Mobile Auto Charge

I had thought of this concept when I saw a blinking panel attached to most of the mobile ( for showoff) a few years back.

I was amazed about how the light blinked without power. Then when I learnt telecom I know it was Power transmitted from BTS.

When we can light up an LED then why not charge the mobile?

A power wave is continusoly broadcated to our mobile frequently frm the BTS to locate our Mobile/Keep track of it. The Power radiation can be then amplified and used to fuel the mobile.

We can make the backcover of the mobile as a reciever of such signal and charge the mobile.
