The Bedol Water Clock, created by Mark Bedol, doesn't need electricity or batteries to keep time. Instead, it derives electricity from the ions naturally found in plain old water. Simply pour water into the cells behind the clock and it will run for the next 6-12 weeks. It’s shaped as a water drop and comes in blueberry blue, kiwi green, tangerine orange, plum purple, and smoke gray. We’re not sure alarm clocks have that big a carbon footprint to start with, but it’s a cute gift idea for your green friends. Available for B1,166, order online at
