    And, i think 'hf' alternators (which work others followed up on).
    As to 'missing' the early work, i reccommend
    reading:
      Experiments with alternate currents of High Potential
      and Frequency
      by N Tesla.
      (Title from memory, tho i think thats right.  Available
       in reprint, tho, decades back, i lucked onto a vintage HB
       copy)

     The subject was coils, rather than applications.

     cf as above.
     It is, perhaps, useful to recall that until the days of
     the vacuum tube ALL WIRELESS was 'transmitted energy':
       What was heard, or whatever was the teeeeeny fraction of
       that energy that made it to some one point.

     I was not gonna mention it, but since we have wandered to
     early wireless, BBC currently has a program up on their
     web site on another forgotten pioneer:
       Reginald Fessenden, aruably the first to sucessfully
       do voice transmission (It has some technical and
       histrical clunks in it  8)>>  (I collect old books
       8)>>))

     One access is
        www.bbc.co.uk
           find 'radio'
              thence to 'programmes'
                  thence to 'A-z', select Discovery
                     Click oon oneof the audio feeds...


     And let me add my thanks for the Edison Quote.  Was there a
     Date i missed?

     And, lastly:
       Best of the Season to All
