Granted, this is used primarily in places like Africa (where the sun actually reaches out and slaps you across the face all day), but in an emergency situation this should be a viable form of procuring potable water. Particularly after natural disaster or something.

Oddly enough, I actually came across this on http://thereifixedit.com and wasn't sure it was legit until I looked it up.

Only downside is the requirement of consistent, direct sunlight. Other than that it's cheap, seems effective, and could be set up quickly and easily.

Thoughts?
 
I wouldn't personally do this unless I had no other means. If I had the time and the resources, I would rather just make a still. But if I had no other way to purify water, then I the SODIS method is better than none...

Well i think time and resources are the key words here.
The neat part about SODIS, is that it is almost zero effort and only requires materials that are lying around almost everywhere there are people.

Sure making a still would be cooler, but it would be a lot more work, more complicated and require different stuff.
 
SODIS is especially good for disaster relief and developing countries. It takes sun and time (contact time is minimum 6hrs, I believe), but it's great if you're not going anywhere, you need a lot of water treated, and you don't have the fuel or energy to use fire.

SODIS will not treat for metals or many other chemical contaminants. It's primarily for disinfection, which is usually the biggest water quality problem in disaster relief or developing countries.
