#46 Desalination




As the planet heats up vast areas are experiencing extended periods of drought, from changing weather patterns. This is particularly true of subtropical areas such as the Southwestern part of the US, Australia, Africa and Europe. No animal, plant, or human, can live without water and future wars could develop should populations feel threatened.

Australia out of necessity, with a threatening extended drought, has been fine tuning the technology behind desalination plants to rescue the land from a potentially disastrous situation. By the process of reverse osmosis, salt is removed from sea water which then can be used for farming and human consumption. To date desalination has been technically difficult and expensive, but necessity drives innovation and man is in hot pursuit of a cheaper and technically simpler way to solve this problem. This piece is about desalination with the sea water being sucked into the bottom of the stick/pipe where it is then run through a valve at the top where the salt remains and the fresh water is then spewed out over the parched land.
