This could have a huge impact on rural areas of the Middle East and North Africa, where access to clean water is a pressing issue if social stability and economic development is to improve.

Right now, desalinating seawater is the only viable way to provide water to growing populations, and large desalination plants are now a fact of life in Egypt and other Middle Eastern countries.

Most of these plants rely on a multi-step process based on reverse osmosis, which requires expensive infrastructure and large amounts of electricity. These plants release large quantities of highly concentrated salt water and other pollutants back into the seas and oceans as part of the desalination process, creating problems for marine environments.
