New Lantern Is Better Than Solar and Can Be Charged

Posted by in categories: energy, sustainability

Colombian renewable energy startup E-Dina developed a wireless lantern, called WaterLight, that converts salt water into electricity and is more reliable than solar-powered lamps, a Dezeen article explains. And it can also be charged by urine in emergency situations.

The portable device acts as a mini generator that produces light using ionization — by filling it with 500 milliliters of seawater, the salt in the water reacts with magnesium and copper plates inside the device, converting it into electrical energy.
