The researchers are in Australia, where we have abundant coastal land that is not suitable for agriculture. Indeed there are many salt lake systems already being used for large scale salt production via sea water evaporation (https://www.riotinto.com/australia/dampier-salt-4644.aspx https://www.riotinto.com/australia/dampier-salt-4644.aspx). Should this type of technology scale out, some of these salt production operations might also be able to produce desalinated water either for domestic or industrial use (in the case it is still too brackish for drinking).
