While we wait with fishy breath for cars that run on water, we'll have to settle for something smaller (but nearly as cool) - this digital clock uses no batteries, no cord, just two tiny cups of water connected to its back. Keep these two cups full of that cheap stuff that streams from your tap and this clock has all the electrical power it needs to display the full time and date.

The Water Powered Clock ($12.99) is truly environmentally friendly, and a great novelty item to boot. 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.

So how does it work? Well, 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. Blooming ingenious!
