how can we design a circuit which could detect radio frequency available from mobile towers and convert it into electrical energy to charge mobile?

same idea igot few years back. im telecom engg stu. its in my field.
have you got some success in research for this idea.

[Ashutosh Bhatt]

do you know what is the signal power received by your mobile?

with full strength you will get signal strength or around -50 to -70 dbm

that means it will be in terms of few 100 micro Watt

if you want to charge mobile from it then you require huge amplifier. it can not be portable
