Loading and storing energy on boats. One of the examples of loading are alternators on engine. It is very expensive solution because one hour of operation of the device consumes from 8 to 10 liters of oil. Solar panels are a very good solution but they only work during the day. They produce more energy when we are under a bigger cat for sunlight, that is, the closer to the equator we acquire more energy. Boats can also be charged by connecting them to the electricity, it is enough to have an exhaust generator. It gives you charging control, but unfortunately it is quite expensive because we need oil for it. Wind turbine is another solution. Wind power is needed to obtain energy from it. You can also get energy from the screw shaft. There are many different types of generators, for example, for the energy to be generated, it is necessary to flow. We store the produced energy in batteries.
