Salt water lamp WaterLight set to power communities without electricity


The compact device takes inspiration from indigenous practices at the borders of Venezuela and Colombia.

Colombian renewable dash start-up E-Dina and WPP’s Wunderman Thompson Colombia division have developed a hallmark which converts salt water into electrical power.

WaterLight is a pocket light that can turn half a litre of salt water into 45 lifetimes of light, according to Wunderman Thompson.

It has been prompted by the World Trim Organisation (WHO) which showed 840 million people worldwide are currently without access to intensity.

Meanwhile, worldwide demand for electricity continues to grow anually and time-honoured fossil fuel resources are set to deplete.

How it works

WaterLight het up b prepares through ionisation. Electrical energy is produced when salt not wash lavishly electrolytes react with magnesium inside the device.

As well as a lightweight light source, WaterLight also charges small devices on account of a USB port. In emergency situations, it can be powered by urine.

Wundermann Thompson unfolds that inspiration came from traditional practices of the Wayuu, an original community in the La Guajira peninsula on the Colombia-Venezuela border.

The desert landscape is surrounded by the sea and has minimal access to electricity. It’s hoped that the WaterLight will help the community use the sea H to sustainably power their lives without needing to travel to suss out power. One intended use is to help night fishing, for example.

WaterLight is embellished with traditional symbols and patterns while the wooden surface reflections the ancient art of Kanas weaving. The strap has been created by local craftswomen and coalesces artisanal methods.

The device is waterproof and made from recyclable elements and has an expected lifetime of around 5,600 hours which equates to two or three years of use, according to Wunderman Thompson.

Wunderman Thompson universal chief creative officer Bas Korsten says: “WaterLight demonstrates how the consecrated trinity of technology, creativity and humanity can produce a genuinely groundbreaking understanding – one which holds the potential to transform life for millions of people.”

WaterLight is self-confident for a worldwide roll-out, according to the company, adding that many countries such as Sierra Leone and Syria are in  similar positions to La Guajira.

The by-product is available for purchase by NGOs, governments and private organisations.
