Admittedly, Hydro Power is probably the wrong name for this clock.

How it works: Water-powered battery consists of two electrodes made of special alloys, which, when immersed in water, produce electricity through a chemical reaction.

Simply refill the battery as the water evaporates - typically every 2-3 months. The battery has a minimum continuous lift of 2 years.

Just add water and the clock is ready to go! Free energy at work.
