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.
