Desalination system could produce freshwater that is cheaper than tap water

According to a quick Google search,

> On average, about 35 g of salt is present in each 1 kg of seawater

so if those 700 billion kg of water for LA all came from desalination, that would yield 24.5 billion kg of salt.

That suggests we could have 12 LA-sized cities relying entirely on desalination before we'd saturate the world's demand for salt.

"Could have" is doing a lot of heavy lifting there. Assuming spherical cows, 12 is an upper limit, okay. What you could actually do is neither remotely close to that nor is that itself remotely close to what the world needs, was the point.

The demand for salt is already saturated. It's a mature worldwide industry.

Adding your 12 cities would double the supply.

Salt filled with micro/nanoplastics.
