Desalination is a very specific method used to generate freshwater where rainfall, rivers, and reservoirs fall short<\/a>, but there can be a problem: this usually comes together with a very high electricity bill. That problem is not just a small thing that happens to some parts of the population\u2026 The Water Development Report<\/a> says that 2.1 billion people still lack safely managed drinking water, which means that even where a supply exists, it is not always managed in a safe way.<\/p>\n\n\n\n

The sea does work normally assigned to pumps<\/h2>\n\n\n\n

Why did the company decide to go 500 meters down for the most difficult part? At that depth, the ocean water naturally can exert 50 bar<\/a>. This would be almost the same as what a conventional coastal plant<\/a> can create, but with the difference that those end up consuming a lot of energy. Also it is important to explain that at this depth, and the reverse osmosis depending on the pressure, most of the salts stay behind.<\/p>\n\n\n\n
