Water is a luxury many can’t afford. As ridiculous as this may sound, it is true. Billions of people in the world lack access to safe water and are exposed to diseases such as cholera and typhoid. This is why a Swedish social enterprise invented Solvatten, which means ‘sun water’, a combined portable water treatment and water heater system that comes inform of a solar-powered jerry can. Solvatten, works by simple practical technology. The entire process of purification by heat and light only takes about two to six hours, and the water gets heated up to a 75 degree Celsius (167 Fahrenheit). A ‘smiley indicator’ by the side of the jerry can let the user know when the process is complete when a sad red face turns green and happy. The solar-powered water purifier is present in over 20 countries globally. The purifier also helps reduce the use of firewood and charcoal to heat up water, consequently solving pollution issues as well.
