Gadget of the Week – SALt (Sustainable Alternative Lighting)

Published on August 19, 2015

We're always on the hunt for technology that promotes green living, and this latest invention brings its A game to the green team.

SALt - short for Sustainable Alternative Lighting - is a lamp powered by tap water and table salt.

And thats it.

The beauty of this lamp is in the ecological simplicity of its power. 1 glass of water and 2 tablespoons of salt power this lamp for 8 hours. No outlets, no batteries, and no sunlight required. Using the SALt lamp for 8 hours a day, every day, will give you a 6 month anode lifespan before that component needs to be replaced, while more moderate use will get users up to a year of use before replacement is needed.

Smartphones too can be charged through the energy of this lamp.

This lamp has been designed specifically with the Philippines in mind, as an alternative way to provide sustainable, environmentally safe lighting at low cost. These lamps are also intended for use in disaster situations where power and light may be hard to come by.
