Abstract: An apparatus and method for the desalinization of salt water utilizing a humidity chamber under partial vacuum and a water collection structure to collect fresh water product. Saltwater having a first temperature and cooling water contained in a condenser having a second temperature lower than the first temperature are introduced into the humidity chamber via a solar powered vacuum pump. A temperature gradient created by a difference in temperature between the saltwater and cooling water in combination with a partial vacuum (e.g., 10-20%) created by a solar powered vacuum pump is used to distill salt-free water from the saltwater with high efficiency. The temperature gradient is created in part by the use of a salinity gradient solar pond. The salt-free water is obtained by condensation of the water on a collection surface cooled by the cooling water followed by collection of the water in a storage apparatus.
