Meaning:
Water extraction from the air is a method to convert moisture in the air into drinking water.
The current situation of water resources:
72% of the Earth's surface is covered by water, but freshwater resources account for only 0.5% of all water resources, nearly 70% of freshwater is fixed in the ice of Antarctica and Greenland, and the rest is mostly soil moisture or deep groundwater, which cannot be used by human beings.
Working principle:
The use of brine hygroscopic effect of absorbing moisture in the air. The first step is to allow the brine to flow down from the top of a tower-shaped device and absorb moisture from the air in the process. The brine is then pumped into a vacuum vessel several meters high, and then solar energy is used to heat the brine, which has been diluted by the absorption of moisture and distills out the water that does not contain salt.
从空气中提取水是一种将空气中的湿气转化为饮用水的方法。
水资源的现状：
地球表面的72%被水覆盖，但淡水资源仅占所有水资源的0.5%，近70%的淡水被冰封在南极洲和格陵兰的冰中，其余大部分是土壤湿度或深层地下水，无法被人类利用。
工作原理：
利用盐水的吸湿效应吸收空气中的湿气。第一步是让盐水从塔状装置的顶部流下，并在过程中吸收空气中的湿气。然后，将盐水泵入几米高的真空容器中，再利用太阳能加热被湿气稀释的盐水，将不含盐分的水蒸馏出来。
