Description

SYSTEM FOR THE GENERATION OF ELECTRICAL ENERGY ALTERNATIVE FIELD OF THE INVENTION The present invention refers to systems for the generation of electrical energy capable of generating work cycles of electric power generation, which do not depend on the use of fossil fuels or on the availability of renewable energy sources such as the sun, air or the water to mention a few.

OBJECT OF THE INVENTION The object of the present invention is to provide a system for the generation of electrical energy using sources powered by its own electromotive force, without the use of renewable energies or fossil fuels, and capable of satisfying the energy demand of different types of energy consumption as a domestic consumption, one of high consumption and a medium commercial consumption.

BACKGROUND The antecedents for systems of generation of electrical energy more well-known are the wind and solar systems, which count on a quite acceptable generation effectiveness and come to be an important support in the generation of electrical energy since at the same time they are of great help for the care of the environment by basing their work on renewable energies such as wind and sun respectively, these systems, although they are quite good, are not yet widely accepted because they depend to a large extent on the factors mentioned above and the climatic changes that could affect its operation, as well as the need for large spaces for its installation and its high costs.

Other forms of energy generation base their work on the consumption of fossil fuels and pollutants, which generate greenhouse gases and which are extremely harmful to the environment examples of these fuels are diesel, gasoline and gas among others.

The system of the present invention is an alternative electric power generation system that has the advantage that it does not consume any type of renewable energy or external factor for its operation, since it is completely self-sufficient and does not depend on external factors such as availability of the wind, the sun or some fossil fuel.

The present invention provides in one of its modalities, a system of the size of a refrigerator for domestic use, capable of satisfying the energy demand corresponding to a domestic use of high consumption and the average commercial one; the space needed for installation is very small and its presentation does not alter the environment of the place.

The company General Electric has a system that basically handles similar concepts to this generation system, only that the plant designed by General Electric can only be used for emergency and for short periods of time and it depends 100% on the accumulation of energy in your battery bank without a permanent generation system.

The patent application WO2008010734 mentions the generation of energy by means of a magnetic generator driven by an electromotive force of an electric motor, however, it uses external energy for its operation.

These systems are only for generation and storage of energy without controls that allow their automation in case of emergency and that are only systems to be used in emergency and not continuous work.
