A desalination greenhouse includes a method of fresh water production hybridized with growth and production of a crop. The co-location of a growing crop can provide additional economic incentive to a hybrid system, and provide a moisture enhancement to an internal atmosphere which can be utilized to more efficiently produce and yet benefit from the production of water without the salt content, and as well to concentrate the salt content of brine which is used in another salt production operation. A further substantial achievement could be obtained by desalinization of water by using renewable energy economically and saving 95% of water normally used in open field irrigation of crops.
