The Power Aware Cord was designed by Static Energy+Design Network with the intention of making people aware of the amount of energy they consume. The concept is that if people can see how much energy they’re using, they are less likely to leave their PC running all night. So, this great light show of a power cord is not meant to dazzle, but rather, to remind you of how much energy you waste. The power cable glows and pulses when electricity is flowing through it. The more energy flowing through the brighter the cord glows and the more it pulses. But I can imagine people purposely leaving their PCs on just so they can see the cool cord glow.
