If your house is in an older neighbourhood like mine, you’re intimately familiar with the summertime power outage game, and you probably also own stock in at least one battery manufacturing company. But you probably also want to be more environmentally friendly, and while a clock really doesn’t use that much power, it is something that should be easily taken off the grid. Now it can be!

The Bedol Water Clock runs on tap water, and you don’t even need to change the water for three months! All you do is twist off the base and fill it with water, and electrodes within the reservoir convert ions into current to power the clock. It features a built-in memory chip so you don’t have to reset the clock when you do have to change the water, which is a definite advantage over battery-powered clocks. The clock comes in blue, green, purple, pink and charcoal, so it can fit into practically any room’s decor. Additional features include a daily or hourly alarm and an easy to set 12-hour or 24-hour time setting.

I can’t think of a better way to decrease my carbon footprint while also never being stuck without an alarm clock and not having to worry about having no electricity or being out of batteries. If you agree, you can pick one up for just under $30.00 US.
