Wireless charging of cars may still be the stuff of science fiction, but wireless charging in a car won't be for long. Bloomberg is reporting that General Motors will integrate Powermat Technologies' wireless charging tech into some of its vehicles next year, allowing wireless recharging of compatible phones. GM , which is one of Powermat's investors , is attempting to beat both Toyota and Chrysler to bring wireless recharging into the car. The technology, which uses a coil to interact with the magnetic fields generated by a Powermat to transfer electricity, has been available to consumers for some time, and is only expected to become more ubiquitous in the coming years. According to Bloomberg, wireless charging tech will expand from the five million units sold in 2012 to nearly 100 million by 2015.Bloomberg spoke to Dan Flores, a GM spokesman, who refused to comment on when and in what vehicles wireless charging would appear in, "We continue to work with Powermat to bring their technologies to GM products, but for competitive reasons we're not discussing specifics at this time. The technology continues to move forward."What do you think - does wireless charging tech have a place in the car? Would you rather have a single cord to charge and play music from your phone, or would you like to see wireless charging join Bluetooth streaming in keeping the car and the phone physically unconnected?
