  • Jul 27 2011: Waste of Water. City's have very complex installations and systems to provide water for direct drinking to every house in the western hemisphere. For teh sake of the discussion we only use 2 liters of water every for actually drinking. The rest of our water comsumption is wasted for kooking / washing / gardening / cars / and in bathsrooms. How much energie / money is wasted to get rig of the last inperfections out of our drinking water. Lets safe energie to not do this. Provide houses with clean enough water and give away free drinking water te everybody. Rain water fallen on rooftops makes excellent soft washing water, requiring less detergents and much less energie. Why do governements do not support investments in innovative ways to save energie.
