You bet. Dad and I traveled (flew) to Puerto Vallarta in '84, we took the ferry over to La Paz, and found out that the water was drinkable there. No trots! The entire city was served by a huge desalination plant.
The bay, OTOH, was a filthy, stinking sewer. They didn't treat sewage and the city sewer outlets flowed directly into the bay. It was gawdawful.
I went snorkeling 13 miles down the road in pristine, crystal-clear water at Pichilingue Beach. When I reached down for a piece of broken coral, I couldn't pick it up. I then kicked for it and missed. When I dove for it, I found that what looked like it was within reach was actually over ten feet down! Amazing!
Anyway, they have reverse osmosis machines in all sizes, for hikers, sailors, and cities.
Ayup. Or pedal powered generators to charge battery banks?
Ayup, and only if you didn't want to eat it raw, respectively. (Ewwwwwww!)
Anyone else read _Life of Pi_? An eastern Indian boy is trapped on a lifeboat with a bengal tiger for 133 days. Fun story. It was primarily fiction, but the author mentioned fish behavior in it.
