More off-grid water distillation ideas

Another water subseries post in the main series of off-grid posts.



I've got three different videos to study here.  This first one uses a water bottle, and can be carried around with you.  Its virtue appears to be in its compact size.






The next video shows a simple design that anybody can make.  It doesn't make much water, but it has the virtue of being made of discarded materials, so it doesn't cost much.  You can make a lot of them in order to make a lot of water.







The last video is even more radically simple.  It uses a can and a plastic bottle.  The plastic is folded in on itself, and collects the condensed water.  Very clever.  I like this one because it may actually do the job.  The dark colored can will get hot in the sun.  The heat is trapped, so the water will get hot enough to evaporate.  It has no place to go, so it will condense and trickle to the bottom of the bottle, inside the folds.
