Saltwater-powered LED light from Japan

Can you light up a bulb with water?

Apparently you can. It's ingenuity at its best when the Japanese added salt to water and voila! You have simple and cost effective solution to power up your tent, camp, or use it as emergency light during the frequent SESB power interruption.
At RM248 a piece, it's a bit steep but imagine the convenience and its low operating cost.

Green House Salt Water Powered LED Lantern

Green House Co., a Japanese office equipment manufacturer, has launched sales of an LED lantern, its GH-LED10WBW model, which can generate electricity using just water and salt. The device requires no dry cells or battery charging. By simply pouring saline water into the lantern, ions start traveling from a metal rod of magnesium to a carbon rod, thus generating electricity to power the light, which has a luminous flux of 55 lumens.

While the single magnesium rod can generate up to 120 hours of light, the saline water needs to be replaced every eight hours of use. The electricity generated can also be used for USB-powered devices using a USB cable that comes with the lantern. With no need to worry about self-discharging, the lantern is ideally suited as part of any outdoor or emergency preparedness kit.

This can be introduce to our local market. The price is reasonable too.

55 lumen is not that bright (just about less than the brightness of a 20W bulb).
But it should be good for camping, emergency light, etc

Magnesium rod still need to be replaced every 10 to 15 days. How much is each rod? This could be an expensive affair.
