Well thatīs interesting point. Maybe somewhere where is not true free market someone doesnīt want to see this happening and wants to keep the price of the water high. Maybe there is other issue. I donīt know.
Recently I saw documentary A World Without Water. There were some people that had to use dirty water. I was thinking that several pieces of this cone or something similar would make a big difference and wouldnīt cost too much if it works as advertised.
I also donate some money to organizations and projects that should help a good thing from time to time and after watching this documentary I immediately sent some money to one of these projects that is designed to help in the areas without water because what I saw was quite rough and sad.
