  • This hypotenuse rests on a rigid structure formed by pillars and beams x7 made of steel and anchored to the seabed.
  • the hypotenuse y3 is strictly made of transparent material, glass/transparent plastic material or latest- generation transparent photovoltaic panels. The irradiation of the sun on the above- mentioned transparent surface creates a greenhouse effect between the plate in question and the surface of the sea.
  • the shorter cathetus - rectangular plane - that is, the one that pointing upwards creates a side of 1.65 meters - Figs 1 and 2, y2 - continues for about twice its length also under the water, forming a 30-degree angle with the water - which could even drop to a 20-degree angle - reaching under the longer cathetus and it is made of the same material - black fiberglass, thus forming a rectangular plane under the sea - Figs. 1 and 2, y4.
  • the same panel - rectangular plane - also continues upwards rising above the cathetus by 1.65 meters above the sea surface - Fig. 2, y2 - by an equal measure but with different material and with a different orientation, thus reaching a total of 3.30 meters above the water surface.
  • y5 - is a refractive mirror - Figs. 1 and 2, y5 - and can be adjusted by slightly rotating the base.
  • This refractive mirror extends over the entire length of the prism.
  • the opposite end of the hypotenuse i.e. the one that is in contact with the water to the south, is also supported by the rigid structure x6 made of steel - girders, but it closes the surface of the sea with a black fiberglass panel - Figs.
  • y4 that goes underwater to a depth of about 3 meters, and that is rotated, in its position orthogonal to the water - by 60/80 degrees towards the inside of the hypotenuse, thus forming another rectangular plane - Fig. 1, y4.
  • the aim of this artifact is to build, with the aid of electric resistors ylO - like those used for domestic water heaters - placed at the surface and at the water level, a furnace capable of reaching a temperature of over 100 degrees centigrade at its inside.
  • the supporting structure x6 of the artifact consists of pillars x7 anchored firmly to the seabed.
  • One of these steel pillars points skywards for allowing laying of a wind turbine to produce energy for water needs.
  • a tank - Fig. 2, x3 - is fixed to the base of this pillar x8 in order to collect water. Said tank is tubular.
  • the first one lets the air out from the top of the tank - Fig. 2, x2.
  • This pipe rises above the tank, immersed in the sea, up to the end of the pillar x8 supporting the wind power system.
  • the second pipe - Fig. 2, x4 - also rises from the top of the tank and goes into the volume of the right-angled triangular prism serving as a water-evaporating furnace.
  • This pipe has the purpose of conveying the vapor into the tank to turn it back into distilled water.
  • the third pipe - Fig. 2, x5 - is placed at the beginning and the end of the tank, i.e. at its both ends, and draws the water produced in the lower part of the tank for transferring the same.
  • yl - a grid is placed, formed by resistors - like those used for domestic water heaters - placed transversely, parallel to each other and joined at the two ends by two longitudinal rods which are joined to the rigid supporting structure x6 so as to hold the water resistors ylO at the water level, said resistors being apt to be heated to high temperatures by an arrangement of lenses.
  • Said resistors ylO heat up to over 1000 degrees centigrade and are spaced apart at a distance of 0.20/0.30 meters and are painted black.
  • the two ends of the artifact are closed by trapezoidal transparent panels - Fig. 2, y6 - said panels dropping down orthogonally from said hypotenuse by about 2 meters below the surface of the water in order to contain the air pressure inside the prism.
  • the mentioned panels - Fig. 2, y6 - are trapezoid- shaped since the natural triangular shape to close the prism has been extended with a view to immersing a further part thereof in the water.
  • This volume between the hypotenuse and the surface of the water - prism - serving as an assisted solar furnace, must be isolated and sealed in order to have the features of a large pressure cooker with pipes as the only outlet - Fig.
