Everyone wants to go green these days, and the Wind Up Socket concept device could very well help you in that particular quest. How does it do so? Well, the Wind Up Socket basically prevents you from spending more energy than you should, as long as that is limited to devices which are plugged into a power outlet. All you need to do is set the duration on the Wind Up Socket with some winding and leave it be. Once the time is up, it will automatically cut off all juice from the grid. Doesn’t sound like something we don’t already have in the market for years – your regular power outlet timer.
