The problem of wireless power transmission differs from that of wireless telecommunications, such as radio. In the latter, the proportion of energy received becomes critical only if it is too low for the signal to be distinguished from the background noise. With wireless power, efficiency is the more significant parameter. A large part of the energy sent out by the generating plant must arrive at the receiver or receivers to make the system economical.
This technology can be used not just for charging but for using it for other purposes too. Read "Bye Bye Batteries" article from NewYork Times to know more.
Concept :
Concept of this project is very simple. We all know that Radio waves have energy stored in them, what we are trying is to convert its energy into electric current and store it into the batteries bundled with our mobile phone.
