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.
You have good points, but why so rude? Especially since as @jadero@mander.xyz showed that while they might be reasonable concerns, doesn’t mean there’s no solution for that, or that no one would think of that.
Because this kind of thinking is dangerous. It pulls attention and funding away from real solutions like water usage efficiency and reclamation
