Most of the clocks we see hanging on the walls of homes and offices today are battery powered. There are a few that might be powered by a spring or wired into the room’s electricity. However, battery or electric power aren’t the only ways to operate a clock.
A company called Bedol has a whole range of clocks that are powered by water. The latest clock from the company is a wall clock that is powered by H2O. The clock is shaped like a drop of water and has a translucent tank in the back. The water put into the clock interacts with metal plates in the tank to produce electricity.
One tank full of water will power the clock for six months to a year according to its maker. The clock then needs to be refilled and it will continue telling time. The Water Wall Clock comes in several colors, and sells for $89(USD). It will start shipping this April.
