Jon Liow, Bachelor of Industrial Design at Monash University, has developed a portable device that purifies drinking water using heat from sunlight. The device, called a SolarBall, is designed to help people in developing regions access clean water.
SmarterPlanet describes the innovation:
The Solarball works by absorbing the heat from sunlight, which causes dirty water contained inside to evaporate. During the evaporation process, contaminants are removed from the water, leaving behind condensation that can be collected and stored for drinking.
