What could be greener than just using a little tap water to power your alarm clock? This cool clock makes its own electricity from its electrolytic cells and the water electrons. One refill should power the clock for about 12 weeks, then all you need to do is fill it up again. It will remember the time so you don’t need to re-set it after each refill. The ergonomic design looks modern and svelte – it’s bigger than it looks in the picture though, at 6 ½ “ high. There is a choice of blue or gray. And you’ll have one less gadget to reset after a power outage too!
