"WaterLight" Converts Saltwater And Urine Into Electricity

The world needs a clean energy revolution because billions of people do not have access to electricity. Colombian renewable energy startup E-Dina had developed a wireless lantern called WaterLight, that produces electrical energy from a renewable natural resource such as saltwater or urine.The portable device needs to be filled with 500 milliliters of seawater – or urine in emergency situations – to generate light for 45 days. This, thanks to the ionization of an electrolyte composed of saltwater, which reacts with magnesium and copper plates on the interior of the lamp to produce electricity. The WaterLight acts as a mini power generator and can be used to charge mobile and electronic devices via a USB port. It will also help fishermen to fish at night and will allow craftsmen to sell a higher amount of orders by allowing them to work at night. WaterLight works 24 hours a day through ionization, which allows the lantern to produce electricity, and light, for long periods of time, thanks to E-Dina’s patented way to sustain the chemical reaction over a prolonged period of time. WaterLight has been created as a 100% recyclable and durable product. It is designed to run for 5,600 hours – which equates to more than 230 days or 2 to 3 years of use, depending on how often it is needed. ​Credit: WASTE ED
