The new H2O Clock is the latest thing in ecological and environmental design. In itself the clock is not all that amazing but the technology itself is amazing. This multifunctional clock runs on everyday water with the use of a new H20 replaceable battery.
The patented battery works by placing one positive and one negative special alloy at each end of the battery. The result when submersed in water is an electrochemical reaction that results in electrical energy.
The clock itself is an old school style digital display with a twist. Simply rotate the clock 90 degrees and the clock will switch from Time, to Alarm, to Temperature, to Countdown timer.
