending on how far our turbine will be positioned from the shore - in other words, based on the amount of water depth - has a height sufficient to be installed soundly to the sea bottom. However, still because a fairly little height will be needed above the surface of the calm water, we can say the general height of the tower will be reasonable and sensible.

[8] After building our system on this basis in general when we look at our system from across (towards the shore from the horizon) (figure 1) the scene we will see: a tower (5) the top of which can be seen very little because a large part is under the water, the main rotation axis of our mechanism at its very top (4) and two blades (1 and 2; blades A and B) set one above the other lying in the horizontal direction from the main rotation axis - just above the level of calm water -; in other words the surfaces of the blades that will meet the wave. Here it should be noted that the distance of the main rotation axis of the system (4) from the calm water surface should be at minimum as much as the width of each blade. If the main rotation axis -distance of the calm water- is more than the width of each blade (for the position of the blade parallel to the ground) a space between the bottom edge of the blade and the calm water surface will be formed, however this space should not exist or should be at minimum because if there is a large space between the lower edge of the blade and the surface of calm water, the optimum wave-blade contact cannot be obtained. The best is not to leave such a space. Again, due to the fact that the blades one above the other (1 and 2) have opposite curvature compared to one another, it is very important that the "maximum expected wave height" in the area the system will be constructed will never exceed the connection point of the blades. In order to ensure this the width of each blade should be equal or greater than the maximum expected wave height (6) in that region. In addition it may also be prevented that the incoming wave crashes against both the blades simultaneously by varying from time to time the height of the tower (depending on weather conditions), because we want the wave to crash against the blade that is just above the sea level. Otherwise the efficiency of the system will fall or the system will not operate at all (due to the rotation of the blades in the opposite directions).

[9] As can be seen from this description when the wave that is coming towards the shore from the horizon crashes against the blade that is lying lengthwise just above the sea level it will cause it to rotate -in the air - for approximately 180° and position itself on the other side and in this case when another wave comes - due to the curvature of the other blade on the opposite direction - our blade system will again rotate for approximately 180°. At the end of every half rotation the bottom blade moves up and the upper blade moves down.

[10] In this example the "partial rotational motion range" has been selected to be 180°.

Because the two blades have opposite directions of rotation every incoming wave rotated our blade system approximately half a circular turn and these rotations are exactly like the wipers of the automobiles in one direction and then in the other direction every time.

[11] As can be seen a half cycle rotation (approximately or accurately) of the dual blade by each wave is described according to our sample system. When the blades arrive at the opposite position at the end of the half cycle, they will be able to complete the cycle only with the second wave. Thus it can be said that for each cycle of rotation of the main rotation axis a minimum of two consecutive waves are required. With complementary electronic systems the arrival frequency (period) of incoming waves should be calculated and coordination should be obtained between the blade rotation speed and the wave period with the aid of breaking mechanisms. To clarify: after the first wave hits the first blade (blade A) and sets it in motion the said blade A should complete its half cycle -for example - at the exact time the second wave meets the second blade (blade B). Just after and without disruption the second wave should set the second blade (blade B) in motion to rotate it in the opposite direction. In other words the time between the first wave and the second wave should be -approximately - equal to the duration of each 180° half rotation.

[12] Thus we obtain two uninterrupted rotation cycles - even though in opposite directions - from two separate waves and in total one rotational cycle for every two waves. Naturally a turbine thus rotating should have a connection to the power generation unit (generator) that needs a continuous rotational movement.

[13] Then, with all this description detailed, is it possible that waves -if to use an appropriate term - "fly" the dual blade system mentioned that is tens of meters long and weighing hundreds of kilos at the moment they hit: If the mechanism subject to the invention did not contain any other auxiliary mechanisms this would either be not possible at all or a very limited and inefficient movement would be in question. Thus we must start to describe the details of the pump system that is the indispensable part - one that we could call its heart - of the mechanism subject to the invention:

[14] Let's consider a concrete column 20 meters long, very smooth but at the same time very heavy. If we lay this concrete column which probably weighs hundreds of kilos on a smooth surface on the ground and then hold it with our hands on any end and try to lift it what would happen? Possibly even the strongest man on earth could not lift this column higher than his height. Or is it possible for a very strong person to "fly" this column in the air rotating around the other end by hitting one end with his fist? Then let us answer this: if we were to succeed in erecting the same concrete column, this time perpendicular to the ground, on a smooth surface in an "erect" position -against gravity and observe whether a small child can topple this column by "touching" it what would the result be? Probably however long or heavy the concrete column - proportional to the accuracy of the balance and the difficulty of erection - it would easily topple over.

