Saverclip by Yanko Design

While very much a concept right now, this is a very well thought-out product. Called the SaverClip, it does one thing we all want to do but find difficult or impossible: see how much electricity we're using. You simply clip the SaverClip across the power cords of your devices. By sensing the electromagnetic fields emanating from the wires, it can tell how much electricity is being used. It also draws power this way, siphoning some off from the cables so it never needs any batteries. Very cool idea, very cool design. I would love to see this made.
