I am sitting through Day 3 keynotes and now it's the Research and Development keynote session with Justin Rattner. Lots of pictures to load later, but I wanted to post this one because I think it's the big thing out here: wireless power transmission.Unlike those "wireless power" gimmicks shown at CES, which require special connectors and devices actually touch the power source, this one transmits power over the air - we are talking about 60 watts power over two feet, at 75% power efficiency.Based on principles proposed by MIT physicists, Intel researchers have been working on a Wireless Resonant Energy Link (WREL).WREL promises to deliver wireless power safely and efficiently. The technology relies on strongly coupled resonators. Intel says that with this technology enabled in a laptop, for example, batteries could be recharged when the laptop gets within several feet of the transmit resonator. Many engineering challenges remain, but the company's researchers hope to find a way to cut the last cord in mobile devices and someday enable wireless power in Intel-based platforms.Here are some pictures:Other related posts:
