No batteries or regular electricity for this nifty eco gadget! Green House's Salt Water LED Lantern doesn't need power in the old conventional way, instead using salt water and a special power rode to give 55 lumens of illumination thanks to 10 LED lights.
The lamp is really just powered by 350 cc of salty water, which you only need to replenish every eight hours. The science is not only super clever (combining two electrodes, a magnesium rode [-] and carbon rod [+]) but also super ecologically friendly too, and great for emergencies when regular batteries or power supplies may not be to hand.
Its handle makes it very practical and mobile, as does its light weight and included USB cable to easily power your own devices. Even sea water is okay -- meaning this is the ideal lamp for taking on vacation!
