Are you bored with keeping tabs of your carbon emissions? NEC and BIGLOBE have developed a system that not only performs this odious task, but makes it "fun" to do so -- if you're generous as to what constitutes "fun." A WiFi-enabled device is attached to your circuit breaker, where it keeps track of your power consumption and later transmits it to your home computer via ZigBee. The data is then sent to a website, where you can use it to play games against other green households in such thrilling arenas as Carbon Diet (users score "eco-points" with which they can purchase virtual soil, water, flowers and grass) and Carbon Ball, in which Dung Beetles compete to see who can travel the farthest, with distance being determined by -- you guessed it -- how well the user reduces power consumption. But that ain't all -- the system also keeps tabs on daily and hourly energy consumption, your rank in comparison with other households, and more. A three-month trial service is underway in the homes of 100 NEC employees, after which the companies will analyze the data and develop a business model for unloading this bad boy on local governments and the private sector. One more pic after the break.
