This has been implemented: in every RFID reader. The difference between this thing and a radio is that this thing supplies its own power; RFID tags get their power from the radio transmission. You may have noticed, however, that RFID tags generally only work at very short ranges.
There are a few major reasons that this doesn't scale, but the big one is the inverse square law. The efficiency of the system is inversely proportional to the square of the distance between the user and the tower, whereas the efficiency of wires is inversely proportional to only the length of the wire.
I am not, by far, an electrical engineer/scientist, but the inverse square law applies to vacuum. All the details about Tesla using the Earth and the ionosphere as a conductor may have meant that he was trying to solve the power loss problem. Do we have any details on that angle?
I know nothing about electrical engineering but there was a documentary on the history channel about this and they interviewed the leading researcher(a professor in the US) and he basically said no ones ever built a tower the size of Teslas to actually test if his theory would work, it didn't get into the details of why the experiment couldn't just be scaled down. But I think he implied there was some sort of critical size you need to get to where it would become efficient.
