Water Powered Alarm Clock

Eco-gadgets intrigue us here at FROG and we recently came across this alarm clock that uses water (vital to all amphibians!) to power it. A most unusual alternative energy source that we have an abundance of (both salt and fresh water combined). There are a few different water-powered alarm clocks that sell on various sites, but this one below seemed most aesthetically pleasing to our eyes.

ThinkGeek has this to say about it:

The water clock will display the time and date in clear easy to read numbers just moments after you fill the liquid reservoirs in the back with the liquid of your choice. We’ve had ours running for weeks so far and the water levels have barely descended and we haven’t had to refill it at all.

How does it work? Magic mostly. And a little bit of science too. The internal converter simply extracts electrons from water (or other liquid) molecules and provides a steady stream of electrical current acting as a fuel cell to generate power to the clock. Click here to read full description.

For light-weight electronics, this seems like a fairly viable energy source. If we combine solar and water for powering small electronics, just think where it can head in the future with larger ones.
