Colombian renewable energy startup E-Dina has presented a solution that promises to improve the quality of life of communities without access to this vital resource, offering an energy alternative with the power to supply a great demand while taking care of the environment.
The startup has developed a wireless lantern called WaterLight, that produces electrical energy from a renewable natural resource such as saltwater.
Developed in collaboration with the Colombian division of creative agency Wunderman Thompson, WaterLight is a more reliable alternative to solar lamps in off-grid communities.
The portable device needs to be filled with 500 milliliters of seawater – or urine in emergency situations – to generate light for 45 days.
This, thanks to the ionization of an electrolyte composed of saltwater, which reacts with magnesium and copper plates on the interior of the lamp to produce electricity.
The WaterLight acts as a mini power generator and can be used to charge mobile and electronic devices via a USB port. It will also help fishermen to fish at night and will allow craftsmen to sell a higher amount of orders by allowing them to work at night.
WaterLight works 24 hours a day through ionization, which allows the lantern to produce electricity, and light, for long periods of time, thanks to E-Dina’s patented way to sustain the chemical reaction over a prolonged period of time.
WaterLight has been created as a 100% recyclable and durable product. It is designed to run for 5,600 hours – which equates to more than 230 days or 2 to 3 years of use, depending on how often it is needed.
