Description of the invention entitled:

"Sea wave energy production system for the generation of clean energy"

TEXT OF THE DESCRIPTION

The present invention is part of the renewable energy sector and is aimed at the use and transformation of the wave motion of the sea for the production of energy, through the treatment carried out by means of the industrial invention which is the subject of the present application. In the structuring of the invention, particular attention was paid to the possibility of using the renewable energy constituted by the wave motion of the sea. The energy produced by sea waves can be considered as a concentrated form of solar energy; in fact the solar radiation determines a distribution of the different temperatures from latitude to latitude, which cause the generation of winds. The winds in turn ripple the surface of the sea forming waves that can travel in deep water for miles without incurring noticeable energy losses. Thanks to the system in question, it is possible to use the wave motion of the sea to generate electricity to be re-introduced into the consumption grids, as is currently the case for other alternative energies (eg solar, wind). The industrial invention in question, once installed and used in the chosen area, will guarantee the production of energy from the wave motion, using an innovative and unprecedented method. The characteristic of continuity in the development of the phenomenon guarantees the continuous functionality of the system. The fundamental innovation factors of the invention are two: the raw material for generating the final energy, consisting of the waves of the sea and the method of transformation of the energy contained in the aforementioned primary source (wave motion) through the invention object of this application, according to the methods and with the advantages that are illustrated below.

1) Thanks to the particular design of the system in question, it is possible to generate energy from the wave motion of the sea without creating any environmental problems or problems to the seabed that could have a negative impact on the system itself. The exploitation system of the wave motion object of the present application, as will be explained below, is adaptable to all the geographic and morphological characteristics of the coasts, therefore its adaptability is very wide. Energy is produced with generators designed for renewable sources, therefore capable of working even at irregular speeds, as in a wind power plant. On board the platform there will be the same electrical system of a wind turbine, unlike the generator which will be smaller thanks to the possibility of obtaining more revolutions per minute (through a revolutions multiplier) from the movement of the wave motion. Thanks to the adaptability characteristics of the system as a whole, it will be possible to choose, through a design variant, whether to transform the current on the platform or transform it on land, in relation to the distance that will be from the coast. The distance from the coast will be evaluated on the geographical characteristics of the marine site of destination.

2) The structure of the invention object of the present application is modular and self-supporting and has been designed to be installed in any conformation of the seabed and adapted to any type of assembly scenario to maintain maximum efficiency.

3) The specific design of the use of the discovery will take into account the morphology of the territory, favoring a minimum distance from the coast to contain costs. The advantages of this type of floating buoy are highlighted both in the novelty of the invention and in respect for the environment: both installation and removal do not involve complex procedures, do not damage the sites and do not require special authorizations.

4) Consequently, the operation of plants of this kind will have practically no impact on the environmental and marine system, generating no dangerous impact on the environment where it is installed. Since this is an instrument to be placed at sea, the problem has arisen of evaluating the conflict with the passage of boats and marine logistics, finding the solution by means of special light indicators in accordance with the reference sector, located on the structure.
