Using salt water for light

Did you know that 97% of the water on our planet is salt water? 

A Columbian company, E-Dina, is working on a solution that uses salt water to create a sustainable lighting solution for off-grid communities.

The product, WaterLight, won innovation awards from TIME and FastCompany in 2022. Two cups of salt water can produce light for 45 days. Its life span is approximately 2-3 years or 5,600 hours of light and can be recycled afterwards.

This innovation works 24 hours a day and is not dependent on weather conditions unlike solar and wind. Originally designed for the Wayúu people, an indigenous community in Colombia, WaterLight has the opportunity to help the over 840 million people in the world who don’t have access to electricity. 

The future seems bright for this idea.
