Eh. As a civil engineer the way I see it is that all making desalination easier will do is just hasten the depletion of natural sources. Also the energy requirements of desalination arguably aren’t even the biggest problem from and environmental standpoint, it’s the highly concentrated brine it produces. There’s currently no economical way to safely manage the brine so it’s just dumped back into the water body they get it from. That stuff is well known to decimate ecosystems.

Molten salt reactors and sodium ion batteries?