[15] Starting with this example we can describe easier how the waves can "fly" our dual blade system similar to a heavy concrete column: If we can "justbalance" our dual blade system (1 + 2) around the axis of rotation (4) and throughout its total circular route in terms of gravitational and rotational moments at every point without exception we will provide the last important detail related to our system.

[16] Let's turn back to the concrete column. When we lay it on the ground, let us look at the factors that make it difficult even to set it moving: naturally the force resulting from the weight of the concrete column and gravity but before that and most important is that the concrete column needs to be balanced in terms of gravitational and rotational moments from the other side relative to a point operating as the axis of rotation of the concrete column because when we position the same concrete column this time vertically and just balanced we can easily move it! Why? Because in this case the point of contact of the concrete column with the ground acts as a suitable axis of rotation and additionally the concrete column is simultaneously in total balance in terms of forces resulting from its weight and gravity. Thus such obtaining such balance condition during an operation interval of - for example for half a cycle - and at every point on the operation cycle provides us - in our mechanism example - "an easily movable blade system" and there are certain means to obtain that: one means is the balancing of the blades against the axis of rotation using "mass counterweight" but we do not want to use that method in our mechanism. Even more we do not at all want to use a second blade system equivalent - in terms of mass - to our blade system on the direct opposite direction to the rotation axis because then it will not at all be possible for our blade system to operate continuously out of the water.

[17] In the mechanism subject to the invention a closed circuit pump system has been used that will balance our dual blade system at every point it covers throughout the operation range that will take place outside the water and around the axis of rotation in terms of turning moments. With this pump system in order to balance the blades around the axis of rotation in terms of rotational moment and/or moment of inertia, there will be no need to use any "mass" on the opposite side of the axis of rotation relative to the blades. The need to balance the blades in terms of rotational / inertial moments still exists, however this time with the aid of the pump we have moved the mass that will balance the blade (because the blades are on top of one another in our mechanism we can also call it the "blade") to outside the plane of rotation.

[18] On the main rotation axis (4) of the blade (1 + 2, figure 2) and behind the blade one action pump (7) of suitable design containing hydraulic fluid has been placed. A second pump of again a suitable design has been needed for our purpose which we call the reaction pump (8) (figure 5). Other joint types of suitable design of the action and reaction pumps may also be used for the balancing of the blade in terms of rotation/ inertial moments in the plane of rotation and without using mass across the axis of rotation. Thus the number of pumps is reduced from two to one as well as more than two pumps can be used for a more effective result. Whatever their number our purpose in using pumps behind the blade is to take the weight needed to be used across the axis of rotation of the blade to a position outside the plane of rotation of the blade.

[19] According to our sample design the action pump (7) is places behind the blade to be on the axis of rotation of the blade and the reaction pump (8) may be placed at a separate location (for example out of the sea, on the coast, in the forest etc) (figure 4 and figure 5). The internal structures of the action and reaction pumps and their functions are very similar (figure3, figure 4 and figure 5). If we are to take each pump we will see that its vertical cross section consists of two cylinders, one inside the other (figure 3). We should consider the inside of the inside-cylinder as full, in fact from its center the main axis of rotation of our total mechanism passes (figure 3). When we look at the section of the pump there is a filling mass like a half moon between the part we name the outer-cylinder (9) and the part we call the inner-cylinder (10) Thus we can say that the space between the inner and outer cylindrical layers of the pump is partially filled with the filling mass (11) and the remaining part is empty. We call that space the "action pump hydraulic room (17) for the action pump and the "reaction pump hydraulic room (18) for the reaction pump. The filling mass (11) that takes up a portion of a little less than 180° a circular cross section - based on the vertical cross section - tightly fills a portion of the space between the outer (90) and the inner (10) cylinders of the pump. The portion of the outer and the inner cylinders that remain from the filling mass and that corresponds to a little more than the value of 180° -based on the cross section - is empty and contains the hydraulic fluid of the closed circuit system (17 and 18).

