Has it been done? If so, how do I do it?

Easily. Just connect a bridge rectifier between any antenna and ground and use it to charge a capacitor. Electromagnetic waves at all radio frequencies induce current in the antenna. It's just not enough to be useful.

Frank N (previous responder) has the right idea, but a rectifier won't have a sharp enough rectification curve to produce noticeable power at the voltage levels prevailing in radio static -- we're talking microvolts.

radio static isnt being generated or broadcasted... radio static is the sound of emptiness. its the sound that you hear when radio data is missing or is jumbled.
so you wouldnt really be able to harness it because theres not really any energy to harness.
