Water. Salt. Light.
Born in the Philippines, this new engineering project was designed as a sustainable lighting source for areas that don't have access to electricity. Instead, populations in these regions use kerosene lamps or candles wich are dangerous and produce a low amount of energy.
SALt (Sustainable Alternative Lightning) might be the answer to many of Philippines 7.000 islands energy access problems, but its usage can be extended to other parts of the world. At a glance, SALt looks like another battery-powered lamp, but The SALt LED lamp relies on a galvanic cell battery, in which the electrolyte solution consists purely of salty water, into which two electrodes are placed.
There are no materials and components inside the lamp that may cause fire accidents. One less thing to worry about for families that rely on kerosene lamps as their main source of lighting. This lamp 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.
According to a study conducted by the United Nations, The Philippines ranked 3rd 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 sustainable light source is very essential. The importance of the product in terms of short term usability and as a long term household staple can be attributed to how easy and common the elements needed to power the lamps are. It also does not emit harmful gasses and leaves minimal carbon footprint making it very environmentally friendly.
Do you live near the ocean? The salinity of ocean-water can operate your lamp. Use the ocean-water to power up your lamp and it will give you 8 hours of running-time. Salinity is expressed by the amount of salt found in 1,000 grams of water. The average ocean salinity is 35 parts per thousand. Store ocean-water in bottles and use them to power up you lamp anytime, anywhere.
The SALt project has received several prizes in the Phillipines, Singapure, South Korea and Japan. Although the design of SALt is being developed for some time, the product is not yet available for purchase. Its developers are receiving pre-orders and the lamps will be shipped as soon as possible. According to the team behind the idea, the first SALt LED lamps might be available by late 2015 or during the first quarter of 2016. However, priority is to build lamps for target communities and for the communities of the NGOs and foundations who will partner with the project.
