文】Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren't there many factories like the Symi factory?
In some places the sun is not hot enough. Or it does not shine every day.
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. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out.
