I shudder to think how much money offices and homes around the country could save if they used the HiSaver Powerbar. The HiSaver Powerbar uses a motion sensor to turn off all but one of its outlets every time you leave the room for ten minutes or more.
You would presumably plug your desktop into the outlet that never cut off, with all other unimportant items getting the axe after 10 minutes. The HiSaver Powerbar is definitely an essential for businesses or homeowners trying to cut costs.
