Default Anyone make a solar still here?

Was looking at one a while back and can't find the video now, but a guy made a wooden box with a plate glass top that was at an angle. Then he waterproofed the box. At the bottom of the sloped glass, he made a trough out of a piece of PVC that collected the condensated water that rolled off the glass. The side had a PVC inlet to pour saltwater into. I like the basic design and was thinking of fabricating one for a project. Can someone confirm whether a still like this would remove everything except pure H2O? In other words could some contamination still end up in the clean water? I am thinking this answer is yes, some contamination could evaporate and condense on the glass and contaminate the water. Of course, salt would not and that would be the main purpose. Now, if contamination could pose a risk, would boiling the water make it safe? I'm not talking about using toxic waste, but just beach/coastal saltwater.

I would tend to agree that some contamination would exist. It is not a sealed system, the temperatures are not hot enough to sterilize, and bacteria/mold/fungus could grow in the box since it is a warm damp environment.
