RFID-controlled power strip only turns on when you're nearby

Whether it's from convenience, habit, or forgetfulness, we tend to leave our devices plugged in and on (or on standby) throughout the course of the day, which can account for a significant amount of wasted power over the long run. But there's a new device that aims to automate the process using smart proximity sensing, which could possibly cut your electricity use by up to 35%. The Pinch, from Birkeland Current, is an active RFID-controlled device that promises to make it easy to conserve energy at home or the office, without any other effort, and is currently in a crowdfunding campaign on Kickstarter.
