Our solution was to build a device that would be able to hold more USB's and would connect to the computer by bluetooth. One the device was Idle for a certain amount of time the computer will send signals to turn off 

Problem Statement
Those who rely on computers, specifically desktops, waste a lot of electricity when idle. According to studies, “This always-on energy use by inactive devices translates to $19 billion a year -- about $165 per U.S. household on average -- and approximately 50 large (500-megawatt) power plants' worth of electricity.” Currently, there are minimal devices that cut down this power cost automatically.
