MIT engineers and collaborators developed a solar-powered device that avoids the salt-clogging issues of other designs. Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun. In a pap
You could but estuaries are incredibly important ecosystems and increased salinity might be harmful to them. Arguably the best place is oceanic areas with strong currents to promote brine mixing with normal seawater. The worst impacts are where the brine sinks and does not mix, creating a dead zone on the sea floor.
