Abstract:
An apparatus utilizing wave energy to capture ocean water and send it to shore for hydroelectricity, hydrodynamic energy conversion or desalination. The submerged device is located offshore and is preferably oriented orthogonal to the shoreline or the incoming water surges. Responding to underwater wave surges, a deformable bladder filled with sea water is compressed and the seawater contained therein is expelled and sent to shore. A one-way valve responds to the differential in water pressure inside the empty bladder as compared to outside the bladder and permits seawater to enter and refill the bladder. The bladder may have any of several forms including that of a bellows. The present invention discusses several ways by which the bladder may be compressed and several ways by which it can sense and respond to underwater wave surges.

CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from Provisional Patent Application Ser. No. 61/396,091 filed May 22, 2010. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     Efforts for finding green energy have increased for many contemporary reasons. To this end, offshore energy has been explored and has become very developed, yet, inshore wave energy has not been a topic of much exploration. Inshore waves are energetic and offer more kinetic energy than offshore energy. The energetic inshore waves also offer more challenges and efforts on the part of inventors and developers, such as access to the shore and inshore environment, conservation concerns, pollution, fouling, and spoliation of the equipment, as well as the shore and inshore environment, and creating articles that can withstand a hostile and changing environment. 
     2. Description of the Prior Art 
     Historic attempts, as well as the best current attempts, have focused on various mechanical ways of converting wave energy to bring water ashore and into a holding tank where it can be converted into energy with turbines. The Surf Power from Canada and the Wave Roller design from Finland both bring water ashore for processing using this idea with standard equipment. These two examples have mechanisms that involve a piston on leveraged structural elements, as in the Surf Power, or very large plates, as in the Wave Roller, that push a piston that converts the wave energy mechanically to force sea-water to the shore. 
     These systems seem to work but a major and expensive disadvantage and problem is that they are prone to failure and high maintenance because of the moving mechanical parts in the hostile and ever changing environment of the ocean. In addition to the problems with both of these and other devices caused by the mechanical aspects of the devices being under salt water, there are problems caused by sand and fouling agents which are very typical in any inshore environment. In addition, the resulting requirement of constant maintenance and repair is a significant problem. Another problem is that such devices are highly prone to breakage during epic wave events. Additionally, from an ecological and conservation point of view, a major problem with these devices is that they are very intrusive, unsightly, and interfere with sea life. Persons owning expensive ocean property, as well as persons enjoying the beach and shore, have often opposed the disruption of the ocean view and of sea life by man-made devices. The sound generated by the pistons of the prior art travel quite far under water. This has a negative effect on divers in the area, who also object to the unsightliness of such devices, and also on ocean life, because such prior art dissuades creatures from their ancient and natural habits, and also disrupts, annoys and harms such creatures with the mechanical noise and physical presence of the equipment. 
     These are some of the issues that developers take into consideration when considering inshore energy development. The nature and expense of these issues result in severely limiting the potential for these devices to be located anywhere inshore, offshore, or underwater, and the man hours and costs to keep, maintain, and replace the equipment adds to the cost to produce the electricity, as well as increasing the expense for the original equipment. 
     Contemporary energy harvesting devices for inshore environments should be durable, inexpensive, non-polluting, silent, non-intrusive, and also environmentally friendly. Moreover, it should be silent so as not to interfere with the above water and underwater environments. It should have as few moving parts as possible. The requirement that it be durable means it should be made of a material which is slow to degrade and when it does degrade, the material will not negatively impact the environment. It further should have minimal impact on the local underwater environment and preferably mimic local sea life. 
     Based on the foregoing, it is believed that none of the aforementioned prior art describe a wave energy collector which meets all of the stated requirements and resolves all of the above stated problems and disadvantages. Therefore, there appears to still be a need for a wave energy collector which meets all of the indicated objectives and resolves all of the indicated problems and disadvantages in a commercially viable product which can be readily manufactured, marketed, implemented, maintained and monitored at a reasonable price. 
