Batteries Not Included

Nearing the end of the first decade of the 21st Century, technology is constantly on the rise. Now scientists have invented a clock that doesn't rely on batteries. Instead the electricity is water generated.

Here's a brief explanation from thinkgeek.com: "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."

JA Bank are giving away free 'eco-clocks' to each new customer. (sorry about the quality, I hope you get the gist)



Here comes the science part:


One clock has an alarm, temperature and timer settings as well depending on which tilt the water sloshes. The nice thing about this next clock is that it can double up as a vase!
