Time to go green: the H20 powered alarm clock
Shiny Shiny have picked out this cool little alarm clock that's powered by plain old water and a pinch of salt.
Generating electrical power from water is not as complicated as you might think, so it makes sense to use it in tiny gadgets that would otherwise be taking replacable batteries. The water powered Bedol Wall Wave Clock has electrodes that use the ionization in the water to generate enough current to run the LCD clock. I'm going to omit the part about the pinch of salt - no idea?

That's awesome, now if they could only do it with cars. BTW the salt is to ionize the water, such that it can conduct electricity
