Thinking Moon

The Sodium entry is a good example of thinking Moon. That is, looking at ideas that are insignificant when used on Earth but could really save the day when used on the Moon. It does take a rather long scenario to show how Sodium could be used, but this is part of the process needed to compare complicated technical ideas.

Indeed ISRU is important.
I can't see sodium being much use as a conductor inside a habitat due to it's potential for interaction with condensation. Neither can I see much use for NaK in a hab, though that might have uses outdoors.
I've forked Sodium Scenario to it's own article, partly because it deserves an article and partly because this page is intended primarily as a fact resource for other articles.

Sodium Abundance

Having looked around I'm only seeing Sodium in the 3k ppm range or listed in compounds that have % occurrences of ~0.5%. Could you cite your sources supporting said abundance of Sodium?
