It's a total lie to call this thing "water powered", as the water is simply the electrolyte for a weak primary battery. The metal electrodes slowly being corroded by the water are the real source of energy. Given enough time, they would eventually be used up.

There's nothing wrong with powering a clock this interesting way, but calling it "green" or "alternative energy" or eco-anything is a complete misrepresentation. It's an old-fashioned wet cell battery, plain and simple.

Water clocks are powered by small fuel cells which use water as an electrolyte from which to extract electrons. The description is incorrect when it says the clock does not use electricity. Of course it uses electricity. Nothing but electricity is going to make an LCD work. So, it's a clock with a rather unconventional battery. In some ways, it is sort of like unsealed car batteries that require the addition of water at intervals.

2-3/5 review. Good idea but not good for alarm clock. Why not combine both water and backup battery (for alarm clock and night light, but keep daily running using water).

Cool article on how water powered clocks work, both historically and modern ones. The way THIS one works is on page 3 of the article.
