Produce Electricity from unused Radio waves?

[Drakkith]

Hey what if a produce a electromagnetic radio wave from my 240v wall socket converting that to 10v which produces a radio wave at say 2.4ghz then harvest it from 30meters away to a small copper antenna which the produces the radiation back into electricity to glow a led.

Do you know how?

Buy a 2.4 GHz radio transmitter and plug it into your wall socket.
