Science Buddies: "Ask an Expert"

My topic is "Can you use solar energy to purify salt water,". What I have done so far is my hypothesis and statement of purpose and know I need my research. I'm trying to purify salt water with solar energy so is it possible? Also,if its possible is it cheaper to get it from a factory or by using the suns energy?
