mistermack Posted August 16, 2022 Share Posted August 16, 2022 I've dreampt up a speculative scheme for greening a desert. Do you think it would work? (or be cost effective?) You need a desert that extends right up to a significant sea or the ocean. Like lots of Australia, or Namibia etc. Australia would be the best to try it on. Imagine you set up a huge array of pumps along, for example, the Great Australian Bight. Connect the pumps to spray nozzles, and start pumping when there is an onshore wind. Adjust the jets for a spray that evaporates most of the water, before it falls back into the ocean. So basically, you are manufacturing water vapour, from sea water, with the salty residue falling back into the ocean. So with an onshore wind, all of that humid air is carried inland, where it rises on thermals, forms clouds and rain, greening the land. If the wind blows the other way, you switch it off. Obviously, it could only be done on a national level, so that the benfits could be taxed and provide financing for the running of the system. Besides providing land that could now be used for agriculture, it could raise the level and quality of groundwater, cool the climate with more cloud cover, and actually get rivers flowing and lakes filling. If it worked. Any thoughts? Link to comment Share on other sites More sharing options...
