A Colombian designer has collaborated with renewable energy company E-dina and Wunderman Thompson to build a lamp that generates light using salt water. It could help over 800 million people worldwide with little access to electricity.
Ever been stuck out in the wilderness without a torch? Phone run out of battery? It’s an inconvenience that can happen to any outdoor enthusiast.
A new sustainable lamp could be the answer to your problems. Created by designer Miguel Mojica in collaboration with E-dina and Wunderman Thompson, this new innovation is called the ‘WaterLight’ lamp and is able to convert seawater into electricity.
Think of it as a cross between a battery charger and a traditional torch, a handy tool to provide energy to those in remote areas or tricky situations. We don’t have access to an electric grid everywhere we go, after all.
How does it work, you may be wondering? WaterLight draws electricity from ionising salt water. Electrolytes in the salt water react with magnesium and copper plates inside the lamp, which is then converted into electric energy.
Half a litre of water is able to produce light for 45 days and can be recharged with urine, should the need arise.
