The purpose of the orb is to provide a visual representation of the current load on the grid, manage demand and hopefully avoid brownouts. A red orb means that demand is high and turning off extraneous electronics immediately will help lower demand. A green orb indicates low demand. All you have to do to run the orb is to plug it into a wall outlet. Information is relayed via the 900 MHz broadcast spectrum and as soon as you plug it in, info is automatically received to inform you of the current energy demands. No internet connection or computer required.
