Filipino Entrepreneur Creates Revolutionary Lamp That Runs on Saltwater

Meet Aisa Mijeno, a Filipino architect and scientist who invented a revolutionary lamp that runs on a glass of saltwater instead of batteries. Her vision in creating the SALt (Sustainable Alternative Lighting) lamp was to “light up the rest of the Philippines sustainably,” by finding an environment-friendly alternative light source suitable for people in coastal areas. She came up with the idea after spending time with the locals of the Butbut tribe in the Kalinga Province of Philippines, who had no access to electricity.  

The lamp can apparently run for eight hours on just two tablespoons of salt and a glass of water. “It is made of tediously experimented and improved chemical compounds, catalysts, and metal alloys that when submerged in electrolytes will generate electricity,” Mijeno explained. The idea behind it is the chemical conversion of energy, but while it works on the scientific principle of the galvanic cell, it makes use of a harmless, non-toxic saline solution instead of hazardous electrolytes.
