Desalination system could produce freshwater that is cheaper than tap water (news.mit.edu)

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.

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.
