This Device From DARPA Makes Water-Cleaning Chlorine From Salt And A Car Battery Mountain Safety Research's Community Chlorine Maker (now on Indiegogo crowdfunding campaign that can be supported at http://ift.tt/2ecq9Kt with 13 hours to go before it closes) was first developed at DARPA; it was standard issue for the Marine Corps for a time. But it's taken new engineering and user experience design to make it a mainstream device, usable even by people with little education or training. The camping light-size device can make enough chlorine to clean 200 liters of water in just five minutes. All villagers need is salt, water, and a decent car battery; the residue is a thick, white chlorine about an inch high. The Indiegogo campaign looks to raise $50,000 to fund the manufacture and distribution of 2,500 units through two other NGO partners: World Vision (Kenya, Mali, Bangladesh) and Operation Blessing (which took units to Haiti after the recent earthquake).
