The Rambler is a very solid electrical outlet concept that completely eliminates the need for extension cords. The Rambler is just like a normal socket but pinch the outside to release it and hidden behind the plug is a 5 foot long spool of wire. The spring loaded spool retracts back with a simple pull. Designed by Meysam Movahedi, the idea is great, as long as you have the space within your wall to hold all that wire. It would be ideal for vacuum cleaners, hair dryers, and anything else that only requires an extension cord for a brief period of time. I like this design concept- could be a winner.
