I was considering cities first with this, which I realize isn't the biggest use of this water but is part of it.

I also imagine with continued investment and research the tech could get better at scale too. It may be hard today but perhaps there's headroom for innovation with more funding while tackling migrating cities to using desalination

A single mid sized farm can use more water than a town of 30,000 people.

What’s affordable for a town is several orders of magnitude different than what’s viable for that farmer.
