A clock that runs on water

This is like magic. A clock that runs entirely on water – no batteries, no chords, no windings. The Bedol Water Clock is the most environment friendly clock that runs 100% on natural power. Simply fill the container with water and a little lemon juice and you’re set for 6 to 8 weeks of timekeeping before refreshing. An in-built memory chip ensures you don’t lose time even while changing water.

How does it work? According to ThinkGeek.com, 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.

The Bedol Water Clock is inexpensive at $16 and comes in 4 different colors.
