Can you explain this one? I'm trying to picture why one would have a tray of salt under the shelf, why it would have water in it, and how to drain the water wi

  My guess is that it is being used as a dehumidifier. The salt will absorb moisture from the air since it is hygroscopic. However, I can't imagine there being a significant effect without a lot of salt. The salt probably would not dissolve entirely, so you could strain it. Some dissolved salt would be lost each time. You could also cook/boil off the water, but that would require a lot of energy for an off-the-grid cabin.

Or moved outside into the sunshine under glass to evaporate. A large mistake I used to often make was trying to design self contained solutions. Keeping modularity in mind, and moving things about during the day solves a huge range of problems. A cast off sliding glass door makes an excellent alternative to herbicides - just lay it down on the grass. It also aids in heating water, drying clothes, meat, herbs - what have you.
