Herbert Greene, David S. Jenkins, G. Drouineau and Richie Calder discuss the saline water problem. They explain that a large part of the world does not have access to enough fresh water for their needs, including drinking and watering crops and animals. Salt water from the sea or other sources is more widely available, and the speakers explain that if the problem could be solved of how to efficiently turn salt water into fresh water, it would have many important applications. The speakers provide some general definitions and contextual information to better understand the different aspects of this problem, and go over the details of different projects across the world that are currently underway in addressing this problem.
