Super Flat and Retractable Cord
River Cheng a.k.a. Ho-Tzu designed this super-flat retractable extension cord to prevent tangles. The slim structure of the cord is possible thanks to the use of polysiloxane (a silicone polymer). All you need to do is give it a gentle tug, and it’s back to the house. Retractable Tape Cord is a 2010 Red Dot Concept Design Award Winning Project.
Designer: Ho-Tzu Cheng

I'd like to purchase one but I cannot find a link to tell me where they are sold. Also the description does not say how long the extension is in length. Do they come in various lengths? What about different colors to blend in with various surfaces.?
If this made the red dot awards, you'd figure the length would at least be mentioned.

Seems like some of these designers could do with a dose of physics…
The amount of current a wire can carry is largely determined by the cross section of the wire. The safety of a power cord is largely determined by the thickness of its insulation. A ribbon has an extremely poor ratio of surface area to be covered by insulation versus cross section to carry current. So for the same safety and current carrying capacity, a ribbon cable like this will actually be much more bulky than a simple round wire.
Put it another way: there's no way they can make a ribbon that thin, carrying 110 or 220V, without it being an obvious health and fire hazard. Just imagine if that ribbon got folded up on itself, and someone rolled over it with a desk chair?
Great design. Stupid idea.

im sorry to say that but what i see is an Apple power adapter with additional parts which absolutely wont fit together in color and form. But a nice idea..
