A Lamp That Runs on a Glass of Water SALt
A Philippines based company has developed a lamp that can run for eight hours at a stretch on a glass of water and two tablespoons of salt . The Sustainable Alternative Lightning ( SALt ) lamp does not have any hazardous material or component and it has a USB port for charging a smartphone.
According to SALt website, “ Three are more than 7000 islands in Philippines and most of these do not have access to electricity. We want to eliminate the sustaining cost in areas that rely on kerosene/battery-powered lamps and candles as their main source of lighting.”
The lamp uses the science behind the galvanic cell, the basis for battery-making changing the electrolytes to a non-toxic , saline solution, hence making the entire process safe and harmless.
When electrodes are placed in the electrolyte, the energy generated kicks an LED light into gear. Moreover the salinity of ocean water can operate the lamp.
