Green Design: Water-Powered Alarm Clock

Don't let that alarm battery run out ever again! This water-powered option will keep on ticking.

Have you ever forgotten to replace the batteries in your alarm clock but realized it only after you overslept for an important meeting?

That will never happen again with this water-powered alarm clock, available from Bedol. The eco-friendly design keeps the time and wakes you up just like a regular, battery-powered alarm clock. The only difference? This one is powered by water.

I suppose that using water to create power isn't anything new, but on average, most of us don't use water power for our small appliances or electronics. According to Bedol, some of their customers report that it is necessary to change water after 6-12 weeks, but for others it just "keeps on ticking." And when you're refilling the water, the clock even remembers the time, so not a second is lost.

The clock is $29 at Bedol's and comes in five colors. The Claremont, a California-based company, also makes water-powered non-alarm clocks for $16. I think that's small change to pay knowing you're saving money and the environment by not using batteries.

So does it really work? Well, it's hit or miss according to Amazon reviewers who purchased the non-alarm clock. I guess it's just one of those products you have to try for yourself.