  • Said surface, of the body of water can also be lowered from its natural level by virtue of the principle of the upturned glass immersed in a liquid which does not allow water to enter inside due to the presence of a volume of air and the level of said water/air is adjusted by the allowed pressure.
  • Said three-dimensional structure has no pumping systems for carrying the water to be treated, because the liquid autonomously enters the open space in its lower portion.
  • the project in question is based on the principles of solar furnaces that have always been used to produce thermal energy mostly for the preparation of food. With the present invention, the aim is to combine wind energy or other sources of energy with the heat produced by solar furnaces, so as to obtain the heat necessary to produce purified water.
  • the resistors ylO are placed parallel to each other at intervals of about 0.20 /0.30 meters and joined at the ends with an orthogonal rod emerging from water and adapted to be heated to high temperatures by means of lenses - Fig. 2, y7.
  • an iron float is provided at the center of each resistor, which float keeps the resistors immersed in water a couple of centimeters below the surface.
  • These resistors ylO maintain the first centimeter of water below the surface at a temperature between 90 and 100 degrees centigrade.
  • the task of the resistors ylO is to increase the temperature of the seawater from about 20 degrees centigrade to the above-mentioned temperature.
  • the tank has another pipe x2 that rises from the top portion orthogonally out of the sea up to a hundred meters in height to seek cooler air that will help to create intake currents for the gaseous water coming from the intake vents placed in the solar furnace.
  • the temperature of the same drops suddenly from about 110 degrees to about 25 degrees centigrade. This sudden change between these two temperatures transforms the water vapor inside the said tank into purified liquid water once again.
  • the energy consumption has decreased by about 20%.
  • the resistors ylO arranged at the water level (immediately below the surface of the liquid) are joined together, both north and south, by a profile - Fig. 2, y9 - of the same color and material, said profile being formed in the approximate shape of a very open V defining therein and angle between 90 and 120 degrees.
  • Said profile has a leg positioned in such a way as to join the resistors ylO to one another by running transversely through the structure and remaining at the same level as the liquid, but a couple of centimeters higher.
  • the other leg rests on the black panel closing the solar furnace.
  • This profile is apt to be heated up to high temperatures, 2000 degrees centigrade, by means of small, but very powerful, lenses - Fig. 2, y7 - which with their focal point concentrate the sun rays onto the mentioned V-shaped profile.

Abstract

L'artefact est un prisme dans lequel un plan est formé par la couche de surface de l'eau de mer - généralement de l'eau de mer - et le plan dudit prisme est donc une partie de la mer/de l'eau. Un second plan, plus petit que celui mentionné ci-dessus, est orthogonal au plan d'eau et est, par exemple, constitué d'un matériau tel que de la fibre de verre colorée noire. Un troisième plan relie les plans ci-dessus avec une inclinaison de préférence d'environ 25% à partir des bords libres, strictement en matériau transparent, par exemple en verre. Les deux plans triangulaires des côtés sont également fermés hermétiquement par des panneaux trapézoïdaux, à mesure qu'ils pénètrent dans l'eau, et sont également constitués d'un matériau transparent. Le plan d'eau présente, au niveau de ses deux extrémités libres, un plan pour chaque partie qui présente un angle de préférence d'environ 30 degrés par rapport aux têtes dans l'eau vers le centre du prisme. L'ensemble des exemples ci-dessus est mieux représenté dans la description et dans les dessins annexés. Le plan élevé du prisme est orienté vers l'intérieur de manière à former un four solaire à l'intérieur. Le plan sur l'eau est équipé d'une grille de résistances électriques comme celles pour des chauffe-eau domestiques-sur toute sa surface. L'énergie électrique nécessaire peut être produite par des éoliennes, des panneaux photovoltaïques, des systèmes de production d'énergie à base de combustible fossile ou à base d'hydrogène, ou d'autres types de systèmes de génération d'énergie. Le but du système est de produire de l'eau potable pure à partir de la vapeur d'eau qui est générée dans le four solaire du prisme.
