ok…
it needs some experimentations, however it seems to work very well…
This NaCl peculiarity comes from its high value of the heat of fusion(about 300 kwh/m3 – in addition a little salt mine can easily contain 100 millions m3 of salt…) .
It means that solar energy can be used to melt the salt, then it can release heat constantly…
Do you agree?………..
If you could find a cheap way to store the salt, insulate it and melt it, you might have something. I think the limiting factor would be storing it as a liquid. What would it be contained in? Would it be cheaper than pumping water up a hill?

Not really sure I see a question here…molten salt is already used in a number of solar thermal power plants.

Generally speaking, free markets find the most efficient methods of achieving desired ends.
(part of the beauty of the free market is that when a new thing is more efficient than the old thing, people willingly and eagerly make the transition to the new thing.)
This apparently has some promise, but has yet to cross critical efficiency barriers. When it gets there — if it can — it will certainly be used.
If you can find a company that does this, I’m sure you could pick up the phone, tell them you want to learn, and find out a great deal about their accomplishments and challenges.
