Designer Meysam Movahedi has created a concept of the extension cord that you're looking for, It's the 1.5 meters long cord that unravels from a hidden cavity behind it's socket. When you need the extension, simply pinch the sides and wind it out.
Once you are finished with using the extension, the socket has a built in recoiling system, gently give the cord a little tug to activate the spring mechanism, and it will recoil back into place. It's perfect for using with electronics like, vacuum cleaners, hair driers etc any item where you don't need an extension cord on a permanent basis.
