Plugs and wires could soon become a thing of the past

The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past.

US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players wirelessly.

The concept exploits century-old physics and could work over distances of many metres, the researchers said.

Although the team had not built and tested a system, computer models and mathematics suggest it would work.
