The Water Powered Clock

Requiring no batteries or AC plug, this is the alarm clock powered entirely by water. The reservoir holds 28 oz. of tap water and its internal electrolytic “engine” converts the water’s electrons into an electrical current that powers the clock for up to 12 weeks. A fresh watering of the clock continues operation–an internal memory chip retains the clock’s time during a refill so resetting the time isn’t necessary.
