I was wondering if anyone out there might be able to tell me how these water clocks work. All you do is fill it up with mildly salty water, and that's what it runs on. The one I've got has been keeping good time for about 5-6 days now. Once in a while a little bubble comes up, so it must be producing some kind of waste gas. I'd like to build my own circut based on whatever devices run this clock, just for fun. Would anyone know what kind of electronics run on water? And where I could get them? I didn't buy my clock through the net, but it's selling at: http://www.computergear.com/waterclock.html All the site says about how it runs is: "The fuel cell extracts electrons from the electrolyte forming a steady stream of electrical current that drives the clock." That's all very well, but it doesn't tell me what the name of the fuel cell is, where I can get them, and how I can build a curcit based on the fuel cell's power.
The project you describe is here (though it uses lemon's instead of salt water its the same idea):

And there is even an official "Lemon Power Website" (the Internet has everything doesn't it?):
