WaterLight is an Eco Friendly Lantern Powered by Saltwater
Many islands, villages, and tribes across the world still lack access to electricity. After the sun goes down, light is usually emitted from kerosene lamps. Despite being cheap, it can cause fire hazards that are bad for the environment and human health. Created as a viable solution to this problem, WaterLight is an environmentally-friendly saltwater lantern.
The handy device WaterLight provides electric power using saltwater, thanks to the ionization of an electrolyte that transforms the magnesium in saltwater into electrical energy. The design is inspired by the Colombian Wayuu community and ancestral connection with the sea.
The ingenious solution assures to last up to 45 days with just a half-liter of saltwater. It is portable and can be used whenever and wherever. Interestingly because the process separates salt from the water, the water in the device can be consumed after the power runs down.
The device can be used for two to three years and then can be recycled. The lantern can also slowly charge mobile phones and simple devices. Unlike solar lamps, it charges instantly after being filled with water.
According to Pipe Ruiz, an executive creative director for Wunderman Thompson, millions of people around the world are without access to electricity in the coastal areas and it is imperative to provide them electricity through affordable and environmentally-friendly means.
Children can now use the light to study, Craftsmen can get enough light for work. In Guajira Peninsula, members of the Wayuu tribe tested the device to test if they can fish at night. The catch is that they are expensive but millions of people can access light without electricity.
