Seawater Desalination System

Seawater desalination device that extracts magnesium from seawater

There are 1800 trillion tons of magnesium (100,000 years’ worth of oil equivalent) in seawater around the world. How to get this out was a big issue. Previously, an electrolysis method was proposed, but it requires a huge amount of energy, so magnesium made this way cannot be used in a decarbonized society. In addition, there are seawater desalination devices such as RO (reverse osmosis membrane) membranes, but these are for making drinking water from seawater and are designed so that salt and magnesium are discarded as unnecessary.

Professor Emeritus of the Tokyo Institute of Technology, Prof. Yabe proposed the world’s first seawater desalination device specialising in magnesium sampling. Here’s what this looks like.

Support for existing equipment (remora plan)

Existing seawater desalination equipment, such as reverse osmosis membranes dump seawater containing high concentrations of salt and impurities into the ocean.

Use Yabe’s freshwater equipment to solve this problem. We will call this the remora project.

This is because nothing should be done except sticking to a huge shark called the reverse osmosis membrane method. In the reverse osmosis membrane method, fresh water is produced and high-concentration seawater is released with three seawater inputs. This is the cause of the problem, so with Yabe’s device, you can generate fresh water from this high-concentration seawater and solve the pollution problem. This plan will solve the pollution problem of existing equipment and triple the amount of fresh water produced.
