Innovation is always welcome, even if it be a wee tiny step in the direction. Allow that to be our reason for finding this LED Lantern interesting. For its power source, the lantern requires 350cc of salt water with a 3-5% salinity. Obtaining that shouldn’t be a problem on most of our planet. This salt water serves as an electrolyte, in place of normal batteries and works with two electrodes that generate enough electricity to power the 10 LEDs on the lamp for about 8 hours.
