Small communities in the Philippines will soon be using salt water-powered lamps, instead of candles. The Sustainable Alternative Lighting project, also known as SALt, has gifted the nation of 7,000 islands with this innovative gadget. It uses a solution of one glass of water mixed with two tablespoons of salt, or just salt water from the sea, to provide 8-hours of continuous light. The electrode inside can be used for up to a year, depending on how often it’s turned on. Continue reading for more pictures and information.
“The energy comes from one of the electrodes, which is eventually spent, like a log on a fire will eventually be spent. Mijeno’s says his SALt lamp will run for eight hours per day for six months before you need to replace the anode, and that to run it for those eight hours you just need a glass of water and two teaspoons of salt. There’s even a USB port on the side to charge a cell phone or what have you,” reports Fast Company.
