Velcroman1 writes: The army's secretive technology division has been collecting dozens of ideas for the design of its in-the-works rescue vehicle via a social-media contest — relying solely on the power of the crowd to get the next big thing built. Local Motors of Chandler, Ariz., is running the competition, officially known as the Experimental Crowd-derived Combat-support Vehicle (XC2V) Design Challenge, through March 10. It’s not so different from when multiple users edit a page on Wikipedia, Local Motors CEO John Rogers said. “Effectively, we want to co-create all aspects of a vehicle,” Rogers explained. “The Wikipedia method of co-creation is really not far off from the way we talk about it."
