Salts might be helpful in water-based systems where you want to avoid freezing, and the problems that brings. Keeping the system in a liquid phase does allow for circulation, further evaporation and so on. It would bring it's own problems too, of course, such as corrosion.

Addit: This leads me to think we should have forum challenges for things like this. Lots of bright people from diverse disciplines trying to come up with simple, real-world solutions for real-world problems. :)
