Developed by startup Sustainable Alternative Lighting (SALt Corp.), the lamp requires two tablespoons of salt and a glass of water to work and is seen as a main lighting source alternative to kerosene and battery-powered lamps, or even candles. It can also be used to charge smartphones via a USB port.

The lamp is seen as being potentially especially useful in coastal communities with easy access to sea water, which can be used to operate the lamp. It was inspired by a visit to a tribe in the Philippines by SALt co-founder and CEO Aisa Mijeno, currently a faculty member of Engineering at De La Salle University – Lipa, who formed the idea after observing tribe members perform evening chores with only kerosene lamps and moonlight to rely on.

The lamp is based on the Galvanic cell approach, using a non-toxic saline solution for the electrolytes instead of the chemicals typically used in batteries. Used eight hours a day, and with the saline solution refreshed daily, the lamp will last six months according to the company, at which time its metal electrodes will need to be replaced.

The company’s goal is to bring the lamps to market late this year or in early 2016. Although no price has been announced, the company says it is targeting "an affordable price that can also support and sustain the flow of [its] production.”
