Warka Water

Interesting video about a device that may make water shortages a thing of the past.

Update:

This looks like an air well.  It seems that I have looked at these before, but I cannot find the post on this blog.  Maybe I didn't make a post, or the post is buried somewhere in the blog.

Whatever.  The concept is not explained in this video.
