Why don't we get our drinking water by taking salt out seawater? (2008)

A mirror of Hacker News' best submissions.
This is actually done on a massive scale in Israel, around half our drinking water is desalinated.
Egypt does this as well. Well known tourist region Hurghada gets nearly all its drinking water from desalination.
I do believe they do that in qatar as well
Part of the reason its the most co2 emitting country (per capita)
