This amazing little lamp runs entirely on saltwater! It’s called the SALt Lamp and it was founded by a company located in the Philippines. This nifty invention can run for 8 hours on just 1 glass of water and 2 tablespoons of salt. That’s all you need!
The SALt lamp does not use any complicated technology or harsh toxic chemicals either. Just simply add the water and salt and you’re good to go. The company’s website (at http://www.salt.ph/) states that the SALt Lamp can also run on pure seawater! This would place this new technology in a position to really scale and, perhaps some day soon, power small towns or cities, especially in the coastal regions where saltwater is prominent.
The company’s website states that the salinity of ocean-water will operate the lamp. You can 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”
Another cool thing about this lamp is that it will also charge your cellphone or other small USB device with a simple USB charging cord. The SALt lamp uses the science behind what’s called a “Galvanic” cell, the basis for battery-making, changing the electrolytes to a non-toxic, saline solution — making the entire process safe and harmless.
Using the SALt lamp for 8 hours a day every day will give you an anode lifespan of about 6 months.
