E-Dina – WaterLight

At least 840 million people around the world are without access to electricity, hindering their ability to work beyond daylight hours. That insight inspired creative agency Wunderman Thompson Colombia and renewable energy start-up E-Dina to built a revolutionary device that can transform half a liter of salt water into 45 days of light. WaterLight is made from recyclable material and has an expected lifetime of around 5,600 hours. The product is available for purchase by NGOs, governments and private organizations.