[20] Between the empty space which will contain the hydraulic fluid and the filling mass

(11) connection has been made at two points. On the both sides of the filling mass that face the hydraulic fluid (the space between the outer and inner cylinders) is a hole each. In our example because these holes are two per pump they are a total of four in number for the action and the reaction pumps. (12, 13, 14 and 15). If we are to look at the cross section of the action pump (7) cross section (figure 3), we call the hole of the filling mass (11) which is on the opposite side (on the left) of the blade (1+2) when the blade is on the right-hand side the "action pump, discharge hole (12) and the hole on the side of the blade the "action pump, suction hole (13)". Here it should be noted that the filling mass (11) of the action pump (7) fills the lower half portion of the action pump when looked at the vertical cross section (figure 3 and figure 4).

[21] Similarly if we are to look at the vertical section of the reaction pump (8) (figure- 5), we see that it also contains a filling mass. However the filling mass (11) of the reaction pump - when looked at the vertical cross section - fills the upper half of the reaction pump. While the action pump (7) is the pump mechanism connected with the blade (1+2) the reaction pump (8) is the pump mechanism connected to the counter mass (16) (figure 5).

[22] In the previous description it was mentioned that in order to balance the blades (1+2) around the axis of rotation in terms of rotation/inertial moments methods would be utilized that are outside the known methods. To review the known methods of balancing any blade in terms of the rotational/inertial moments, the first and the best known of these is to use multiple blades around the axis of rotation (two, three, five, ten, twenty etc.). For example for wind turbines, in general three blades at equal angles are used. Another known method is to use a "counter weight" on the opposite side of the axis of rotation of the blade even though a single blade is used. Whatever the method, a selection is made regarding the number of blades to suit the purpose of the system and the blade is then balanced around the axis of rotation for moments of rotation/inertia with one of the methods mentioned above.

[23] Then why don't we use these methods in the mechanism subject to the invention? If in our mechanism we were to use more than one (two, three) blades (positioned at equal intervals around the axis of rotation) as in the wind turbine -for example - we could not obtain one of the main goals of our system, ie. "driven by the wave but still operating out of the water" because when blades of more than one are used there is an active component (blade) in both halves of the circular plane in which the blade rotates (both semi circles). On the other hand in the mechanism subject to the invention nearly half of the circular plane in which the blade will operate is under water (sea). We, however, want to operate our blade in this mechanism only outside the water. Thus in the mechanism subject to the invention the blade cannot be balanced for moments of rotation/inertia with any other blade (or blades) opposite on the axis of rotation.

[24] In this case let us look at the other alternative: we could well balance our joint blade

(1+2) that will be driven by waves but still make the rotation motion outside the water with a mass (like a mace) that we would place just opposite the axis of rotation! However we would face some serious problems in that case: firstly we would need to contain a weight much heavier relative to the mass of the blade continuously - in every stage of production and use. We can balance a blade that is tens of meters long and weighs hundreds of kilos only by using a weight of tons. Even if we were to accept that, this time we would never be able to operate our blade (as considered as a whole together with the counter weight) out of the water: while the blade (1+2) continuously moved in and out of the water the weight across the axis of rotation of the blade would go in and out of the water too! That would lower the efficiency of the system due to the strong water movement caused by the aerodynamics of a counter weight mass shaped like a mace and possibly render it inoperational. For these reasons the blade (1+2) in the system subject to the invention has been balanced with a counter weight (16) that has been moved outside the plane of rotation of the blade. To turn back to the action and reaction pumps we have stated that the reaction pump (8) also contained a filling mass (11) similar to the action pump (7). When a vertical cross section is taken (figure 5) the filling mass (11) that is on the upper half of the reaction pump is in contact with the space that contains the hydraulic fluid in the pump same as in the action pump. When the vertical cross section is viewed, for the case where the counter weight (16) is on the right hand side of the reaction pump we call the hole on the left hand side of the filling mass of the reaction pump the "reaction pump, discharge hole (14)" and the hole on the right hand side of the filling mass the "reaction pump, suction hole (15)". [25] All these holes that are mentioned in the action pump and the reaction pump (figure

4; 12, 13, 14 and 15) are necessary for the hydraulic fluid in the pump to enter and exit the spaces reserved for it in the pumps. The holes in the internal structure of the pumps and starting on the surface between the hydraulic fluid space and the filling mass - eventually - exit the pump form any of the circular lateral surfaces of the pumps with a cylindrical structure that correspond to the bases. Thus for each pump (As seen from the outside) there are two holes (a total of four holes for the two pumps), one for discharge and the other for suction.

