While electricity is essential for solving many development crises around the world, millions of people still lack access to electricity, especially those who live in rural areas. These very same people also receive poor and insufficient supplies from their governments, causing significant implications on their healthcare, food, etc.
This is also a long overdue issue in the Philippines, that’s why three siblings came out with one viable and cost-effective solution. Aisa Mijeno, along with her brothers Ralph Mijeno and Oscar Bryan Magtibay, came up with the idea of creating a lamp that can run on salt and water.
Aisa is a computer engineering graduate and currently a member of the engineering faculty of the De La Salle University in Lipa, Batangas.
Together with her siblings, she invented a lamp that can be generated by a glass of tap water, added with 2 tablespoons of salt. The said lamp can last up to 8 consecutive hours! Not only that, the lamp can also be generated by natural salt water such as sea water. Impressive, right?
They called their invention the SALt or Sustainable Alternative Lighting. It is by far the best alternative for kerosene lamps and candles which are typically used by most Filipinos. Not only is it environment-friendly, it is also safe to use as it isn’t flammable like traditional lamps. Another one of its surprising features is its built-in USB port where you can charge your smartphone!
Even though their invention may affect businesses that offer similar services like those which produce expensive solar panels, Mijeno pointed out that their invention ultimately aims to change the habit of Filipinos living in remote areas such as Kalinga where the invention of the lamp first came to her.
A Greenpeace Philippines member said that the residents in some communities there have to walk for six hours every other day to get kerosene for their lamps. With Mijeno’s invention that utilizes easily accessible ingredients like water and salt, they wouldn’t have to endure walking for long hours and spend much on kerosene anymore. While SALt needs changing of some parts every six months, it would only cost them P100 (USD 1.92) and P200 (USD 3.84) to sustain the lamp up to a year!
Mijeno further explained that they still fully support those who promote the use of renewable energy and have no ill intention whatsoever of competing with other inventors of sustainable alternative light sources.
