    Method and system of electric power generation in a boat. The present invention relates to a method and system for generating electric power in a ship comprising: a duct (10), practiced in the hull of the ship below its waterline, to receive, as a result of the advance of the ship, a flow of incoming water and expelling said flow through an outlet (3); closure means, coupled to the conduit entrance, to adopt an open position or a closed position; a hydraulic turbine (11) inside the duct, to be moved by the incoming water flow; and an electric generator (9) connected to the hydraulic turbine, to generate electric power from the movement transmitted by the turbine.

    a generator installed inside and converts mechanical energy into electrical energy. In this way, the energy of the water is used by the hydraulic turbine, activated by the mass of water that passes through it, and is used to produce electrical energy by connecting the turbine shaft with an electric generator (alternator), which transforms the
    5 mechanical energy in electrical energy.
    The electrical power that can be obtained depends on the amount of water channeled to the turbine, the pressure and the electrical efficiency of the generator. The water that leaves the turbine is returned to the sea once it has crossed the nozzle without suffering any alteration.
    10 Said electric power feeds an electric motor or a hybrid motor, used to move the boat or it can be stored in batteries for later use.
    The hull of the ship is modified for the installation of the duct, which is preferably
    15 it chooses with a nozzle shape, but any other type of conduit with a favorable geometry can be used to channel the water, and the rest of the elements necessary for the generation of electrical energy, mainly the electric generators, so that it is previously necessary to perform necessary calculations of resistance to the advance, cavitation, sizing and in general, calculations of behavior in the sea in different
    20 ship speed regimes.
    Actually, the exterior design of the ship's hull, pressure gradients and the efficient ways in the resistance to the advance, are not modified at all, but the present invention, totally respecting the geometry of the hull whenever possible, proposes
    25 a construction of the type of ships with moving bow.
    The modifications in the design of the hull, according to the present invention, integrate the physics and mechanics of fluids already tested in the hydraulic power plants. The concrete design and its adaptation to the different types of ships, responds to a multitude of variables that influence
    30 in performance, such as the different speeds of approach and distance to coast or port, in calm waters, waves, headwaters, consumptions, flows, angles of attack, angles of entry and exit, drafts, continuity of flow or seats . In any case, the present invention contemplates type parameters that facilitate its adaptation to most ships.

    The geometry of the nozzle can adopt different curvatures, depending on the effect and the performance sought, but according to another embodiment of the invention, the nozzle can follow a completely straight design from the entrance to the bottom of the ship, with the length, tilt and dimensions most appropriate for each vessel.
    Of course, in case the gates are closed at the entrance of the duct, either in the form of a nozzle or in any other way chosen, the hydrodynamics of the vessel remains intact and, since it does not allow the entry of water, there is no effect of braking. It must be taken into account that both the entrances and the exits have a sealed closure in navigation that allows to determine the opening and closing of said gates or hatches of the ducts when the conditions are favorable or not for the maximum working performance of the system.
    The generator that connects to each of the hydraulic turbines is represented in Figure 7 occupying an additional space and connected at a certain distance from the turbine, but according to an alternative embodiment of the present invention, the generator consists of an electric generator integrated into the turbine itself, preferably around it, so that it makes better use of the available space.
    Figure 8 shows in detail a bottom view of a ship with a bulb where, according to one of the embodiments of the invention, said bulb is used precisely to provide at its bottom an outlet (12) for a nozzle.
    The entrance to the nozzle or conduit chosen can also be located, according to one of the embodiments, in the front of the bow bulb or any other area of the hull in the live work, which allows the necessary physics to activate the system. Thus, the nozzle or conduit chosen, crosses the bulb completely and evacuates the water either by the bottom or by a side as it has been seen in the previous embodiments.
    Another alternative embodiment for the system of the present invention relates to installing the inlet of the nozzle in the keel of the vessel, at the angle studied of each most favorable vessel, always complying with the construction standards of the classification societies
    Figure 9 shows one of the embodiments of the invention, where the geometry of a nozzle (13) can be seen in detail, where the direction, inclination, flow, water evacuation 11

    Ship model, its size, operational destination, structural complexity and available spaces in the hull.
    Once all the elements described above have been chosen, the
    5 possibility of modifying the final configuration through the study, either in simulation or in real conditions, of the speed of the ship with the system in operation, study of electrical production and consumption of the ship with the open hatch (s). The work capacity and optimum performance of the turbines, is directly related to a speed of navigation that allows the ship to advance with the open hatches, without costs
    10 consumption and performance too high. This is not relevant for braking situations, but nevertheless, it is relevant for eventual operation during the running order with the engines running, where the ratio between the electrical energy generated by the turbines versus the loss of speed, time and extra consumption due to advance resistance is essential to determine if it is advisable to activate the system
    15 of the present invention or not.
    Finally, it is important to consider that the implementation of the present invention in ships, could be combined with any other work of transformation or renewal of the hull, to take advantage and include it in said hull, since it does not imply changes in the design
    20 of the fairing or of some of its forms, so the difficulties of its installation would be the same as any other service equipment / system, or what is the same, it would not have more complexity than the installation of other current systems as propellants of maneuver in Proa and that, despite some initial difficulties, are already widely consolidated in most shipping companies.
