A. For many of the world's coastal cities and regions, a strange problem exists: they are surrounded by a massive amount of water, yet they do not have enough of it to drink. Seawater, with its high concentration of salt and other minerals, is unsuitable for human consumption, agriculture, or industry. As populations in these areas grow and climate change affects traditional freshwater sources like rivers and rainfall, the need for a reliable and consistent supply of fresh water is becoming more urgent. This has led scientists and engineers to look towards the ocean as a potential solution, using technology to remove the salt from seawater in a process called desalination. B. Early attempts at large-scale desalination primarily relied on thermal methods, with Multi-Stage Flash (MSF) distillation being one of the most common techniques. This process works in a way that is similar to the natural water cycle. Seawater is heated in a series of chambers, causing it to boil and turn into steam, leaving the salts and other impurities behind. This steam is then collected and cooled, condensing back into pure, fresh water. While effective at producing high-quality water, MSF plants are ext…
