WattBlocks

There are devices in our home that are famous for using energy even when they're not being

put to good use. Inventors in the Greener gadgets competition have fortunately come up with an

idea to stop wasting this energy and even put money back in your pocket that you shouldn't be 

spending on the energy that is being used in idle times. "WattBlocks" is the device that has been

created to easily stop this problem. The product is designed so that with a tap of your foot, it will

disconnect devices in your home that are using standby power. It's been estimated that this standby power accounts for $100 of a home's yearly power cost adding up to $10 billion annually in the United States.

The device is consisted of several WattBlocks, which are plugged in between wall outlets and vampire devices, and a master step switch that plugs into an outlet near the entry/exit of the home. As the user exits, tapping the step switch sends a signal through the home's power lines, telling all WattBlocks to block power to the vampires. The benefits are significant, with potential savings of up to 20,000 Watt-hours every month.
