Saltwater corrodes firefighting equipment and may harm ecosystems, especially those like the chaparral shrublands around Los Angeles that aren’t normally exposed to seawater. Gardeners know that small amounts of salt – added, say, as fertilizer – does not harm plants, but excessive salts can stress and kill plants.
Why cant it be turned into sea salt (the “spice”)?
I don’t know, but if I had to guess like everything else it comes down to money. It’s energy intensive to desalinate seawater to the degree it’s drinkable, and now we’re talking about adding even more energy to refine it even further to make it suitable for human consumption. That makes any recovered salt expensive compared to natural salt deposits. Much easier (read: cheaper) to just scrape salt deposits that have already evaporated.
It is. But there’s way more salt produced that way than the market wants to buy.
There is work to combine lithium extraction with desalination plants. We would also have more lithium than we would ever need for batteries.
Is there lithium in seawater?
In small amounts. It’s not economical at all to extract on it’s own, maybe as part of desalinization, but even then it’s probably marginal.
Yes, lots. More than we could use.
Artificial scarcity from Capitalism yet again!
We want to desalinate water so that we have fresh water.
Doing so generates salt as waste and requires safe/responsible disposal.
We can sell some of the salt, as a product.
But the market won’t buy all of the salt.
So the salt just goes back to the “waste” category, and we need to find disposal methods.
I don’t see where scarcity (whether artificial or natural) comes into play. The world has lots and lots of salt, and anyone who wants it can get it very cheap.
Constitute it into bricks and dump them into old salt mines. Itll at least slow down mine erosian.