     SUMMARY OF THE INVENTION 
     The present invention provides a unique method to translate wave energy by capturing ocean water and sending it to shore to be used for hydrodynamic energy conversion or desalination. While harvesting ocean waves is not a new topic, the approach presented here is new, very different, and far more useful from what has been proposed in the past. 
     The present invention involves a unique, biomorphic design that is absent from the industry and all prior art. The present invention is submerged, and using a bladder, in a generally bellow-like form, and an underwater vacuum-like property, the present invention utilizes the underwater wave energy to contract and expand the bladder to, respectively, force seawater to shore through a pipeline and/or hose and refill with seawater for the next cycle. One way flapper valves of preferably silicone or similar material trap the water in this bellow-like form and with compression caused by a wave, water is forced out an open pipe or hose that goes to shore. The present invention may be attached to a conduit or any other means to bring the water ashore, such as an artificial reef or Applicant&#39;s shoreline erosion mitigation device. The present invention provides water to shore 24 hours a day, seven days a week, and in all wave conditions. Five embodiments of the present invention biomorphic wave collectors are described herein, each having the same concept and function, yet having different aesthetics and suitability for active or mild wave environments. 
     The five embodiments of water collectors driven by wave energy are discovered and described herein. Other embodiments utilizing the concepts and teachings herein are within the spirit and scope of the present invention. All five of the embodiments discussed herein employ at least one one-way water intake valve, a fish screen, a deformable bladder to collect water, a means by which the device catches the wave energy, a means by which the bladder is compressed, and an egress for the extrusion of water from the device to shore. The emptied bladder will refill due to the imbalance of the water pressure inside the emptied bladder as compared to the water pressure outside the bladder. They may also have a flotation means at the end away from the water egress to facilitate the device&#39;s ability to catch the energy of a wave and also to give the device an orientation. There may also be some means to attach the present invention to a conduit or pipe and the like to facilitate the transfer of water to shore. After the sea water is extruded, the water is piped ashore where it can be used for any number of purposes, including generating hydroelectric energy. The water can be used or desalinated or returned to the ocean. 
     High Surf Design 
     Preferred embodiments for an environment with very active and high surf should preferably have a lower profile relative to the entire body, and be a generally horizontal weighted hinged collector having a flexible bladder between two plates in parallel for medium and heavy wave events and is attached to at least one, if not more, conduits that go to shore. The device should be aligned and attached such that the faces of the plates are parallel to the shore. Each plate has its own independent hinge elements, yet the two plates are connected to each other such that each can push/pull on the other. When wave forces push against the ocean-facing plate, the ocean-facing plate in turn pushes against the shore-facing plate. This results in decreasing the physical space between the two parallel plates. When the two plates lean towards each other, in one direction or the other, such action results in squeezing the bladder that resides between the two plates, thereby squeezing the water out of the bladder through an open hose or hoses of the bottom of the collector. The water will be forced out and to the shore. A flotation means on the collector will bring the parallel plates upward again, thus expanding the bladder to create suction to fill the bladder with sea-water again for another cycle. Any energetic force going back out to sea will act to straighten the form. This action will create suction to force water back into the collector through the one-way valve to refill the bladder. If no wave force is acting on the collector, the flotation means designed in the collector encourages water to be sucked back in the bladder even without wave energy. The flotation means provides this straightening affect if insufficient current is present. In epic events, the present invention will continue to move back and forth and so all aspects of the present invention are designed to withstand the forces. Any movement will translate into the result of water being sucked into the collector and forced out. In small waves, the present invention is designed to intermittently grab and send water but to a lesser degree. 
