This example is of the Seawater Greenhouse designed by Charlie Paton. It aims to create ideal growing conditions for hot-arid climates. In asia this includes China, The Galapagos and other Pacific Islands, India, Pakistan, Turkey, Sri-Lanka.
Seawater is evaporated at the front of the greenhouse to create cool humid conditions inside.
The air going into the greenhouse is first cooled and humidified by seawater, which trickles over the first evaporator. This provides good climate conditions for the crops. The cool and humid conditions in the greenhouse enable crops to grow with very little water. When crops are not stressed by excessive transpiration, both the yield and the quality are higher.
