Powering Lamps with Salt Water
Most villages in developing countries have no access to electricity. People have to rely on kerosene/battery powered lamps as their main source of lighting which is not sustainable. To tackle this issue, Sustainable Alternative Lighting (SALt), have come up with a cost effective ecologically designed lamp powered by tap water and table salt!
The core competency of their lamps are:
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.
2. Environment Friendly
In disaster situations such as typhoons, massive landslides, and 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.
3. Ease of Use
You can even use 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.
With proper maintenance, their SALt lamp will give you an anode lifespan of 6 months if used for 8 hours every day. How else can we tap into readily available resources to come up with similar innovative solutions?