     There are several materials that can be used for the present invention that meet the previously stated requirements. By way of example, the plates of the present invention may be constructed of aircraft aluminum or stainless steel. Also, there are many flexible materials from which the bladder may be made. The flotation means should be constructed of material that can bring the plates aggressively back to the start position, perpendicular to the plain of the pipes to which the present invention is attached. While the present invention may be of any size necessary to fulfill its function, the wave energy collectors of an embodiment for an active wave environment are preferably six to twelve feet wide and four to eight feet tall. The plumbing can be in several hoses. Multiple replaceable one-way flapper valves are located on one or both plates that will allow water to enter easily and quickly and stop flow when pressure on the inside of the bladder is higher than the outside pressure. The one way valves, as well as the bladder, should be durable, and also be easily replaceable. 
     Low Surf Design 
     The embodiments of the present invention for a mild or low surf environment is preferably a more vertical design that is attached on one location to one conduit. While the embodiment may take on any form necessary to complete its function, the preferred embodiment is four to twelve feet tall and twenty-four to thirty-six inches wide. It may be made from a molded form and the preferred embodiment has the general appearance of a frond from a sea water plant. The top of the frond has a “bulb” and “petals” or “leaves” and the “stem” portion of the frond contains the bladder. The flotation means may be in the bulb, the petals or leaves, or both. The bulb also houses at least a one-way valve. Similar to the previously discussed embodiment, when there is little or no current, the flotation means will bring the wave energy collector upward. When there is wave movement, this embodiment is forced to bend to one side. As this embodiment is forced to one side, it will bend and this bending decreases the inner volume of the bladder. The water will be forced out the open hose that goes out the bottom of the wave energy collector and to the shore. The absence of force will create suction with even a slight difference of water pressure inside the collector compared to outside the collector, thus allowing the water to refill the bladder for the next cycle. Additionally, springs, stiffeners, or an outside post may be included to facilitate the compression of the bladder of this embodiment. 
     When a directional wave force is applied to this embodiment, the frond naturally will flex downwardly, starting at the top of the frond and continue in a methodical way downward towards the stiffer part of the wave energy collector. The wider profile at the top will orient perpendicular to the wave force. Multiple wave energy collectors will be fixed on the conduits and will bend in the direction of the waves, towards the beach. The fully flexed wave energy collector will exert force on the bladder, thereby forcing the water out of the open pipe at the bottom of the collector. Any energetic force going back out to sea will act to straighten the frond and assist with the flotation means to encourage water to be sucked back in the wave energy collector again. The flotation means will provide this straightening affect even if little or no current is present. When there are only small waves or gently rocking waves, water will be ejected from the frond embodiment of the present invention with small, even pulses. During epic wave events, the frond embodiment of the present invention will stop extruding water because the frond embodiment remains bent over in the big waves, without the opportunity to straighten up, decompress the bladder and take in more water. However, this embodiment must be durable and hardy enough to withstand such huge forces. 
     Various additions and modifications may be made to this embodiment. Ribs can be added or spring stainless steel to add more stiffness and strength. The entire wave energy collector also can be made of an accordion like form to increase flexibility, each step will have a living hinge. The final design must accommodate a controlled flex. Like a fishing pole, the present invention must bend and flex, not crimp and not break. The shape and size of floatation means at or near the top of the collector also has functions to cause resistance against the directed wave energy. The bulb shaped top of the frond embodiment, as illustrated is preferred because it provides both more flotation and more wave resistance. One or more one-way flapper valves allow water to enter easily and quickly and stop flow under pressure and must be designed to last or be easily replaced. 
     This embodiment of the present invention wave energy collector may also rotate about its bottom attachment point to orient to any swell direction or if in an accordion shape move easily in any direction. 
