Discover WaterLight, an innovative invention from the Colombian startup E-Dina that transforms salt water into clean, renewable electricity.With just half a liter of seawater, this compact device can provide up to 45 days of light and power. It’s a solution that offers hope to millions of people who still live without reliable access to electricity.

The Innovation

WaterLight generates energy through ionization – using the natural properties of salt to convert magnesium into electrical energy. The lamp is portable, low-maintenance, and can also charge mobile devices. Where traditional power sources are out of reach, WaterLight brings independence using nothing more than salt water.

The Impact

Around 1.5 billion people worldwide still live without reliable electricity.
And with global energy demand expected to rise by 70% by 2035, finding sustainable alternatives has never been more urgent. WaterLight not only illuminates homes, but also powers phones and essential devices, helping off-grid communities stay connected. In coastal regions, it’s even used on fishing boats, making night fishing safer and more efficient. Through one simple innovation, salt water becomes a source of light, opportunity, and dignity.

Globally, around 1.5 billion people lack reliable access to electricity.

A New Perspective on Energy

WaterLight shows that true innovation isn’t just about technology — it’s about changing the way we think.
Energy becomes something deeply human: born from ingenuity, simplicity, and respect for nature.
Where we once depended on large infrastructures, WaterLight proves that the future can shine from the smallest of sources.

The story of WaterLight reminds us that progress begins with imagination —with the courage to rethink what’s possible and to let small ideas grow into something powerful.

At Nami, we believe this is the true power of storytelling:
making behavior visible, giving it meaning, and helping positive change flow further.
