A group of industrial designers have developed a fantastic technology for purifying water in developing countries. The product is known as the "Life Sack" and it uses a solar water disinfection process to purify water. However, what might be most ingenious about this product is that it is designed to also serve as a shipping container for grains or other staple foods. Food is shipped in the bags and then turns into a state of the art water purification system.-William Muck
