Looks expensive and complicated. I still think a clear plastic gizmo that just uses the sun to distill that merely cleans most toxins, especially biological is better than some giant refrigerator sized, patent encumbered, machine that needs to be plugged in that cleans all toxins.

The little plastic thing could be made so small, so light, and so cheap that they could just be dumped out of the back of airplanes where they are needed.

How do we teach the villagers how to use them? Call them on their cell phones. http://www.iht.com/articles/ap/2008/03/03/africa/AF-FEA-GEN-...
