Not really seeing much here in the way of details, which always makes me worry;

Are they using rare-earth based catalysts to control some chemical reaction? It's corrosive so will always break down parts, so have they extended the life by 10x or 1,000,000x ? Storing heat in this medium leads to thermal losses I'm not seeing a mock-up of how it's proposed that this is minimised. Surely trying to store high-energy corrosive materials at high-temp is dangerous even at this modular scale?

Naively this sounds like their solution to "saving the world" is "boiling acid" which is at least novel...
