PIN is a solar power modular machine,it can condense moisture from sea breeze by cooling module.The target of PIN is solving salinization of costal area.By condensing moisture,firstly,PIN can increase the content of freshwater of groundwater horizon; secondly, to supply the water source of the salt-tolerant plants(a kind of plants can “eat” the salt of ground). PIN can purify the salinization area and supply a new source of gathering water, then it solves the problems of erosion by sea breeze or seawater of coastal area.At last,the threat of environment can be changed by PIN to become a eco-friendly condition.
