Soil cultivation system for desert regions - sun evaporates seawater which condenses and falls to plants

摘要

The basis of the system is a reservoir containing seawater. The sides of the reservoir are transparent and can be double walls with a cavity between them. The roof is also transparent, allowing max. penetration of sunlight. The inner walls are provided with holes, above the level of the water, through which the evaporated seawater passes into the cavity where it condenses. Below this apparatus is the bed in which the plants are being grown. condensed water from the apparatus above reaches the plants as drops. In order to take advantage of industrial methods for cheap manufacture, plastic bottles either new or obtained as waste can be used for processing.
