Greywater Blackwater RecyclingOption Sahara means gray water recycling. First thought of for very water-poor countries, but suddenly this is also interesting for Germany.A few years ago, I spoke with a farmer. Not just any farmer, but Wolfgang Löser, known as an energy rebel. He said “phosphorus is running out”. I replied ironically “I would not be aware of an enemy invasion fleet transporting phosphorus away from Earth”. But the serious background: there used to be the short cycle, outhouse, manure pile and bring it all back to the field. What opportunities are there for recycling when very cheap electricity is available? For a civilization to exist in the long term, it is necessary to perfect recycling more and more. If 99% recycling rate may be enough for a thousand years, 99.999% is needed for a million years. GEMINI next Generation is not just any house, it is the prototype for a very long surviving civilization. |
