DESCRIPTION:
BRIEF SUMMARY
Subject of the invention is a device for utilizing solar energy with collecting-radiating units located on geostatics orbit as well as a procedure for precluding from and/or alleviating of atmospherical formations i.e. tropical cyclones, tornados, monsoons causing flooding and hail.
One basic advantage of the utilization of the solar energy is that it utilizes energy free of charge and at the same time the environment is not polluted. After the oil price boom during the seventies appeared the idea of establishing devices utilizing solar energy and stationing on geosynchronized orbit around the Earth. According to one envisage ribbon mirrors would be placed on geo-synchronized orbit and these focus the solar radiation to the generating electrical energy with energy transforming devices which transform the electrical current to micro wave form and radiate to Earth. This solution has been abounded because of the difficulties of the implementation.
According to an other solution solar cells with huge surfaces would be deployed on the geo-synchronized orbit and there credating electrical current generating plantation where the electrical energy is transformed into micro wave form and it is radiated to the receivers on Earth. Basic disadvantage of this solution is that the silicon solar cells are expensive and its efficiency is very low bacause of the energy transformation with more stages as well as the diffraction of micro waves.
Solar cells are used in practice for generating electrical current requeseted to the ooperation of different satellites and devices in huge quantity moving on different geostatic orbit and course around the Earth. Silicon crystals or one unit crystal made of gallium arsenide or poly crystals are used for solar cells, and the blanks made of them are coated by translucent resistant film which protect them against the impact of the powder like micro meteorites.
The solar cells introduced above have especially high level importance in providing electrical current for the satellites on geostatic orbit because these devices mainly used for program broadcasting, telecommunication (as well as for military mission) have very extended life time period. Basic condition for this long life period functioning is the continuous energy supply which is provided by solar cells.
Despite of the fact that in the part of space out side of the atmosphere solar energy is available without limitation according to time and location as coordinates and this solar energy, with the intensity of 1.3 kW/square meter, is not influenced as it is in the case of solar energy radiated to the Earth and influenced by clouds in the atmosphere and the absorbing ability of the atmosphere this beneficial energy source is utilized on a very low level (as it was introduced before) today according to the present stage of the technical development.
Starting from that recognition that the solar energy collected by large scale mirror system located on a geostatic orbit because of the concentration ability of the sunbeams can be transferred to the receptor on the Earth with concentrated beam with low level of loss and without any polluting of the environment further the accurate setting up of the mirror system mentioned above can be established using the navigation systems developed for the satellite technology and because of this these devices are used for energy generation and/or for defense against atmospheric formation causing catastrophes.
The move of mirrors with large surface made of metallic or plastic panels with proper tensile and mirrored on one side of the surface as well as film elements with mirroring surface stretched on frame made of navigation and other type of structural elements is made by hydraulic or mechanic move mechanism launched on the geostatic orbit.
Computer with high power and controlling equipment coupled with navigation equipment radiating and absorbing laser and micro wave beams set up separately and in the proper distances from the mirror groups according to the appropriate coordinates as well on the
