This cool new Mizusion Saltwater-Powered LED Lantern from Japan is an innovative LED lantern that doesn't use batteries, it uses nothing more than salt and water to provide up to 2,000 lux illumination for up to 80 hours. Just pour the water and salt into the top and it's ready to shine. A great alternative lighting source to keep on hand in case of emergencies, power outages, worldwide floods, or just any apocalypse where water and salt will still be hopefully around and fresh batteries aren't.
