Now is 2012. Is " this curious apparatus" the "fundamental part of
modern
radio"? Of course in form of the " variations of Tesla coils and Tesla
coil circuits".

No and yes. Tesla coils are not used to provide high voltages and sparks,
but resonant circuits, which a Tesla coil is, are used.

So in your transmitters are the coils made of wires?
Where can I find the scheme of a simple todays transmitter with the coils?
