Here is a little interesting device I thought we should showcase: A Water Powered Clock. There is no rhyme or reason why it is posted on the site. It’s not that cool, it wouldn’t look good in any part of your home or office, heck – it looks like something you bought at the dollar store. One of the primary reasons I wanted to feature the clock is probably because it is so ironic. It boasts about running off of simple H20. But the device uses the water in partnership of a zinc electrode, which corrodes. Meaning once the “battery” dissolves away you have to toss it in the garbage and buy a new one (that’s not too friendly for the environment).
