Salt water lamp a “social movement”

August 5, 2015

A start-up team known as Sustainable Alternative Lighting, or SALt Corp, based in the Philippines, has invented an environmentally safe lamp that runs on salt water.

According to an article in, the lamp only needs two tablespoons of salt and a glass of water to work. It uses “the science behind the Galvanic cell, the basis for battery-making.” It changes electrolytes to a saline solution, in “an approach that is nontoxic, and avoids the tragic incidents of fires that are caused by candles and tipped over lamps.”

The designers call the lamp a “social movement” as well as a product. They hope to target the lamp to the many communities who live without utility power in the Philippines. In a country of over 7,000 islands they have ample access to ocean salt water.

Aisa Mijeno, a faculty member of engineering at De La Salle University in Manila, is co-founder and chief executive officer of SALt Corp. They hope to start producing the lamp by the end of this year.
