As much as I would love to get a solar or wind system, I'd rather pay off my debt and get a piece of land somewhere outside the city. My biggest concern at the moment is my water supply... if the city water goes bad, then we are pretty much done because there is no good way to get around that other than collecting rain water (which I do on occasion in some plastic storage tubs, just to water my potted plants). The rain water I do collect is questionable... it doesn't look drinkable. It's cloudy greenish yellow. We are in a high humidity area, so I'm sure the ecoloblue system would work fine here, at least it gives me something to think about. Thanks for the info all (and Wellspring, I'll let you know for certain! Thanks).
