[QUOTE="mindlight, post: 74626776, member: 21246"] I mentioned the Bradfield scheme in my OP and yes it had a number of miscalculations. But the basic idea of diverting the massive excess rainfall of the Summer monsoon across the mountains so that they flowed down towards Lake Eyre was a good one and once the pipes were in place could be done by gravity alone. There are already natural channels in place but only occasionally activated. The benefits to the eco system of a more regular flow are the advantage here. Again there is also already a natural lake at Lake Eyre which fills naturally 4 times a century. What is being proposed is filling it permanently. Desalinated water from the South only requires a pipe line and given that Lake Eyre is at the moment below sea level the pumping or flow of water need not be too energy intensive. It also appears that at some time there may have been a natural channel from Lake Eyre to the coast at Port Augusta, so digging a water way navigable by canal barges and cargo ships is not as problematic as it sounds. Noone is talking about watering the whole of Australia the scheme I propose simply activates natural waterways and lakes already in place and restores the possibility of vegetation on their borders. This opens an enormous amount of potential space for cultivation and habitation as well as whole new economic zone deep in the interior. Also the scheme rests on desalination plants using reverse osmosis technologies that reduce the cost of kiloliters of water to only 50 US cents. That is competitive with aquifiers. A rich country like Australia can make an executive federal level decision to make something like this happen. The reason why it should do this is threefold 1) The country has exhausted many of its natural aquifiers and these must be replenished to avoid a future catastrophe and to allow for future population growth and ecosystem stability. The present strategy is unsustainable and their is a massive strategic risk and vulnerability in allowing cyclical droughts and normal times to become the norm. 2) The space at the heart of the country is wasted but could be utilised with a step by step approach starting with something like a lake Eyre project. This is about growing Australia and turning its assets into something productive. 3) Global warming is a growing problem around the world and the desertification of Australia is a contributing factor. If you can turn your dry interior soil which is radiating heat into the atmosphere into vegetated spaces using sunlight to produce life and suck in Carbon dioxide with forests etc then you reduce Global Warming and in fact its impacts on your country also.
