I think the biggest thing this new wave of water desalinization evangelists are latching onto is tightly integrating green energy sources into the process to effectively offset the energy costs (economically and ecologically). But honestly I can't tell if it's really a new generation of designs that'll make desalinization feasible where it currently isn't, or just another example of green washing.

For the basics, practical engineering did a good video on desalinization: https://youtu.be/mxqOPdEUNTs