[26] The holes that are two in number per pump are connected to each other with a total of two tubes - of suitable properties - to form a "closed circuit hydraulic system". In the closed circuit hydraulic system, the tubes that will connect the two pumps (7 and 8) to each other are firmly fixed to the pumps and the holes on the circular bases of the cylindrical pumps of the holes that are two per pump (for the entry and exit of the hydraulic fluid). This connection is as follows (figure 6):

[27] One end of the first of the total of two pipes is connected to the "action pump, discharge hole (12)" and the other end to the "reaction pump, suction hole (13)" One end of the second tube is connected to the "action pump, suction hole (13) and the other end to the "reaction pump, discharge hole (14). The principle is to ensure sealing to form a full closed circuit with the connection of the "action pump hydraulic room (17) and the "reaction pump hydraulic room (18)" to each other in the tubes and the tube-hole connections.

[28] Another of the internal structural elements of the pumps is the pistons. In our example pump system two pistons, being "the action pump piston (figure 3 and figure 4, 19)" and the "reaction pump piston (figure 4 and figure 5, 20)" have been used. The pistons should move in the hydraulic rooms (17, 18) inside the pumps. However during these movements the pistons should separate the hydraulic rooms exactly into two sections and should definitely not limit the passage of the hydraulic fluid between the two sections. In other words, the morphologically, the piston should have a structure to fit tightly in a section of the hydraulic room it is in however should not limit its own movement. While the pistons move inside the hydraulic room they direct the fluid in the hydraulic room to the suction of discharge holes (12, 13, 14, 15). In order for the piston to be acted on by forces outside the pump there should be a point of contact open to interaction external to the pump however it should be ensured that the hydraulic fluid does not leak out. For that purpose a duct has been made on the middle of the cylindrical outer surface (9) of each pump (figure 6). This duct, in essence, continuously splits the outer cylinder (9) of the pump which has a cylindrical morphological structure and separates it into two parts. The internal cylinder of the pump (10) on the other hand, is sufficient to provide the integrity of the pump. [29] There is a ring (21) that is capable of free rotation by sliding inside the external cylinder (9) two forming a continual integrity with this duct that splits the outer pump cylinder and that does not permit leakages of the hydraulic content. This ring (21) in order for it to go up and down together with the piston that is going up and down in the hydraulic room is firmly fixed to the piston (19 or 20). The contact point of the pump for the transfer of the external forces to the internal structure of the pump is called the pump tuber (22). This tuber - same as the firm fixing of the piston to the ring from the inside - is firmly fixed to the ring from the outside. Thus the movement of the piston - on the condition that the hydraulic fluid does not leak - means the ring and the pump tuber always move the same way...

[30] We have previously mentioned that in our example pump system the blade (1+2) will be connected to the action pump (7) and the counter weight (16) will be connected to the reaction pump (8). The name of the place for this connection on the pump is the pump tuber (22). One pump tuber has been found necessary for each pump in our example.

[31] In order to complete the interaction between the action pump (7) and the blade (1 +

2), the blade connection (23) between the tuber of the action pump and the back face of the blade is established (figure 2). We have already stated that the action pump is located just behind the blade and on the axis of rotation (4) of the blade and the whole system. In fact the main axis of rotation (4) behaving as the "filled internal cylinder (10)" of the action pump (figure 1, figure 3 and figure 7) forms in a way the internal cylinder of the action pump Then, if we are to look at our system from the side (profile) (figure 2) there should be a very short distance between the back surface (not in contact with the waves) of the blade and the action pump just behind it. Now, if we are to make an indentation on the back surface of the blade and insert a rod along the axis of rotation in parallel to the axis of rotation and then connect this rod to the pump tuber (22) just a bit away we would provide the coordination of movement between the blade and the pump. In the light of this discussion, we can say that the rotation of the blade (1+2) (figure 1 and figure 3) means, in fact the rotation of the piston of the action pump (19) - simultaneously and with the same angle - as well.

