260: Saltwater lamp

Problem:

The Philippines ranked third as the most disaster prone country in the whole world. And in disaster situations such as super typhoons, earthquakes, a steady supply of food, drinking water and a sustainable light source is very essential.

Solution:

After living with the natives of the Butbut tribe for days relying only on dangerous kerosene lamps and moonlight to do evening chores, Aisa Mijeno, both a faculty member of Engineering at De La Salle University in Lipa and a member of Greenpeace Philippines, together with her brother Raphael, invented the Sustainable Alterative Lighting (SALt) lamp.


The SALt LED lamp which can be powered by saltwater through metal-air technology is an alternative environment-friendly light source suitable for off-grid in areas near the sea. It uses the science behind the galvanic cell, the basis for battery-making, changing the electrolytes to a non-toxic, saline solution, making the entire process safe and harmless.

The consumables of this lamp only need to be replaced every 6 months. The SALt lamp operates 8 hours a day every day, with proper maintenance, with an anode lifespan of 6 months. For emergencies, the user can charge their smartphone using this lamp, simply by plugging in the USB cable.

In 2017, the SALt lamp went into production It won the Good Design Award 2018 presented by the Japan Institute of Design Promotion, a Japanese comprehensive design evaluation and commendation system. The Mijenos found two partners; one of them is a semi-conductor company located at Laguna Technopark; the other one is San Miguel Yamamura Packaging Corporation.

They are the ones helping SALt with all of their packaging needs: the box it comes in, the plastic, and even the design of the package. Their short-term goal is deploying the first 45,000 units to and beyond the Philippines.

An alternative, the Aria Natural Himalayan Crystal Salt Lamp from Levoite was displayed during the 2017 Consumer Electronic Show (CES) in Las Vegas, Nevada.
