first_imgEver since the earthquake and subsequent Fukushima nuclear disaster that occurred in Japan last year technology has been developed to help if such an event were ever to occur again. One of the biggest problems to overcome in Japan was a lack of power, which has led one Japanese company to create a light that runs purely on salt water.Green House Co. Ltd. has developed the LED Lantern (GH-LED 10WBW), which contains no battery, instead replacing it with a water bag. A mix of 350 milliliters of water and 16 grams of salt allow the lantern to act as a light source for up to 8 hours. After that, you just refill the bag for another 8 hours of light.The LED Lantern functions by using the salt water as an electrolyte. Once placed inside the lantern the solution works with magnesium and carbon rods to produce the necessary power for the light. The magnesium rod also needs replacing, but works for at least 120 hours and replacing it with a new rod is thought to be a simple task.The luminous power of the light is rated at 55 lumen, but the lantern isn’t just limited to acting as a light source. On its casing you will find a USB port, allowing you to plug in and charge other devices. So if you are stuck in a power outage at night you can use the LED Lantern to light the way while it charges your smartphone.Green House is expected to release the LED Lantern before the end of September in Japan. The one thing not yet know is the price, but due to the limited parts it uses I can’t see this being a very expensive device, but it’s certainly one lots of Japanese households will want to have ready in a cupboard just in casevia Tech-On!last_img
