Some students of Philippines are generating 8 hours of
electricity from 1 glass of ‘Salt Water’
We live in an era of accelerated progress where technology forms the backbone for a well functioning community and tries to answer the most of the problems which exist in the present world. It delves innumerable aspects of this universe and one such illuminating aspect is light. Light, which helps us to see and live the way we are living. Have you ever thought what if someday it gets snatched from us? What if we were still living in the dark? What if all the time we had to do something was before dusk? What if there was nothing but darkness all around? Well even today there are places where many communities are not connected with the power grid. Here, life passes very slowly, and people still survive using extremely old methods of sustenance. They face problems which threaten their livelihood and existence. Men are forced to walk miles just to buy kerosene from their neighbouring towns to make themselves even capable of seeing each other.
To find a solution for the problem which poses a monumental hurdle to survival in their native country of Philippines a team of brother and sister Aisa and Raphael Mijeno provided the rural communities a safe and cost effective light source with the help of basic amenities found in one’s home water and salt. They combined and used a handheld bulb which was charged for eight hours by a glass of water and two tablespoons salt. It was modelled after the Galvanic cell battery but with the electrolyte as a non toxic saline solution unlike other designs. The two different metals submerged in water, reacted and provided excess electrons which created current and supplied power to lead. Beyond initial costs, the metal anode will require replacement every six months if the lamp is used eight hours a day. Due to the usage of Salt, the lamp and its components will be more cost-effective than kerosene or a battery-powered lamp, as the fuel is free. This how they created an innovation so imperative and substantial whose importance in today’s world cannot be described on papers.
As they scale their business to meet demand, their aim is to produce for partner organizations – non-profits, foundations and local governments who will purchase and distribute the lamps – and hand-picked communities, with lamps provided by retail sales. The potential for the salt lamps extends far beyond the Philippines. According to the International Energy Agency (IAE), billions of people live without electricity. Not included in this statistic are all those who face regular blackouts, or the natural and man-made disasters that necessitate emergency lighting. Aisa and Raphael are the torch lighters to such detached rural communities and have showed how even the most powerful energy can be produced out of the minute and the cheapest materials such that it can be accessible to all.
An absolute example of intelligence personified. We hope that more simple, innovative and cost effective come into the limelight and touches millions of lives and changes the lives of millions others.
