“Rainwater collection that is used for gardening purposes is finally legal in Salt Lake. So we can finally have our Rainwater Harvesting workshop again!”
Unfortunately, sane people in the arid zone of Arizona were unsuccessful in a recent attempt to allow private rainwater collection, even though the downstream residents the law was designed to protect will have most of the uncollected rainwater evaporate before it reaches them. So it’s a loss for everyone.
Perhaps toilet-to-tap recycling like in Big Spring, Texas will solve Arizona’s drinking water shortage.
The Discovery News subtitle is “The drought-stricken town is taking a page from NASA, which developed a urine recycling program for astronauts.”
The Slashdot poster explains:
“After being run through microfilters and undergoing reverse osmosis, slimy sewage is cleansed with peroxide and ultraviolet light. This intense process ensures that any pharmaceuticals and carcinogens are removed, and that the H2O stands up to drinking water regulations.”
Coming to a water district near you? The Discovery News article interviews a big city DWP honcho considering a similar scheme and reports that 41% of America is abnormally dry.
“Plants fertilized with a mixture of stored human urine and wood ash produced 4.2 times more fruit than plants without the pee, the study found. The urine-fertilized tomatoes had more beta-carotene than unfertilized ones, and much more protein than traditionally fertilized plants.”
Speaking of NASA, click image of the view of Earth from Apollo 8 over Rama’s interior to see a list of O’Neill cylinders and other space habitats.
The Story of Stuff, an entertaining “consumption run amok” video presentation, illustrates the limitations of conventional recycling. For every barrel you recycle, 70 barrels of waste were required in manufacturing the item. And just 1% of the things people buy are kept six months later, the rest is trash. (Makes my iPod seem not quite as bad as Greenpeace made out in 2008).
Speaking of cradles, the book Cradle To Cradle: Remaking The Way We Make Things calls for true recycling as might be needed offworld in a self-contained habitat, according to Amazon:
In Cradle to Cradle, the authors present a manifesto calling for a new industrial revolution, one that would render both traditional manufacturing and traditional environmentalism obsolete. Recycling, for instance, is actually “downcycling,” creating hybrids of biological and technical “nutrients” which are then unrecoverable and unusable. The authors, an architect and a chemist, want to eliminate the concept of waste altogether, while preserving commerce and allowing for human nature.
