   My guess is that systems capture energy from waves by floats have a low yield. Sure, Member of the ocean, where large waves and vast stretches efficiency problem is not urgent. Then you can use various forms of sensors. For large closed as if the Black sea, where average wind waves are small, put stringent devise high efficiency systems for capturing energy from waves. Such a system would consist of a hydraulic wheel (de tip bank), width greater (about the length of the crest of the wave) and of small diameter and having in front a lifting concentrator (for small waves), like a funnel that lifts the wave from the depths of the water. The lifting height of the water is small, but circulating a large volume of water would provide the necessary power to operate some tandems of diaphragm pumps that raise the water to a convenient height for continuous operation of the turbine that drives the generator in charge. Above the hydraulic wheel, with a long axis of about 5-6 m and a diameter of about 0,5-1 m, positioned horizontally, immediately above the water level, the dam is placed, with a slightly inclined plane, on which the water of the great waves is thrown, of the storm, plan (parapet) which leads water to fall into the wheel blades. In this way, the big waves are also capitalized, which although rare, they come with a lot of energy, which if not absorbed in some way, it would have a strong erosive effect on the shore. That is why such systems are cost-effective to install, where the protection of the shore from strong wave erosion is required. An energy dam, formed by the parallel alignment with the shore of many such systems, would produce a significant stream of water, in a canal suspended right on the top of the dam. Water current that would continuously supply the working turbine. Thus the dam, in addition to the role of protecting the shore from marine erosion, it would also be an energy source. I think that this is the only way that energy entrepreneurs could be interested in investing in some voluminous and expensive constructions., in which, however, the energy gain is small, because the waves from the Black Sea, on average they are low energy.

     Alta idee ar fi ca lantul de roti hidraulice cuplate intre ele, sa antreneze, prin intermediul unui multiplicator de turatie, un generator de mare putere, care ar furniza la borne o putere (energie) variabila, (proportionala) cu puterea medie a valurilor. Aceasta putere ar alimenta electrolizoare, care pot functiona si in regim variabil al energiei. Electrolizoarele produc hidrogen si oxigen, care ar putea fi folosite in uzine chimice, la prepararea combustibililor sintetici cum ar fi propanul. Aceasta ar fi o forma chimica stabila de stocare a energiei. Acest sistem ar fi mai economic deoarece elimina canalul adductor suspendat pe coronamentul digului precum si turbina de lucru.

       Another system for capturing energy from the waves would eliminate very large hydraulic wheels that are actually as many turbines and are very expensive.. Large hydraulic wheels, they would be replaced with pendulum blades, which can be more easily built to the size of the waves. blades, the size of the wave, it would swing in some alveoli with an arc profile at 90 degrees. In front of the pallets would be, under the water a rising slope of the wave and above the water a parapet, voucher manager, inclined at 45 degrees. blades, in their pendulum swing, would inject some injection pumps, which injects pressurized water into a pressure tube. In the pressure tube a pillow of compressed air at a pressure of 10-12 atmospheres is formed above the water., which would amount to a forced pipeline, with a waterfall height of 100-120 meters. Water is sent from the pressure tube into a Pelton turbine, which drives the generator in constant mode. So the pressure tube, to which all the injection pumps from the energy dam component are connected, constitutes the integrating system of the discontinuous energy of the waves.

         I think you could convey the idea of the energy dig, that works on the principle of peristaltic pump, to an institute of marine digests design. I think like such a dig, which is still a complex structure, would consume fewer building materials and even allow an industrial wave energy exploitation. Because they could work on a large length of waves. and could capture the small waves and large storm waves. I say that for a storm wave 2 m high, Wave ridge would be 1 m above the water level. Section of the section, placed immediately below the water level, would therefore be 1 m^2. On the wall from the lagoon are large section cuts, covered by water intake valves in deformable sac. The valves must thus be sized and profiled, so that they are light and resistant to water pressure and ensure the filling of the bag, with water in the lagoon, In the short time of the incident wave withdrawal. In front of the gallery through which water is inhaled, by the pressure of the waves, Into equal section, also of 1 m^2 is the deformable sac, which takes over the pressure of the incident wave and sends it to the water from the gallery. The water that is inlaid to flow through the discharge valves, located on the diaphragms between sections. Diaphragms that occupy exactly the transverse section of the gallery, through which water is inpassed, to the hydraulic wheel located at the end of the section of sections. At the end of the section of sections, linked to series, the water is raised on an inclined ramp, up to the working height of the hydraulic wheel. The hydraulic wheel must have the ability to turbulate a large volume of water. Because all the strength of the waves is contained in a large volume of water. In front of the deformable bag is a funnel located, consisting of a submarine slope for lifting the wave from the deep water and from a parapet inclined to 45 degrees, placed immediately above the water. The purpose of the funnel is to concentrate the incident wave and direct it on the deformable bag. The assembly of the funnel would add another meter to the width of the dam. So the total width of the enegetic dam would be 3 m. Above the dam can be placed on the pressurized tanks, in which water under pressure is injected. Pressure that will punch water through the jets acting on the pelton turbines, who will train the electric generator in constant regime.. And above the pressurized tanks can be placed the promenade of the dam.

           PS Large hydraulic wheel, that would receive water from a large length of waves, from two parts, coming from two strings of sections, would act some water injection pumps in the preorized tanks, Until the work pressure is reached.