     These are but two of the multiple embodiments presented herein. Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     Referring now to  FIGS. 1 and 2 , there is shown the first embodiment, which is named the Hydroid design, of the present invention biomorphic wave energy collector. The Hydroid  100  has bladder  110 , in a bellow-like shape, residing in a tubular housing  112 . The bladder  110  of the Hydroid  100  has pleats  111  that allow the bladder to easily compress and expand. The bladder  110  shown in  FIG. 1  illustrates the bladder  110  fully expanded. The top  116  contains a one-way valve  118 . The bladder  110  is attached to the housing  112  at the top  116  of the housing  112  at the point where the one-way valve  118  resides, which allows sea water to enter the bladder  110 . The bladder  110  also has an outlet  128 , which leads toward shore and is preferably a hose-like device. 
     The housing  112  has a flexible bottom  114  which can attach to a conduit and which must be strong enough to withstand tidal and wave forces. Passing through the bottom  114  of the housing  112 , is an outlet  128  that runs from the bladder  110  through the bottom  114  of the housing  112  through a pipe or conduit and on to shore. Additionally, a grip  134  may be added to the exterior of the housing  112  so as to facilitate divers who are servicing the Hydroid  100 . 
     A wave collector  120  floats above the housing  112  of the Hydroid  100 . The wave collector  120  preferably has a floatation means  132  that may be incorporated anywhere on, in or beside the wave collector  120 . The wave collector  120  is attached to at least one strut  124  by a first attachment means  123 . At the other end of the strut  124  is a second attachment means  122 . The second attachment means  122  attaches the strut  124  to a pressure plate  121 . At several locations along the housing  112  are slots  130  cut through the body of the housing  112 , and the struts  124  may travel up and down along the open areas of their respective slots  130 . Within the housing  112 , the pressure plate  121  surrounds a lower portion of the bladder  110 . 
     When the wave collector  120  experiences the underwater surge of a wave, the wave collector  120  is tugged by that directional force and the wave collector  120  moves upwards or away from the housing  112  of the Hydroid  100 . The flotation means  132  exerts its own upward force, which must be overcome by the wave surge. The pulling on the wave collector  120  by the directional force of a wave surge results in the transfer of force to all items that are attached to the wave collector  120 , meaning, the struts  124  following the movement of the wave collector  120  move upwardly along their respective slots  130  which in turn pull the pressure plate  121  upwardly as well. The upward movement of the pressure plate  121  results in a decrease in volume of the bladder  110 , which folds along its pleats  111 , and the sea water contained in the expanded bladder  110  has nowhere to go but through outlet  128 . When the surge has passed, the flotation means  132  brings the Hydroid  100  to a relatively upright position, the one-way valve  118  allows water to enter the bladder  110 , the bladder  110  expands as it is refilled thereby lowering the pressure plate  121 , which further assists in bringing the wave collector  120  to a position hovering over the top  116  of the housing  112 . 
     Referring now to  FIGS. 3 through 10 , there is shown a second embodiment of the present invention, designated the Frond  200 , illustrating one full cycle of the Frond  200  beginning with full expansion, as illustrated in  FIGS. 3 and 4 , and ending with full compression, as illustrated in  FIGS. 7 and 8 . 
     The Frond  200  has a bulbous top  245  with a neck  266 . Inside the bulbous top  254  is at least one one-way intake valve  242  covered by a fish screen  244 . The bulbous top may have petals  246 , as shown in  FIG. 3 , or may not, as shown in  FIGS. 5 ,  7  and  9 . A flotation means may reside in the bulbous top  245 , the petals  246 , the neck  266 , or any combination thereof. A deformable, oval-shaped bladder  250  extends the length from the neck  266  to an attachment means  251 , where the Frond  200  is removeably attached, preferably to a conduit or pipe. Extending from the base of the deformable bladder  250 , beyond the attachment means  251  is an outlet  256 , which preferably runs the length of the above mentioned conduit or pipe to bring the sea water to shore. 
     The bladder  250  has texture  234  to provide a grip for divers who are servicing the Frond  200 . Along the faces of the oval-shaped bladder are ribs  260 , which, although flexible, are stiff and provide a certain amount of rigidity and resistance to the bladder  250  bending. 
