Abstract

<P>PROBLEM TO BE SOLVED: To converge light using a concave mirror in order to effectively utilize sunlight and solar cells. <P>SOLUTION: The cooling of the solar cell, and the production of water or hot water using a reverse osmosis membrane if the water is seawater, and using a permeable membrane and an evaporation method if the water is polluted water, are performed concurrently at the time of power generation, in such a way that: a horizontally long cylinder is placed at a light focusing place of a concaved mirror having the same horizontal length of that of the cylinder; the solar cell is attached to the light receiving surface; and making seawater, polluted water and fresh water flow in the cylinder. Furthermore in a coastal desert area, hydrogen and oxygen can be produced by electrolyzing seawater by utilizing the generated electricity. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

太陽電池を有効利用するために、凹面鏡を使って光を集束する。In order to make effective use of solar cells, a concave mirror is used to focus the light.

技術背景Technical background

太陽電池で大規模な発電をするためには、太陽電池の価格が高すぎる。The price of solar cells is too high for large-scale power generation using solar cells.

発明が解決しようとする課題Problems to be solved by the invention

現在、太陽電池を安価に獲得するための研究が日夜行なわれており、色素増感形太陽電池はシリコン形の１／１０の価格で製造可能となりそうである。しかし、太陽光による性能劣化と発電効率の問題が解決されていない。
即ち、太陽光発電を大規模化する段階に入っていない。Currently, research for obtaining solar cells at low cost is being conducted day and night, and it is likely that dye-sensitized solar cells can be manufactured at a price 1/10 that of silicon type. However, the problem of performance degradation and power generation efficiency due to sunlight has not been solved.
That is, it has not entered the stage of increasing the scale of photovoltaic power generation.

課題を解決するための手段Means for solving the problem

太陽電池の単価を下げて、発電原価を下げるのではなく、太陽電池の利用法を変えて、発電原価を下げよう、と考えた。
具体的に、凹面鏡の原理を利用して、横長の凹面鏡の光の集束部分に、同じく横長の筒を設置して、その反射光の受光面に太陽電池を取り付けて発電し、筒の中には、海水、汚水、淡水などを流して、太陽電池の冷却と温水の製造を行う。
この温水は、海水ならば逆侵透膜を使って淡水を造水する際の効率を良くし、又、蒸発法で淡水を造水するのに、使える。
又、汚水の場合も、透過膜と蒸発法で同じ様に淡水造水ができる。
そして、この際の太陽電池の利用率を概算してみると、
例えば、タテ２．５ｍ、ヨコ５ｍの太陽電池パネルを考えた場合、
２．５×５＝１２．５ｍ２
この太陽電池パネル全体が凹面鏡となりその光の集束場所の太陽電池が（筒に張る）
タテ１０ｃｍ、ヨコ５ｍとすると、
０．１×５＝０．５ｍ２
即ち、１２．５ｍ２÷０．５ｍ２＝２５
となり、太陽電池の利用率は２５倍となる。
これは太陽電池の値段が１／２５になることを意味する。
現実には、凹面鏡を作らねばならないが、単純化して判りやすく、
太陽電池（パネル）１ｍ２−１００Ｗ−６０，０００．円とすると、０．５ｍ２−３０，０００．円
即ち、３０，０００円の太陽電池で１．２５ｋｗ／Ｈの発電を行うことになる。Instead of lowering the unit price of solar cells to lower the cost of power generation, we decided to change the usage of solar cells to lower the cost of power generation.
Specifically, using the principle of the concave mirror, a horizontally long tube is installed in the light converging part of the horizontally long concave mirror, and a solar cell is attached to the light receiving surface of the reflected light to generate power. Uses solar water, sewage, fresh water, etc. to cool solar cells and produce hot water.
If the seawater is seawater, it can be used to improve the efficiency when freshwater is produced using a reverse osmosis membrane, and can be used to produce freshwater by evaporation.
In the case of sewage, fresh water can be produced in the same manner by the permeable membrane and evaporation method.
And if you approximate the utilization rate of solar cells at this time,
For example, when considering a solar panel with a length of 2.5 m and a width of 5 m,
2.5 × 5 = 12.5m 2
The whole solar cell panel becomes a concave mirror, and the solar cell at the focal point of the light is stretched on a tube.
If the length is 10cm and the width is 5m,
0.1 × 5 = 0.5m 2
That is, 12.5 m 2 ÷ 0.5 m 2 = 25
Thus, the utilization rate of solar cells is 25 times.
This means that the price of the solar cell will be 1/25.
In reality, you have to make a concave mirror, but it is simple and easy to understand,
Solar cell (panel) 1m 2 -100W-60,000. Assuming a circle, 0.5 m 2 -30,000. That is, 1.25 kW / H of power is generated by a solar cell of 30,000 yen.

海岸砂漠で、この横長の太陽電池付の凹面鏡を大量に設置して発電し、この発電気で海水を電気分解し、この発生水素と酸素の圧力で逆侵透膜に海水を供給して淡水を製造し、且つ、温水を利用して、やはり淡水を造水する。
即ち、水素資源と水の両方を獲得することが出来る。In the coastal desert, a large number of concave mirrors with horizontally long solar cells are installed to generate electricity, and the seawater is electrolyzed with this electricity, and the seawater is supplied to the reverse osmosis membrane with the generated hydrogen and oxygen pressure to produce fresh water. And fresh water is also produced using warm water.
That is, both hydrogen resources and water can be acquired.

発明の効果The invention's effect

人類の燃料資源、水資源の問題を解決し砂漠に農業をもたらす。Solving human fuel and water problems and bringing agriculture to the desert.
