据意大利《欧洲人》周刊1990年5月5日报道,在玛格丽塔-迪萨沃亚的盐田中,有一个特殊的盐池,这是阿吉普公司建造的一个“太阳能湖”。太阳能湖的湖面就是一个巨大的采光板,由盐水组成,但每一层盐水的盐份浓度不同。它的作用原理同温室原理相似:阳光的热量可以透过湖面进入湖内,然后被下层盐份更浓的湖水吸收,湖水即被加热。负责这一研究的扎诺尼工程师说:“在5个半月中,已使湖水的温度达到70℃。”再过几个月可以达到90℃。世界纪录是105℃,足意大利女物理学家赞格拉多创造的。玛格丽-迪萨沃亚的这个太阳能湖于今年3月底正式对外开放,面积为2.5万平方米,可发电500千瓦,使用的水是90℃的热水,相当于350吨石油的能量。同这个湖相联的是一个海水淡化装置。热水送入热交换器,然后带动海水淡化器,再把浓缩过的盐水注入湖底。这个湖一天可生产100到120升淡水。这只是阿吉普公司的一个样板,可根据客户的要求复制。这一样板的成本为30亿里拉(约合260万美 According to the Italian “Europeans” magazine reported on May 5, 1990, there is a special salt pond in the marina-di Savoia salt field, which is a “solar lake” built by Agpex. The lake of a solar lake is a huge daylight, made up of salt water, but with salt concentrations in each layer of brine. Its principle of action is similar to that of the greenhouse: the heat of the sun can enter the lake through the lake, and then be absorbed by the deeper salt of the underlying salt, which heats the lake. Zhanoni, who is in charge of the research, said: “In five and a half months, the temperature of the lake has been raised to 70 ° C.” In a few months it can reach 90 ° C. The world record is 105 ° C, created by Italian female physicist Zambrano. This solar lake in Margarita-Savoia officially opened to the public at the end of March this year. It covers an area of ​​25,000 square meters and generates 500 kilowatts of electricity. The water used is 90 ° C hot water, equivalent to 350 tons of oil. Associated with this lake is a desalination plant. Hot water is sent to the heat exchanger and the seawater desalinator is activated, then the concentrated brine is injected into the bottom of the lake. The lake produces 100 to 120 liters of fresh water a day. This is just a sample of Agap companies, according to customer requirements copy. The cost of this model is 3 billion liras (about 2.6 million U.S. dollars)
