In the developing world, access to safe drinking water is a major concern and people often have to walk many miles per day to bring potable water back to their homes and families. According to reports, water-borne diseases kill more people in Africa than war and violence which is a very telling sign of the scarcity of pure water in the region. Water purification using UV rays is one of the more popular methods these days though most such apparatus are not geared to meet the challenges faced by people who need to walk several miles per day to get water. Created by Marcus Triest and Ryan Lynch, the Solar Bag is one creation that seeks to tackle the problem of water purification while it is being transported from the source to homes by the locals.
