A SALt lamp is an LED lamp powered by the galvanic reaction of an anode with saline water. It also has a USB port to charge low-power mobile devices such as cellphones, smartphones, and mp3 players. The anode must be replaced approximately every six months and the saline water daily; sea water is usable. The SALt lamp was invented and is marketed by Aisa Mijeno, a Filipino inventor and entrepreneur. She is also a faculty member of Engineering at De La Salle University — Lipa, and a member of Greenpeace Philippines. The product concept was formed after living with the natives of the Butbut tribe for days relying only on kerosene lamps and moonlight to do evening chores.
