One may listen or transmit speech or song to the uttermost parts of the world." Tesla also predicted the wireless transmission of power; give us time, Mr. Tesla! Also see this video of a presentation by Popular Mechanics' Seth Porges; this topic is referenced near the end of the video.
"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