     In  FIGS. 3 and 4 , the Frond  200  is shown at the beginning of a cycle, unaffected by an underwater surge. The flotation means located in the top  245 , the petals  246 , the neck  266  or any combination thereof, has brought the Frond  200  to a vertical position. The bladder  250  is preferably at maximum volume and completely filled with sea water. 
       FIGS. 5 and 6  illustrate the Frond  200  beginning to experience the onset of an underwater surge. The top  245  and neck  266  begin to bend in the direction of the force of the surge. This bending causes the upper part of the bladder  250  to flatten and compress, and, as will be shown, the bladder  250  will continue to compress from the top downward against the ribs  260 , thereby squeezing the sea water out of the bladder  250  from the top downward and out through the outlet  256 .  FIGS. 7 and 8  illustrate the Frond  200  at nearly full compression. It can be seen that the ribs  260  provide a stiffness and resistance against which the deformable bladder  250  is pressed and which facilitate the compression of the bladder  250 . It can be seen that the ribs  260  can be made of several or varying materials to provide lesser and greater resistance along the length of the bladder  250 .  FIGS. 9 and 10  illustrate the Frond  200  at complete bladder  250  compression and completely bowed over by the surge of water. All seawater within the bladder  250  has been forced out through the outlet  256  and sent to shore. 
     At the end of the surge, the Frond  200  is buoyed vertically by both the flotation means located in the top  245 , the petals  246 , the neck  266  or any combination thereof, and by the refilling of the bladder  250  through the one-way intake valve  242  due to the differential in water pressure inside and outside the bladder  250 , and the Frond is again in the position shown in  FIGS. 3 and 4 . Thus it can be seen that the Frond is particularly effective in mild surf environments and is able to respond to gentle surges in underwater current and can send pulses of pressurized water to shore continuously. The ability of the attachment means  251  to swivel like a weather vane will further maximize the efficacy of the Frond  200 . It can be seen that the Frond  200  very closely mimics the appearance and movement of sea plants. 
     Referring now to  FIGS. 11 ,  12  and  13 , there is shown a third embodiment of the present invention, designated the Tivela  300 . The Tivela  300  has two face plates  302 , each of which have a base form  382  which is preferably of a rigid or stiff material and preferably has a curvilinear profile. The curvilinear profile is preferred because it is reminiscent of the shapes of sea life and sea creatures and will have less negative impact of the visual environment. Preferably on the exterior each face plate  302 , on the base form  387 , is a flotation means  384  and along the upper perimeter of each face plate  302  is an extra quantity of flotation means  304  such that it forms a rim  385  protruding on the exterior of each face plate  302 . Along the bottom of each face plate  302  is at least one attachment means that allows swaying movement of the face plates  302 , which is illustrated in  FIGS. 11 through 13  as having a plurality of independent hinges  386  each attached to a corresponding base  387  for stability, and which are releasably attached for ease of repair and maintenance of the Tivela  300 . 
     The Tivela  300  has two face plates  302  oppositely positioned and spaced apart, such that the flotation means  384  on each face plate  302  is facing outwardly and the sides of the face plates  302  having only the base form  382  are facing each other. Enclosing the Tivela  300  along the perimeters of each of the face plates  302  is a structural wall  392  preferably made of deformable material. The structural wall  392  fully seals the interior of the Tivela  300 , thereby forming a bladder  390 . At the bottom of the Tivela  300  and through the structural wall  392  is an outlet  306 , which is shown in the figures as a hose or tube-like device that can enter a conduit or pipe  600  to carry extruded sea water ashore. Located about each face plate  302  is at least one one-way valve  304  to allow the intake of sea water into the Tivela  300 . 
