I haven't had time to read this entire thread yet, but the water storage thing caught my eye. There is a company called "LifeSaver" and they make self filtering water bottles and jerry cans that are good for several thousand liters of purified water. I originally had to watch a speech on TED as part of a college class, and this was a one of the topics. If this has been mentioned before, I apologize.
