The H2O Water Powered Can Shaped Clock uses state of the art water technology to power a large hi contrast display (LCD) clock. This clock will run continuously for a long time without needing any human intervention.
By using positive and negative electrodes (in a similar way to the potato clocks of old, yet more attractive) the H2O Water Powered Can Clocks patented technology creates an electrochemical reaction with water, thus producing the electrical energy for powering the LCD clock display. The Can clock is the size and shape of a conventional can of drink, roughly 11cm x 5.8cm (4.3in. x 2.3in.), its coloured transparent body allowing you to see the electrodes within.
The water will need replacing due to evaporation. The evaporation though should be at a slow rate as the water is well encased, meaning it will only require a water top up every 6 to 12 months.
The battery for the H2O Water Powered Can Shaped Clock does have a minimum continuous life of 2 years, though by simply allowing the device to fully dry out when no longer required you will elongate its years of usage, as it will be ready to go again as soon as the can shaped clock is once again full of water.