     The Tivela  300  is submerged and oriented such that the face plates  302  are generally parallel to shore. In this manner, the Tivela  300  may receive the maximum directional force from underwater wave surges. The starting position of the cycle for the Tivela  300  is shown in  FIG. 12 , in a generally upright position, with each face plate  302  parallel to each other, the bladder  390  is at its maximum volume and is filled with sea water. When the Tivela  300  experiences the underwater surge of a wave, the face plate  302  facing the surge is pushed towards the shore and the shore facing face plate  302  is also pushed towards shore, as shown in  FIG. 13 . The flotation means  384  and the flotation rim  385  exerts their own upward force, which must be overcome by the wave surge. The tandem, swaying movement of the face plates  302  results in a decrease in volume of the bladder  390 , and the sea water contained in the formerly expanded bladder  390  has nowhere to go but through outlet  306 . When the surge has passed, the flotation means  384  and the flotation rim  385  brings the Tivela  300  to a relatively upright position. Due to the differential in pressure between the open ocean and the emptied bladder  390 , the at least one-way valve  304  allows water to enter and refill the bladder  390 . Thus, pulses of pressurized sea water course through the outlet  306 . The outlet  306  is preferably long enough to carry the water ashore for various purposes. 
     Referring now to  FIG. 14 , there is shown a fourth embodiment of the present invention, designated the Turbo Hydra  400 . The Turbo Hydra  400  is similar, physically and functionally, to the Hydroid  100 , but has a double bellows system and a corresponding support structure. 
     The Turbo Hydra  400  has two bellow-shaped bladders, a first bellow  418  and a second bellow  420 , which each have pleats  419 ,  421  respectively. A water permeable wall  416  separates first bellow  418  from second bellow  420 . Both first bellows  418  and second bellows  420  have their own outlet  428 . At the distal end of each of the two bellows  418 ,  420 , is an endplate  430 . At least one one-way intake valve  438  resides on each endplate  430 . Connecting each endplate  430  to the wall  416  are a combination of support struts  431  and hinges  432 , which work to fold and unfold, thereby facilitating the movement and function of the Turbo Hydra  400 . Attached to each endplate  430  and not blocking or inhibiting the flow of sea water into the intake valves  438 , is a wave collector  422 ,  423 . 
     The Turbo Hydra  400  requires a sturdy support device, which is illustrated as a foreshortened tunnel or pipe  410  having a bottom support  414  of some kind. This may be part of an artificial reef. The pipe  410  has two openings  412 ,  413  one at each end and the Turbo Hydra  400  is releasably attached to the pipe  410  by the wall  416 , preferably at both ends of wall  416 , and transversely to the pipe  410 , such that the wave collectors  422 ,  423  are oriented in the direction of the openings  410  of the pipe  410 . It can be seen that the wall  416  does not move and that the elements of the Turbo Hydra  400  that are on either side of wall  416  are the only elements that move. The pipe  410  is oriented such that the openings  412 ,  413  are parallel to shore, and, correspondingly, each wave collector  422 ,  423  is parallel to the shore. 
     The entire device, Turbo Hydra  400  and its pipe  410 , are completely submerged. As waves roll to shore, the underwater surge will enter the pipe  410  at opening  412 . When the wave collector  422  experiences the underwater surge of a wave, the wave collector  422  is pushed by that directional force and the wave collector  422  moves towards wall  416  because hinges  432  allow the struts  431  to move and second bellows  420  compresses along its pleats  421 . The volume of second bellows  420  decreases and the sea water contained therein is pushed through the outlet  428  and on to shore. Correspondingly, as the surge passes through wall  416 , the surge pushes on wave collector  423 , the struts  431  on that side of wall  416  flatten at the hinges  432  and first bellows  418  is extended to increase its volume and the differential in pressure between inside and outside first bellows  418  causes its intake valve  438  to allow sea water to enter and fill first bellows  418 . This is the condition illustrated in  FIG. 14 . 
