Want to know just how much of a power guzzler your home is, and when are the peak hours where you use up the most juice? Deductive reasoning might be fairly accurate, but to get the best picture, this Visual Voltage clock concept by Swedish designers Loove Brooms, Karin Ehrnberger and Sara Llstedt Hjlem takes the cake where it offers a real-time representation of your electricity use throughout the past 24-hours. It will connect to your power meter through some magical, unexplained means, where the blue color lines represent your electricity use at the appointed hours.
