Did you watch that video ? It would certainly suggest otherwise.
You mentioned many areas not having potable water. Without more specificity, I have no idea to which areas you refer.
I do know that a major problem in third world countries is far more related to unclean disease carrying water than it is strictly to simple lack of water.
I’m not techy enough to explain it well, but I saw a 60 Minutes piece on Dean Kamen. He’s a multi-faceted inventor who does a lot of thinking ” out of the box”.
He demonstrated a self contained system he developed which could easily filter water to drinking standards for small villages at minimal operational cost.
I haven’t checked on whether he goes into that much detail about how it works on his website. But I found the demo he did fascinating.
Desalination and potability are two separate issues. It wouldn’t be necessary to transport desalinated water to a landlocked area if a simple filter system could result in potable water.
I’m going to go check out his website and see how much progress has been made on making his system more widely available.
