Transport Safe Water Easily

Nobody can deny the importance of water in our lives, so it’s rather obvious that in less developed countries, a source of clean water is essential. A recent design shows a very interesting idea of a rolling water carrier, but it also uses the motion of the wheels to drive a reverse osmosis filter through the water, giving folks a method to carry the water easily, and a safe purification means. The filters which last about a year will cost about £20 ($30). It certainly looks like something that can greatly benefit developing countries.
