Wireless Charging !

Are you tired of your mobile's batteries dying out when you are in the middle of an important phone call, or the batteries of your mp3 player going dead when you are listening to your favorite song, or your camera giving up on you just when you are about to take that all important picture just because you forgot to charge the batteries last night? Well if you are than this might be the thing for you. Scientists are perfecting a new method of powering devices without the need of wires or wirelessly.

The idea of beaming power through the air has been around for almost two centuries. It is used in some extent today to power some Radio frequency Identification (RFID) tags. The phenomenon which makes this possible is known as electromagnetic induction or also as inductive coupling and occurs when electric current passes through wires like in a RFID tag.

When current flows through a wire it creates a magnetic field just like around a magnet, this field in turn can induce current in nearby wires. This has a limited range however and is not suitable to power a roomful of devices, but scientists have developed methods by which this induced current can be boosted and can successfully power devices like a battery charger.

Automotive supplier Visteon has already announced a wireless charging device that can charge batteries on mobile phones, mp3 players or handheld computers without the need of an adapter. They claim that this wireless charger can charge a device with the same speed as a conventional charger.

The new visteon wireless charging concept that allows users to charge an ipod,cellular phone or a PDA or any other compatible devices.

This sound to be a great idea, and could change our lifestyle. But, will people use it? That remains to be seen given concerns over cell phone radiations and other power line radiations. The developers might have a problem convincing the people that it’s safe.
