Wireless Cellphone Charger?

Amazing! Within a year or two, we will be able to forget about plugging our cellphones to get it charged. According to an article by Jonathan Fildes on BBC.com, "Eric Giler, chief executive of US firm Witricity, showed mobile phones and televisions charging wirelessly at the TED Global conference in Oxford." We can finally get rid of those tangling power cables in the back of our TV stands and our desks! It's a technology used in many home appliances already but just extended to further distances.
Watch the Video




Here is how the wireless power works,
1. First magnetic coil (Antenna A) housed in a box and can be set in wall or ceiling
2. Antenna A, powered by mains, resonates at a specific frequency
3. Electromagnetic waves transmitted through the air
4. Second magnetic coil (Antenna B) fitted in laptop/TV etc resonates at same frequency as first coil and absorbs energy
5. Energy charges the device

I can't wait till I get my hands on it!!!
