In Canada, most of us enjoy a rather privileged life. Take the simple amenity of lighting, for example. An average Canadian home will be outfitted from top to bottom with an electrically-powered lighting system, providing residents with adequate light with but a flip of a switch.
Communities in other nations aren’t quite so lucky.
To citizens of certain countries, technological sources of light are something of a luxury. Take the Philippines, for example, a nation where a vast amount of peoples rely solely on kerosene-fuelled lamps to provide light after dark.
Not only something of an outdated technology to the Western world, kerosene lamps also bring about certain risks. For one, to the Filipino people who rely on kerosene lamps, obtaining fuel can be a rather long trek. Secondly, kerosene itself can result in adverse health effects simply by exposure.
Unfortunately, kerosene lamps are seen as a necessity for communities found across the 7000 islands that make up the Philippines, where electricity is largely unavailable. That conception will soon change with the dawn of the Sustainable Alternative Lighting (SALt) lamp, a light source that is entirely powered by salt water.
Created by sibling engineers/entrepreneurs Aisa and Raphael Mijeno, the SALt lamp was designed and created to solve the issue of the widespread use of kerosene lamps in the Philippines. Powered via a saline solution, or simple salt water from an actual body of water, the SALt lamp removes the need for kerosene entirely, replacing it with a natural resource that is in abundance for island-based Filipino communities.
The science behind the SALt lamp is pretty simple in itself, too. Utilizing the Galvanic cell process, the SALt lamp simply substitutes electrolytes with a saline solution/salt water to create energy. The SALt lamp system is able to power an LED light and is even outfitted with a USB port for charging devices like a smartphone.
Revolutionary in itself, the SALt lamp technology can become even more groundbreaking if/when it is expanded. The Mijenos hope the salt-water-powered technology will be able to provide energy for a whole island, thus providing light and electricity across the Philippines.
