SALt, the lamp that works with water and salt

Nov 06, 2015 | written by:

In everyday life we take for granted many things including electricity. However it is important to know that, according to the World Bank and the International Energy Agency, more than a billion people worldwide live without access to electricity.

In the Philippines, this problem is still a reality and, in this land, the brothers Aisa and Raphael Mijeno have developed the idea of SALt (Sustainable Alternatives Lighting), the first lamp that works only with a glass of water and a few teaspoons of salt. The device, designed for the countries where electricity is a luxury, is based on a system that exploits the ability of the galvanic cell to convert chemical energy (the electrodes of a battery react with the ions of the salt) into electrical energy. The economical, safe and reliable process provides about eight hours of illumination and nearly no maintenance.

The device, in addition to shed light, allows you to charge smartphone and mobile phones through a usb port. The first functional prototypes of eco-lamp should be distributed, in cooperation with nonprofit organizations, in the Philippines' rural communities by the end of the year.
