PowerZoa Would Be a Great Answer to the Question: "Did I Leave the Stove on?"S

Why? Because you could use the device to remotely cut power to any gadget that is plugged in to an outlet.

It's only a prototype at the moment (one of many that have come out lately focused on saving energy), which probably explains why it still looks like a child's toy. Not a good idea when you consider that it sits between the wall outlet and the plug of your gadget. At any rate, PowerZoa transmits details on your power usage to a secure website, where you can use the interface to turn specific devices on or off.

Sooner or later something like this will be widely available, and there will be a cellphone app that would allow me to control everything. And when that happens, I will be all over it. [Powerzoa via DVICE]
