It’s about time the big companies are killing the power cord. After Dell unveiled a notebook that can be charged wirelessly, it now seems to be Sony’s turn to do away with those cables. The company has announced this past weekend [JP] a power transfer system that can bring electricity to electronics wirelessly.

The system is still in experiment stage, but Sony says it’s already capable of sending 60W of electricity to a 22-inch LCD TV that’s about half a meter away. The distance can, at this point, be extended to 80cm when using a repeater. Another potential device the system could be eventually used for is a laptop.

Sony uses magnetic-resonance-based technology to transfer electricity from the transmitter to the receiver. The company is now working on commercializing the system but hasn’t said when we’ll see it in action.
