Yeah if the main insight is "you can run electric dialysis desalination on variable input power" they sure did a lot of dressing it up.

Desalination that can start and stop, increase or decrease activity, without messing anything up is the secret sauce here.

Not going to do that with reverse osmosis systems.

That said, with merely brackish input water, I'm wondering how many problems this really solves. Drinking water, sure, but you have to get rid of the concentrated brine at the end and it's still groundwater that can be overdrawn.

However, if v 2.0 can effectively desalinate ocean water, it would be huge for islands and coastal areas.