[32] When a cross section is taken, for the position of the blade which is on the right hand side relative to the action pump and parallel to the ground (figure 3) the action pump piston (19) is on the right hand side inside the "action pump hydraulic room (17)". At that moment if the blade starts to rotate from the right to the left, a positive pressure is formed on the hydraulic fluid on the left hand side of the action pump piston (19) and a negative pressure is formed on the hydraulic fluid behind the action pump. Thus an external force forces the blade to rotate from this position - parallel to the ground and at the right - to the left (counterclockwise) there would be a hydraulic discharge from the "action pump discharge hole (12) and an entry of hydraulic into the pump from the "action pump suction hole (13)". Since the system is a closed system -as described previously - and the pumps are connected to each other via tubes, the hydraulic fluid leaving from the "action pump discharge hole (12)" will enter from the "reaction pump suction hole (13)" (figure 6). Similarly due to the negative pressure formed on the volume behind the action pump piston (19) the hydraulic fluid that should enter from the "action pump suction hole (13)" will arrive via the tube coming from the "reaction pump discharge hole (14)". Naturally for all this to be realized with ease throughout the operational range of the blade the hydraulic pressure inside the both pumps (7 and 8 ) should continuously stay neutral before and behind the pistons (19 and 20) instead of fluctuating between negative and positive. That can be possible only by connecting the reaction pump (8) with a suitable counter weight (16) mass (figure 4, figure 5 and figure 6). The counterweight should have a mass to perfectly balance the moment of rotation/inertia that the blade will create.

[33] We have stated that the duties and the internal structures of the action and reaction pumps were very similar. In fact if we leave aside the fact that the filling mass (11) of the action pump is on the lower half of the action pump and the filling mass of the reaction pump is on the upper half of the reaction pump we will observe no other difference. However arrangements that use a larger reaction pump can be made in order to be able to use less counterweight because it will be easier to balance the moments of rotation/inertia by increasing the diameter of the pump or by increasing the length of the pump tuber.

[34] The connection of the counterweight (16) to the reaction pump tuber can be made by various methods. The counterweight is either directly installed on the pump tuber, thus the counterweight rotates around the center of the reaction pump -and together with the reaction pump tuber - around its circular orbit. Or a circular orbit (24) is prepared for the counterweight - with its center being again the center of the reaction pump; the counterweight easily slides and moves along this orbit (figure 5) A suitable contact is provided between the counterweight - reaction pump tuber and thus -exactly as in the example of the action pump and blade - the counterweight and the reaction pump move always in coordination. In our sample system the length of the circular orbit prepared for the counterweight is approximately as long as "the semicircle".

[35] In order for the counterweight (16) and the blade (1+2) to balance each other at each point along the orbit of the blade for the moments of rotation/inertia the most suitable mass of the counterweight should be selected based on the length and the weight of the blade. Due to the fact that for the position of the blade on the right hand side of the action pump and parallel to the ground, the counterweight is at the same moment on the exact right hand side of the reaction pump and at this time the filling mass of the action pump is in the lower semicircle and the filling mass of the reaction pump is in the upper semicircle the total pressure that the blade and a counterweight of a suitable mass on the closed circuit hydraulic fluid - due to gravity - is neutral in total. This means that the blade is "passive" in terms of the moment of rotation/inertia around its own axis of rotation and at each point it stops in the operation range: exactly as in the moment a twenty meter concrete column is vertical to the ground by just balancing it!

[36] In the mechanism subject to the invention in order to obtain the balance described the

"property of pressure transfer of fluids" have been utilized. Then in order to generate electrical energy from sea/ocean waves different number or shape blade(s) may be used within the frame of the same principles and these may be balanced with counterweights of different types with or without orbits. For example another blade system shaped like and L and not set on top of one another but still single piece and with different direction of rotation is balanced using the principles described and using counterweights this time the blade system may come and go outside the water in a 45° partial rotation range Or with the help of a completely different type of pump a single blade that is again balanced with a counterweight that has ben moved to outside the plane of rotation, which has a single direction of rotation - without ever having a clockwise and counterclockwise rotation directions - by only rotating in one of these directions may make possible the construction of such a mechanism. For example let us consider that a single blade with a single direction of rotation is balanced with another type of pump and within the described principles: let's consider that when the wave will hit the blade and moves it -for example - 30° for a moment the balancing of the blade with a counterweight is "omitted" thus that the blade -due to gravity- falls on the water surface then it is again balanced with the counterweight - immediately in some way - and that it again moves 30° with another wave. In this case designs that can complete a 360° circular rotation with 12 consecutive waves by moving from its place 30°, then falling on the water surface, then again moving 30° with another wave. Or other operational ranges larger or smaller than 30° for the blade may be determined...

[37] This way our blade is able to rotate in the direction perpendicular to the plane in which it makes the rotation motion with a force applied from across by any fluid (eg. Water). The electricity generator unit to be connected on the main axis of rotation of the system with a suitable connection between the blade and the action pumps will complete the mechanism.

[38] This mechanism can be used to generate electrical energy from sea / ocean waves.
