Intel Corporation's chief technology officer took a fascinating look at how technology will bring man and machine much closer together by 2050.


Justin Rattner, during his keynote today at the Intel Developer Forum in San Francisco, predicted big changes are ahead in social interactions, robotics and improvements in computer's ability to sense the real world. He said Intel's research labs are already looking at human-machine interfaces and examining future implications to computing with some promising changes coming much sooner than expected.

Cutting the Last Cord, Wireless Power

Imagine being able to walk into an airport or room with your laptop and instead of consuming battery, it is recharged. Based on principles proposed by MIT physicists, Intel researchers have been working on a Wireless Resonant Energy Link. Rattner demonstrated powering a 60-watt light bulb without the use of a plug or wire of any kind, which is more than is needed for a typical laptop.


The magic of WREL is that it promises to deliver wireless power safely and efficiently. The technology relies on strongly coupled resonators, a principle similar to the way a trained singer can shatter a glass using her voice. At the receiving resonator's natural frequency, energy is absorbed efficiently, just as a glass absorbs acoustic energy at its natural frequency. 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.
