A seawater greenhouse is a greenhouse structure that enables the growth of crops and the production of fresh water in arid regions. Arid regions constitute about one third of the Earth's land area. Seawater greenhouse technology aims to mitigate issues such as global water scarcity, peak water and soil becoming salted.[1] The system uses seawater and solar energy, and has a similar structure to the pad-and-fan greenhouse, but with additional evaporators and condensers.[1] The seawater is pumped into the greenhouse to create a cool and humid environment, the optimal conditions for the cultivation of temperate crops.[1] The freshwater is produced in a condensed state created by the solar desalination principle, which removes salt and impurities.[2] Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants.
