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.
Yeah just looked this up. So the numbers ay not be perfect.
But at 3.5% salt in sea water. 6l of water will produce 210g of salt.
6g is the max recommended per day intake. So let’s round down to 200g a day. X 365
76kg of salt per person per year. A small sea side village (1000) would be a dead-sea side village in a few years.
Also worth noting. While the dead sea is about 33% salt so 10x most living seas.
It would take well under 2x the salt level for fish to start dying in large numbers. So making the sea dead. Just as a fresh water fish would dehydrate due to excess salt drawing water from its cells in sea water. It would only take a small increase in the salt water vs cell salt content for sea fish to die.
PS 2l worth or 70g of salt will kill most humans without drastic care.
Just found looking that up interesting so thought id share.
