That all seems reasonable.
There was an item in a doco a while ago (I think it included the CSIRO) and they seemed to be interested in using water absorbent crystals (sodium polyacrylate I guess). Used less water and lasted longer. Their demo looked quite impressive. I have no idea how it would be "sprayed" on to a home in practise though.
There seem to be quite a few commercial systems; but I guess I was wondering about their underlying theoretical basis ? regards Rohan McLeod
