MAXELL MIZUSION SALT WATER LAMP
This LED light doesn’t use batteries or solar panels to power it, but rather salt and water. The Mizusion lamp (‘mizusion’ is Japanese for salt and water) contains a magnesium cell, or power bar, that creates electrical current when in contact with salt and water – even seawater will generate electricity. Each power bar provides 2 000 Lux of light for about 80 hours and “can be replaced at a nominal cost”. The lamp itself is expected to last 10 years. Developed in Japan by Hitachi, the Mizusion LED salt water-powered lamps will be available in most outdoor equipment stores in SA soon.
