Despite progress on global energy targets, according to several global organizations, it is estimated that 840 million people are currently without access to electricity, hindering their ability to work beyond daylight hours, carry out essential tasks and stay connected to the wider world. With electricity demand expected to increase by 70% by 2035, and traditional fossil fuels estimated to be depleted in the next 52 years.

The goal was to create a device that can offer a free clean energy option to developing countries without access to electricity.

WaterLight, is a device that provides 45 days of light using only salt-water.

This device, is also capable of charging small appliances such as a cell phone or a radio via a USB port. Perfectly suited to seawater, the device also responds to fresh water mixed with salt and even – in emergency situations – urine.

The Wayúu’s cultural heritage is further reflected in the waterproof design. Decorated with traditional patterns of power, the wooden surface draws inspiration from the ancient art of ‘Kanas’ weaving, with stylised geometric figures representing the sea, fauna and flora of the natural environment. Meanwhile the strap, created by a ‘Eünün’ – the craftswomen of the community – stays faithful to its artisan roots.

WaterLight has been created as a long-lasting, 100% recyclable product. Designed to function for 5,600 hours – which equates to over 230 days or 2 to 3 years of use.

World Health Organization reports that 840 million people are currently without access to electricity, hindering their ability to work beyond daylight hours, carry out essential tasks and stay connected to the wider world.

Insight: Governments, NGOs and private organizations around the world should be interested in seeking sustainable technology solutions for their specific coastal communities.

Key message: Clean energy innovation set to light up communities lacking electricity across the world.

Target audience: Governments, NGOs and private organizations.

In creating this forward-facing technology, E-Dina Colombia looked to the age-old traditions of the Wayúu, an indigenous community living on the remote La Guajira peninsula straddling the Colombian-Venezuela border. Although access to electricity is limited, the arid desert terrain is surrounded by the most powerful battery in the world: the sea. With the help of WaterLight, the Wayúu will transform an abundant natural resource into a safe, sustainable way to power their lives, from night fishing to charging mobile phones without the need to travel for miles, creating a sense of connection within the community and to the wider world.
