As global populations increase, the demand for fresh water is beginning to exceed the supply. Desalination technology offers a promising solution by converting seawater into water for human consumption. The most common method used today is reverse osmosis, which forces water through a semi-permeable to remove salts. Despite its potential, the process remains energy-intensive and can be quite to operate on a large scale. Furthermore, the disposal of highly concentrated brine back into the ocean poses a significant to marine ecosystems. Engineers are now researching alternatives, such as using solar power to drive the desalination process.
