Bedol H2o Run Clock Blue
The Bedol H2o Clock keeps perfect time without batteries or electricity. Just open the fill cap and add h2o. Cutting-edge technology permits the amazing Bedol H2o Clock to generate it own clean energy. Electrodes within the h2o reservoir transform ions into a current strong enough to power the clock for 3-month or more. A built in memory chip ensures you never need to reset the time while changing the h2o. Hassle-free alternative energy makes this clock a great green reward. A fool-proof, fun way to decrease your carbon footprint.
