Now we have a new way to transmit (or broadcast ?) energy. According to this news in a near future we will be able to recharge batteries without any cable to connect it to an outlet. This would simplify all devices and avoid carry different power cords to different devices. But there is still a question: would the wireless power providers be so good as mobile phone are? If the answer is yes I will stay attached to power cords forever.
