Here are a few more concepts and variations of solar stills, some have quite an output of clean water per area used.

The "Collection Trough" can be piped into quite a large cistern,(even pumped to a tower to add water pressure), for holding to a later date. After all, since you are using the power of the sun to distill water, you might just as well use the sun to create electricity for the pump also.

You have to admit, the output on some of these are far higher than the old style of "Pit" solar still. Even though that type is certainly an excellent option. Especially in an emergency situation as the materials that are required to build one of the pit types can be carried in a backpack.
