Forget kerosene. This lamp runs off salt water

Philippines – It all started with the idea of illuminating the darkest communities in the Philippines using a staple commodity. 

In 2011, during an immersion trip with a local tribe in the northern province of Kalinga, Aisa Mijeno came up with the idea for the Sustainable Alternative Lighting, or Salt, lamp.

“I learned that people don’t have access to electricity and use kerosene lanterns as their main source of lighting,” she says, adding that the local people had to go down the mountains every other day to buy kerosene for their lamps. 

“This inspired me to come up with Salt lamp, since salt is pretty much abundant and a staple item in every household in the Philippines,” she recalls. 

More than four years later, during the Asia Pacific Economic Cooperation summit in Manila in November 2015, Mijeno shared the stage with US President Barack Obama and Chinese business magnate Jack Ma to discuss the project. 

“I was really nervous. I knew that I was there to represent the local startup community and later realised that it was not just the local startup community but the Philippines as a whole so I thought I should be really careful with all my answers,” she recalls.

She said the invitation to join Obama and Ma – the founder and chief executive officer of Alibaba – came as a surprise. Mijeno, her brother and Salt co-founder Raphael, and the rest of their team were supposed to join the summit for small and medium enterprises. 

While on their way, she said she received a call from someone from the White House inviting her to be part of a panel discussion that would be moderated by Obama. 

“The first emotion I felt, to be quite honest, during the whole conversation was fear – because I was not sure if we were ready for the kind of exposure this will bring us. It will surely put a heavy pressure on our shoulders, but it was a once in a lifetime event, so my brother pushed me to accept the proposal,” says Mijeno. 

During the discussion, she explained the concept of Salt, which uses a saline solution to power LED lamps and a USB port that can charge smartphones. 

She evoked to the audience, “the huge effect we’ll be able to contribute when we dive into developing large-scale for the technology”. 

“Just imagine if we are able to power a whole island using ocean water.” 

Obama, who led the panel discussion after his speech at the summit, was impressed with the presentation of the young engineer, entrepreneur, and part-time faculty member at the De La Salle University in Lipa, Batangas. 

“I think Aisa is a perfect example of what we’re seeing in a lot of countries, young entrepreneurs coming up with leap-frog technology,” he said.

This lamp won’t only bring light to rural communities, but will also help them deviate from the use of kerosene. 

“Kerosene lanterns have been so pervasive because this lighting system has been passed down from generation to generation. But instead of pouring kerosene, you’re pouring saltwater. Instead of lighting a match, you push an on and off button,” she explains. 

The lamp uses the science behind the “Galvanic cell”, which is the basis for battery-making. But instead of electrolytes, it uses a non-toxic saline solution to make the entire process safe and harmless. 

Mijeno says they are continuously developing the design and the system to make it even more efficient. 

“We are working on new units to be deployed still for field testing. We wanted to extract all needed inputs for design, system, and functionality so we can improve the product even more before really going into mass production,” says Mijeno. 

“But we are also working towards the production of a first batch for distribution. Currently, we are in partnership with a local manufacturing company and working together with their engineers,” she adds. 

The startup also started various social activities with the aim of providing lamps to communities with no access to electricity. Among those identified as beneficiaries are residents of Buscalan town in Kalinga, where everything began. 

“[We plan to] focus on research and development and further create more efficient innovations that would help uplift people at the bottom of the pyramid,” she says.
