Comment on Desalination system could produce freshwater that is cheaper than tap water

We have destination where I live but the problem is this: the water often smells like fish. And it’s very hard because they use so many chemicals.
I don’t think desalination is the solution.
This circulation, combined with the sun’s heat, drives water to evaporate, leaving salt behind. The resulting water vapor can then be condensed and collected as pure, drinkable water.
This is not a chemical desalination. It's a classic solar distiller. The output is distilled water. You actually want to cut it with a bit of seawater, because drinking distilled water pulls salts and minerals out of you, and then you die.
Drinking distilled water is actually not that dangerous, so long as you get salts some other way (food!). In order for distilled water to cause runaway deplasmolytic processes, you’d need to spend a lot of time only drinking that, afair from high school bio.
I mean you die if you only drink distilled water and never consume anything else, but the same is still true of mineral water
I was unclear - that's exactly what I meant. I was thinking fo a suitcase-sized still being used in an emergency or survival scenario, for a time anything other than "very short term."
Around half of Israel’s drinking water is desalinated, and I’ve never encountered what you describe.
Not from Israel but our entire water system is desalinated and I’ve never experienced any issue with the taste, in fact the opposite is true. Pure clean drinking water.
I will agree with the hardness aspect but other than that it’s perfectly good, i’ve tasted worse bottled mineral water.
Producing clean water is a multi-faceted problem, your locale may require a different or multiple different solutions.
Multiple solutions are often nice cause you don’t have to rely on a single solution if one goes down or has issues.

Solution to what?
Literally all rainwater comes from solar-powered desalination. There is nothing better than that.
