Desalination system could produce freshwater that is cheaper than tap water::A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.

Nothing about this is "new".
Evaporating water and catching it has been the way to produce fresh water since, like ever. But it's slow, and prone to bacteria.
The “new” is the way they’re doing it
Apparently they solved the issue of how to keep the waste salt from clogging up the system.
No they didn't. It's never been an issue. Just don't evaporate all water and use a new batch of salt water before the previous one gets saturated. Availability of salt water usually isn't the issue.
The question with desalination is always the same what will you do with the salt ?
If it was just salt it wouldn’t be a problem. Salt is an essential nutrient and industrial product and we actually run seawater evaporators today specifically to farm the salt. We mine salt out of mountains and ship it around the world. Salt is our friend.
The actual question is what to do with the concentrated salty sludge by products.
Pipe it to mcdonalds.
French fries are already too salty. And then, people gonna need freshwater. Infinity loop.

What about stopping shitting in fresh water ?
I tested a dry system with sand, sawdust and straw, but none of the other users was a fan :(

I imagine actually applying your solution would cause quite some friction.
I can't see why, we also had the three seashells system https://screenrant.com/three-seashells-demolition-man-function/ :)
Ofcourse. But that is because the seashells are the obviously superior method. The friction is with the sand and sawdust method.
