Desalination is a process in which salt water is transformed into freshwater for human use. By pumping seawater into treatment plants, salt and other minerals are then filtered out from the water, making it suitable for irrigation, or even drinking (Micale et al. 2009) . The only requirement for desalination is supply of seawater and enormous amount of energy. With these two crucial elements, we can have a very reliable, and nearly unlimited supply of freshwater.
