I really like the idea behind this new power aware cord from Interactive institue. When the cable isn’t delivering any power it looks like just any other power cable, but when it’s in use it glows and pulses. The more power you use, the more it glows. Inventions like this is very important to be able to halt the global warming and spread awareness about the problem.
