Fast Company contributor Charlie Sorrel takes a look at an innovative new lamp by designer Aisa Mijeno that was conceptualized as a safe lighting solution for parts of the world, like the Philippines, that aren't hooked up to a power grid-- and therefore, rely on relatively dangerous sources such as kerosene lamps.

SALt, or Sustainable Alternative Living, re-purposes seawater as an electrolyte in the same way electrode rods in a car are dipped into electrolyte solution. As the electrode rods are made up of different metals, each one produces a different reaction to the electrolyte and results in one giving up its electrons and one collecting them.

The cycle ultimately produces an electrical current, so users can create a light source by simply adding a bulb into the mix.

"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."
