Solar Pura is an appropriate technology project aiming to provide safe drinking water by harnessing the power of the sun. Around two billion people lack access to clean drinking water across the globe and many of them live in arid and remote areas perfect for the implementation of highly efficient, low cost, small-scale solar stills. Solar Pura is a water purifier designed to produce enough fresh water in a sunny climate to provide for a small family’s daily needs. The design is optimised to be lightweight, low cost, robust and user-friendly. This scale functional prototype has been tested giving promising early results for this novel technology.
