This coin is not a bad idea, but I never liked the cleanwater charity group because just focusing on giving people clean water is not enough.
Most smart people in 3rd world countries will boil or filter unclean water, collect rainwater and water from clean sources, they will not drink out of puddles in the middle of a paddy with a cow standing overhead like some pictures suggest.
Another thing, if your life really sucked and you have spent all your life drinking filthy water, you wake up the next day with cleanwater, would it really matter? It still doesn't change much.
What is important are the people need to be educated, then gain employment so they can afford decent dwellings. That is what charities should focus on, building up the local economy.
WTF are you talking about? There are parts of the world where water cannot be "filtered" by anything. Also, do you really think they are out there boiling all there water? Do you know the time and energy it takes to boil just a small amount of water, much less collect condensate, which is really need for extremely polluted water. Many people drink from a major water source such as a river that you and I wouldn't go within 100 yards of, I really don't think you have a clue as to what you are talking about.
