In such places, other ways of heating sea water can be used．These ways cost more money, but they work faster than the sun．By boiling sea water with high heat, a lot of fresh water can be made quickly．

But heating is not the only way to get fresh water from salt water．Other ways are tried．

One way is freezing (冷冻)．The fresh part of salt water freezes first．To get fresh water, the bits of ice are taken out．

Which way is the best? The one that gives the most water for the least money．There may be a different way for each place．

Symi’s way seems very good for small, hot places．It does not make very much water at a time．But the factory is easy to build and costs little．

That is why people in many dry places talk about Symi．
