Ok first off I am sorry because this probably isn't in the right section but didn't know where to put it. I have to come up with a report in one of my classes about power distribution. I am just curious if this would work theory wise. I am not going to make a working model or anything this is more just an assignment to learn how to brainstorm. Ok so here it goes. Would it be possible to transmit small amounts of power through radio waves? My this I mean is it possible to have a speaker hooked up to an electrical source which cause the first speaker to vibrate back and forth rapidly (like a normal speaker does). You would then put another speaker in front of it. The pressure of the radio waves would then make the other speaker fluctuate back and forth and move a core back and forth through some windings to create a voltage. I would mount both speaker inside a closed, sealed bow to contain the sound waves. Would this be at all possible do you think?
