Hi, well, it seems we are of the same inkling of understanding. 
You are quite correct in the 'lost inventions', and your other
observations of the writings you speak about. Sounds like you just posted
a "free power" system, and elaborated on the subject of the difficulty in
tuning the two coils (sending and receiving) as a compatible unit.  I
have no doubt this will work, since I have already utilized a send and
pickup set of Tesla coils and I do know that it will work.  And with a
large enough power supply (such as the Wardenclyffe tower), there is no
question that it will work. Tesla said it would!    Al.
