To make solar power viable, we need a solution for overnight energy storage.

Batteries are complicated.

Do you know what isn't? Water go up. stonks-up

No, saltwater is corrosive, pure salt is not.

Cool good to know, but why do they need to keep cleaning the pipes?

Some of molten salt crystallizes on pipe walls, because they are colder, and it makes the pipe narrower.

Just from reading here a bit there seems to be some corrosion though. My chemistry is to shit atm to understand it though

making it necessary to mitigate corrosion by either purifying the salt, controlling its redox potential in a reducing state, or using redox buffers

The salt is not pure enough, it seems.
