Developed by a team of researchers at Alexandria University in Egypt, the procedure uses a desalination technique called pervaporation to remove the salt from sea water
"It can effectively desalinate water with high concentration of salt like that of the Red sea, where desalination costs more and yields less."
There's also the issue of how to deal with the waste produced from the process.

According to the U s. Environmental protection agency coal-and natural gas-fired plants were responsible for one-third of U s. greenhouse gas emissions in 2012.
That's why the agency has proposed rules mandating dramatically reduced carbon emissions at all new fossil fuel-fired power plants.
