great article but it tries to (ahem) separate drinking water from other uses, which doesn't seem practical: - in the poorest places, they can't afford desal. -

great article but it tries to (ahem) separate drinking water from other uses, which doesn't seem practical: - in the poorest places, they can't afford desal. - in non-poorest places, most water is delivered by unified piping systems due to cost and labor efficiency. Schlepping water in bottles and buckets is nuts, though I can see it turning into the next weird fad in exercise or robotics.
