The best way to make water drinkable


San Diego recently invested a billion dollars into a desalination plant to convert Pacific Ocean saltwater into as much as 56 million gollons of drinking water per day

As of 2013 Dubai was sourcing over 98% of its potable water supply from desalination

The process/cons

With a world that is made up of 70% water this shouldn't be much of an issue but unfortunately most of the water that we have is salt water not fresh water

For the average desalination plant right now, it takes 2 kilowatt hours of energy to produce 1 cubic meter of fresh water. Although that translates to a cost of under $2

The sea as a source of drinking water seems to be unlimited, but pollution by land-based activity often impairs the quality of coastal water bodies that serve as feedwater for desalination plants
