An article in Science News last month describes the work of physicist Marin Sokjacic who demonstrated just that.The way he did it was to create two antennas that were inefficient in the transmission of radio waves, according to the article. The two antennas were separated by a few meters and one antenna was tuned to create a pulsating magnetic field with a “specific frequency and geometry” which the other antenna turned into an electric current.In a demonstration before an audience that included an incredible 18 Nobel prize winners, at Berkeley, the MIT-based scientist lit a light bulb without wires.The hope is that over time, the antennas will be small enough to fit inside a laptop computer, a cell phone or an iPod so that users could recharge their devices while sitting in a special area in an airport, not unlike the hot spots we have today for Wi-Fi. Pretty cool, huh? Technology Industry
