LG introduces its Wireless Charging Pad

LG introduces its Wireless Charging Pad
Today, LG debuted its new wireless inductive charging pad, creatively named the Wireless Charging Pad (WCP-700). Like other inductive charging solutions, the WCP-700 uses inductive coils in the battery doors in order to absorb charge from the mat itself.

The WCP-700 is special in that it includes a number of usability features, like audible and tactile alerts. When your device is correctly placed on the WCP-700, you will hear a distinctive tone, and feel a quick vibration. And this might be necessary, as the WCP-700 is only effective when your device is within 7mm of the mat's center.

There are also LED status indicators that will give you a progress report on the charge, without you having to get up and check the phone itself. A blue light indicates that the WCP-700 is plugged in, an orange light indicates that it's ready to charge, a flashing green light tells you your phone is still charging, and a solid green light indicates that charging is complete.

The WCP-700's size seems to indicate that you can only charge one device at a time. But that shortcoming is overshadowed by its portability. At 4.4 ounces, with dimensions of 6.29"x3.54"x0.39", the WCP-700 won't be a cumbersome addition to your bag. There's no word on pricing, or the availability of inductive battery doors, but we expect all of their current/recent smartphone lineup to get the inductive doors shortly.

How about we focus on creating wireless electricity for all devices. We wouldn’t have to worry about charging batteries anymore. A battery would only be needed as a backup energy source.
They already have wireless extention cords. (thinkgeek sells it) The downside right now is it requires direct line of sight.

Then you need the antenna made of few thousands Kilo meter for transmitting signal. Electric signal is of frequency 50 or 60 Hz, where as the other radio wave frequencies are of 800000 to 50000000Hz. Those frequency can be wireless with less height of antenna,
calculation is f (frequency) = c divided by h. C is the velocity it is around 3x10 power 8 i.e., 3000000000 and h is height. U can check how much antennae height needed for 50hz.
