Hydro Power Digital Clock

This eco-friendly clock includes 3 water-powered batteries, each of which consists of two electrodes made of special alloys which, when immersed in water, produce electricity through chemical reaction. Simply refill the battery as the water evaporates--typically every 2 to 3 months. The batteries have a minimum conitinuous lift of 2 years. Note: please allow a few hours for the batteries to work the first time.
