Sounds like a gimmick, but it’s surprisingly innovative. Using “state of the art technology,” the H2O Water Powered Can Clock ignites an electronic charge to power a hi-contrast LCD clock, which runs for a long time period. Using positive and negative electrodes, the clock’s patented technology utilizes water to “create an electrochemical reaction,” generating electrical energy that keeps the clock running. It’s measured at 11cm x 5.8cm (4.3in. x 2.3in.) and it’s crystal-clear frame allows owners to see the electrodes handle there business. Water replacements are in order, due to evaporation, but only requires a refill every 6 to 12 months, and the battery life of the clock lasts about 2 years.
