Cable free to recharge your ipod & gadgets arrive soon!

Can you image a world where if you want to recharge your handphone,Ipod or any other gadgets all you have to do is just put it next to your tv or maybe just put it on a table. Welcome to a world of wireless. You don't require cable anymore to charge your gadgets...


IS this true or just my imagination? Come on, we are in a developed world and everthing is seems not impossible to happen anymore.

Maybe in the next 10-20 years, you don't have to bring extra battery for your laptop, you even don't have to have a battery to run you laptop. and even you freezer, icebox and your airconditioner can operates without cables on it!.

"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."

But this advanced technology also worrying us like boosting no of people with cancer and even can led to other electromagnetic related diseases. But Scientist said, the electromagnetic waves will only absorbed by gadgets not by human body. The best example to say this is that the electromagnetic produces is a key and the gadget is a lock, so the key can enter the lock but can't open it unless it is a right lock. (think a while about it :P)

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, told the Observer: "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."

The Silicon Valley company can currently use a laser to generate about 1.5 watts of power to a solar cell 10 metres away. This would be enough to power an electronic speaker or small LED (light-emitting diode) lights, but not enough to operate a laptop, which requires an estimated 30 to 50 watts. However, Graham said that the technology could comfortably be scaled up.

PowerBeam insists its laser does not pose a risk to users' health because it is simply moving heat from one place to another. Graham said that, if someone walked through the beam, it would shut down within a thousandth of a second, then restart once the path was clear.

The technology also promises energy efficiency because it would only power products when needed.

Concerns have been raised about a possible link between electromagnetic waves and cancer, but scientists insist that the energy would only be picked up by gadgets designed to "resonate" with the field
