Interesting. I had no idea the melting point of sodium was so low. The usual considerations for skepticism of battery technologies apply: - mention of a membrane. This is present in all sorts of battery technologies and tends to have weak points around cost and lifetime. - poor passive safety. Standard lithium cells are usually tested to be puncture-safe. A tank of molten sodium cannot be puncture-safe, it will catch fire when exposed to air. So if something breaks off a plane and gets fired through the wing, the plane will become a fireball in the air. - alkali rain. The touted benefit of being able to dump sodium hydroxide into the air omits to mention that you shouldn't get it on your skin. Yes, it will be dipersed if it's dropped from high altitude, but what about the rest of the flight? - the chemtrail people would then be literally correct
