‘Wireless power’ spells end for cables

LONDON: No more batteries, no more chargers and no more wire spaghetti. This is the future promised by ‘wireless power’, a means of broadcasting electricity through the air to laptops, iPods and other gadgets without the need for cables and sockets.

Untethered lighting, audio speakers and digital picture frames are expected to be among the first commercial products demonstrated in Las Vegas this week at the International Consumer Electronics Show, the world’s biggest gadgets tradeshow.

Experts believe this is just the beginning and that eventually wireless electricity dubbed ‘WiTricity’ by some could do for battery life what WiFi did for the internet.

In a world without wires, laptop users in cafes and airport terminals would be inside an ‘electricity hotspot’ and no longer have to delve past legs, bags and furniture in search of an awkwardly located socket.

“You’d be able to buy a desk that charged any gadget placed on it, or power any PC you put on top,” said James Holland, editor of gadgets website Electricpig.co.uk.

“If each room had wireless power, you’d know that once you walked through the front door your mobile would start charging up even while still in your bag or pocket. You’d never need to hunt for the right charger again.”

Among the companies showcasing the ambitious technology at CES is PowerBeam. Its system turns electricity into an invisible laser, then literally beams it, as heat, across the room to a solar cell that converts it back into electricity.

David Graham, the co-founder of PowerBeam, said: “We’re going to delete the word ‘recharge’ from the English dictionary. If your cellphone is recharging on your desk all day, you won’t be thinking about it.”—Dawn/ The Guardian News Service
