(anyone else see the irony here… Miguel Cervantes, …Don Quixote, Windmills?) Electricity for the desalination plant, which has an overall 24MW requirement, comes from the new 80MW Emu Downs Wind Farm, located 30km east of the town of Cervantes. Perth Australia has now established one of the outside of the Middle East and set up a wind farm to power it. Well in Perth Australia they are doing exactly that. One of the readers last week commented that use of wind turbines or wave energy to power desalination would be a great idea. I’m going to highlight a few different ways in which renewable energy can be used to produce drinking water. Its more a case of ‘water water everywhere and not a drop to drink’. With seawater covering seventy-one per cent of the Earth’s surface, at an average depth of four kilometers, and another 1,000,000,000,000,000 liters of water in the first kilometer alone of the earth’ atmosphere, water could hardly be described as a rare element.