     Correspondingly, when the surge of sea water from shore out to sea occurs, the surge enters the pipe  410  at opening  413 , wave collector  423  experiences the underwater surge of a wave, the wave collector  423  is pushed by that directional force towards wall  416  because hinges  432  allow the struts  431  on that side of wall  416  to move and first bellows  418  compresses along its pleats  419 . The volume of first bellows  418  decreases and the sea water contained therein is pushed through its corresponding outlet, not shown, and on to shore. As the surge passes through wall  416 , the surge pushes on wave collector  422 , the struts  431  on that side of wall  416  flatten at the hinges  432  and second bellows  420  is extended to increase its volume and the differential in pressure between inside and outside second bellows  420  causes its intake valve  438  to allow sea water to enter and fill second bellows  420 . 
     Referring now to  FIG. 15  there is shown a fifth embodiment of the present invention, designated the Sea Fan  500 . The Sea Fan  500  has a generally six-sided, rectangular housing  520 , of which four of the sides  521 ,  522 ,  523 ,  524  are generally rigid and two sides  525 ,  526  are deformable. All six sides  521 ,  522 ,  523 ,  524 ,  525 ,  526  are flexibly connected to each other and create a sealed interior bladder  540 . Side  521  and side  522  are positioned opposite each other; side  523  and side  524  are positioned opposite each other; and side  525  and side  526  are positioned opposite each other. Each opposing pair of sides have identical dimensions, such that side  521  and side  522  have the same length and width, side  523  and side  524  have the same length and width, and side  525  and side  526  have the same length and width. The housing  520  is preferably oriented such that the two rigid sides  521 ,  522  having the smaller surface area are the top and bottom of the housing  520 , and the two rigid sides  523  and  524  having the larger surface area are the sides perpendicular to the wave surge. Each pair of sides are generally parallel to each other and because each pair of sides have the same dimensions and because the sides are flexibly connected to each other, the housing  520  may move to and fro, yet each pair of rigid sides  521  and  522 ,  523  and  524  still remain generally parallel to other. 
     On the housing  520 , there is at least one one-way intake valve  530 . The interior of the housing  520 , as defined by the four rigid sides  521 ,  522 ,  523 ,  524  rigid and the two deformable sides  525 ,  526 , act as the bladder  540  for this embodiment. The bottom side  522  is releasably attached to a conduit or pipe  600 , by means of an attachment means  534  which also may serve as an outlet  535 . A hose  536  is attached to the other side of the attachment means  534  which lies within the pipe  600  and is of sufficient length to reach the shore and beyond, as required. 
     Residing on the top side  521  of the housing  520  is a wave collector  550 . The wave collector  550  is shown as having a generally circular shape, but may be of any shape necessary to fulfill its function. The wave collector  550  is preferably double-sided, with a circumferential wall  551  and a central surface  552 , which may be flat, as shown, or curved, which is located midway along the circumferential wall  551  such that the wave collector  550  preferably works equally in either direction. 
     The Sea Fan  500  is submerged and oriented so that the wave collector  550  is generally parallel to shore and incoming waves. When the wave collector  550  experiences the underwater surge of a wave, the wave collector  550  is pushed by that directional force and the wave collector  550  moves laterally and downwardly, as does the housing  520  of the Sea Fan, with side  522  remaining stationary, side  521  moving laterally and downwardly and parallel to side  522 , sides  523  and  524  swayed to one side, yet remaining parallel to each other, and sides  525  and  526  deforming and shrinking in area. The flotation means  553  exerts its own upward force, which must be overcome by the wave surge. The tandem, parallel movement of the three pairs of sides results in a decrease in volume of the bladder  540  and the sea water in the bladder  540  is forced out of the bladder  540  through outlet  535 . When the surge has passed, the flotation means  553  brings the Sea Fan  500  to a relatively upright position, the bladder  540  is again at maximum volume and the differential in pressure inside and outside the bladder  540  causes the one-way intake valve  530  to allow water to enter the bladder  540 , and thus the Sea Fan  500  is ready to start the cycle when the next wave surge occurs.
