How To Build An Inverted Solar Still
I don’t know where I have been for the past 5 years but I actually have never heard of an inverted solar still. An inverted solar still is pretty much the same principles of a normal still but with a normal still you have to dig a deep hole and sometimes that isn’t feasible in an urban setting.
This still isn’t going to produce large amounts of clean water so I would recommend using this to back up other methods of collecting water. I guess you could make a lot of them and leave them to produce the water all day, if you had the materials.
I like that you can use items around you to construct this still. In an urban setting making these stills would be pretty easy.
You can only go 3 days with out water so any water you can get is better than nothing at all. Check out how to make these pretty cool stills in the link below and the materials are light enough you can use these if you were going to be bugging out too.
